Rebuilding FEL should I switch from NPT to JIC

woolyAcres · Oct 9, 2015

Although I haven't done the rebuild yet I'm planning to do it with NPT. It's going to be simpler, less expensive, and if it last for 30 years the way it did the first time, I'll be more than satisfied.... There are just too many NPT parts that aren't being changed- cylinders, fixed lines, etc. Moving to JIC would mostly be an academic exercise- convert from NPT to JIC then back to NPT to connect to the hardware I already have. If I were scrapping everything I'd certainly go JIC but for this project I don't think it makes sense.

I do appreciate all the input.

I would splurge for the Loctite 545 hydraulic pipe sealant and forgo the use of any teflon tape products. Its good for up to 10,000psi and hardens to form a good seal on even deformed threads.

I would completely avoid tape and use some kind of liquid. The little shreds can get stuck in valves and quick connects.

I've heard this more than once and it seems like a good way to go. Thanks.
