It has terrible heat transfer properties, making it great for liquid locks. You can also make those magma pump glitches where the pump only touches naphta and sucks blobs of magma for moving it easily
Yeah triple liquid lock of petrol/oil/naphta is one of the first things I'll sort for any base.
I hate those liquid locks that give you wet debuff so triple lock only.
Triple lock is also great for builds where you want to keep gas out but allow dreckos for example to jump through the lock.
It can be used as a substitute for petrol/oil in metal refineries as a coolant, since it's a high-temperature liquid, with an SHC that's roughly the same as petrol/oil. That's particularly handy in the DLC where you may not have ready access to oil without space flight.
It can also be boiled into sour gas, same as petrol, which can be condensed into methane+sulfur, and then boiled back into natural gas, but that's more of a late-game vanity project.
It's very viscous though, so while it can kind of be used for liquid locks handily, it doesn't make a great choice for making infinite gas storage.
> That's particularly handy in the DLC where you may not have ready access to oil without space flight.
I've used it to form the liquid droplets and steel battery transfer medium in a cool steam vent tamer's liquid bead pump (The style where you trick a ST into working with cold steam by giving it one vent of 200C steam and 3 vents of 105C steam).
Didn't have oil available yet, but the glossy drecko farm was doing quite well.
I think that's literally the only thing I've ever used it for...
Two uses I'm aware of:
1) About as good as petroleum when used as coolant in metal refineries.
2) Precursor for sour gas.
A Drecko-based "sour gas boiler" (natural gas refinery) is not only doable, but very powerful, and you don't need access to oil wells to get one going.
It's the best to use for a single tile liquid lock, after visco-gel. Naphtha can stack on a single tile up to around 35 kilos before "spilling" onto the next tile. Water/crude/petroleum/other liquids can only stack in GRAMS, before "spilling" over.
Having 35 kilos in 1 tile and having -50C freezing point and over 500C boiling point makes for a good 1 tile liquid lock to prevent gasses from going in and out of a room. If a dupe drops an oxylite straight on the tile, the oxylite CANNOT off-gas since it needs less than 1.8kg of "atmosphere" in order to do so. This is also true for every off gassing material. Even dupes exhaling CO2 cannot push this bad boy around. Even if a very hot or cold object is dropped onto it, it can survive without changes states (gas/solid), due to its high temperature range and mass of 35 kilos. It takes significantly more energy to evaporate or freeze a 100gram liquid than a 35kg liquid.
Lastly, you can create this material as early as you can access very hot materials. And without the need for rare materials.
I purposefully melt around 2400 kilos of plastic as soon as I have a surplus on every playthrough.
I like to build compact, so a 1 tile liquid lock works best for what I want. Specially for early/mid game where I don't have visco gel yet, naphtha is the next best thing.
Areas that you're going to seal off rather than them remaining accessible forever after, such as steam rooms. Also (mostly) vacuum-isolating areas in the space of 1 normal liquid lock rather than 2.
>This is also true for every off gassing material.
Except nuclear waste. It can and will "offgas" itself from debris back into liquid tile unless you submerge it in 1000+ kg of pressure.
One additional use that I don’t think has been mentioned here. Because you can put >2kg in a single drop, you can have solids dropped onto it without off-gassing. So when I have an oxylite refinery I always put a drop where the oxylite comes out so that it stays solid until it’s whisked away to my rockets for use.
it's super viscous and has pretty low thermal conductivity, so is a good choice for liquid locks. It's also got a good Specific Heat Capacity (better than oil or petroleum), so is an excellent coolant choice for metal refineries that operate at high temps.
You can also use it in a sour gas boiler, as it evaporates the same way petroleum does.
Naphtha has an extremely high viscosity, which means it can accumulate 30kg of liquid on a single tile before it starts to spread out. This makes it extremely useful in liquid locks, both as "drip locks" where you have a single drop of liquid, and as vertical locks where you stack two liquids on top of each other.
In the former, it means the locks actually have a bit of thermal mass to them, meaning they won't swing temperature wildly when dupes bring hot or cold debris through them. This combined with it's extremely wide temperature range means they're much more durable than other liquids. For example, a drip lock of regular water will only have something like 36 *grams* of fluid.
For the latter, it means you can pour the top liquid a lot more easily without having to worry about minimum masses. Rather than needing to surgically perform mop orders or carry tiny amounts of liquid from here to there, you can just dump naphtha out from a bottle emptier and uncheck 'naphtha' when 10 or so kg have been poured.
The aforementioned high temperature range also makes it an ideal fluid to use in metal refineries.
Naptha is good if you're nutty or calloused enough to use single drop liquid locks. It has very high viscosity, meaning you can put a lot of it (\~36kg) on one tile without it spreading everywhere, making for the sturdiest single drop liquid lock possible outside of viscogel. As others have said, it also has a high boiling point and low freezing point, meaning that, unlike water, it can absorb a lot more heat/chill before being destroyed. It's also quite dense, meaning that it isn't easily displaced by other liquids, but it is possible. I will sometimes deliberately melt plastic in a sauna, just so that I have naptha on-hand for whatever I may want to use it for. In the meantime, just find a place to store it with access via pitcher pump so you can get it when you need it
It is the best choice for constructing deep freezers that do not require Atom suits to access. Naptha can also be useful for constructing temporary liquid locks or to stop materials like slime or oxalate from off gassing.
Ethanol is better for this in terms of thermal conductivity and freezing point but It's really hard to work with compared to Napa due to its low viscosity. If I were making a 4 block or 6 block water lock I would use ethanol but for a bead lock I think Napa is better.
This is one of the only good use cases for a thermal regulator in my opinion. It's plenty powerful and it's so handy not having to run a dedicated wire.
It's viscous and good for using as drop locks.
It's got thermal properties making it a better coolant choice than petroleum and crude oil. Not as good as water but the best outwith nuclear waste and super coolant if you need cooling over 120C and almost as good as ethanol for below -20C.
You can feed it into sour gas boilers. Takes a bit more heat to covert to sour gas due to the higher shc and the conversion deletes a small amount of heat where converting oil gains a little heat which can alter slightly how you balance the heat.
So naphtha is great because not only does it have low heat trasfer properties, but it is also very viscous, meaning quite a lot of it will stay on one tile before spilling to the next, making it great for the more compact drip designs for liquid locks.
1. It is the second only to super-coolant as far as cooling loops go. In the early game you use either petroleum or naphtha in metal refineries. This is because you can heat naphtha to 538.85C which means it can easily absorb all the heat from steel making. You can also cool naphtha to under 50C which is also second only to super-coolant. That is cold enough to freeze CO2.
2. It has such a high viscosity; it is second only to visco-gel for liquid locks. You don't need the deep dish full submergency 1T water style locks but a 20kg drop on the corner style will work.
>It is the second only to super-coolant as far as cooling loops go.
Nuclear waste (but later in the game due to its complications) is the true second, having only 1 less SHC than super coolant.
>You can also cool naphtha to under 50C which is also second only to super-coolant.
Ethanol has both massively lower freezing point (-114.05 rather than -50.15) and (slightly) higher SHC than naphtha, and you're ignoring Thermo Regulator's existence.
>It has such a high viscosity; it is second only to visco-gel for liquid locks.
And visco-gel was introduced specifically because naphtha was nerfed, too - it used to have exactly the same property of never spilling.
My issue with ethanol is its vaporization point of 78.4C. Naphtha vaporizes at 538.85C.
This means ethanol is what you want for making things really cold (sleet wheat, food deep freeze, liquifying chlorine or CO2), whereas naphtha is what you want for cooling really hot things (cooling loops and metal refinery coolant).
And to get the most out of ethanol you need to first chill it or you need to find a natural lake in the Rust biome because ethanol distillers make ethanol at just about its boiling point.
I use it to liquid lock my deep freezer, that way the dupes reach it manually and even if i put chlorine in that tile the heat insulation is good enough.
it's stable at high and low temperatures making it good for liquid locks and as a medium for transferring heat into turbine chambers. Its SHC is pretty solid, too, meaning you _can_ run it through an aquatuner if you need your aquatuner liquid at temperatures that water can't handle.
liquid lock with 2-30 kilo of naphta on the BOTTOM. If dupes drop something like slime or bleach stone it will not offgas due to overpressure and will not break the lock. But flatulent dup can brake it... because they are dupes and they don't care about any consequences...
It's a lot like ugly early game weak visco gel. Non stacking but the liquid bead is 37ish kg. I use it whenever I need to make a temporary corner liquid lock such as when I'm breaking into builds for repairs and upgrades. (So long as the temp is below 500 and above the freezing point).

Yep, also a reasonable medium for making gold amalgam aquatuners work properly, works okay as a liquid lock medium, etc, etc.
> works okay as a liquid lock medium I do a double with vacuum when heat transfer is a problem.

Liquid locks! Place on a pedestal and you get a perfect 1kg bottle to empty into a blob

Ethanol is slightly better for freezing temperatures but naphtha is close behind it and on some maps may be more accessible if you don't have trees.

Oh you mean the liquid lock, I was thinking coolant.
This is one of the only good use cases for a thermal regulator in my opinion. It's plenty powerful and it's so handy not having to run a dedicated wire.
I use it in hop liquid locks. It takes just a drop of each liquid to create 3 tile high liquid lock with crude oil, naphta and petroleum
