My Rix SA-6 Diesel

The paste is a lube that addresses the heat generated with wrenching the fittings together, allowing you to make the connection tight/leak free.

In my case, for ease of connection, all fittings were converted or transitioned to JIC for any hoses & tubing.

I have a few JIC in there, but there's a lot of stuff (so far) that should really stay together. Like the gauge - sight glass - PMV. Not really any reason that I can think of to have hoses in between.

If I ever get really fancy maybe I'll build a panel with compression fittings.

You really need to be able to very strongly mate those fittings.... At times, I used a vise to aid in the strength needed to make the connections. NPT and BSP are a beast....

I did use a vice for a lot of the fittings, but thankfully not the tower base.

I guess I should ask... what paste? I have plenty of "Gasoila", but I'm not sure if that is correct.

 

[rhwestfall]

correct, sub-assemblies are all NPT to NPT.

As to the paste, I was gifted a syringe of a modest amount to do the limited connections.

written on the syringe is "TFE Pipe Thread Sealant" and also included a note that it will stain clothing....

keep in mind, the tape or paste is to lubricate the fitting allowing you to mate the threads completely, and not really intended to be the sealing mechanism.

Understood.... it's the same in gas applications as well. It's just a lubricant.

If you're doing a lot of oxy compatible things on whips and what not, this stuff is good. Not cheap, but it will last you forever

I was just reading about LOX 8. Thanks.

@tbone1004, in your experience tape / paste? I don't need O2 compatible just yet, plans are to build a nitrox stick, but even that won't be above 40%-50% by the time it gets to the fittings.

Nitrox stick is low pressure after the regulator so doesn't have to be O2 clean.
Paste is a bit messier obviously, but I have lost a couple of SS fittings when the tape slipped and galled which the paste won't do

Just regular tape from say home depot?
