On fuel systems do you use anything to seal NTP fittings? I know that AN fittings don't use anything. Thanks.

 

Its NPT (national pipe thread)

I use some fuel safe thread sealant or teflon tape.

 

oops, my mistake. Thanks. Ok teflon is what I was making sure would work. Thanks.

 

fittings that use the THREADS to seal, use teflon tape or paste.. dont use tape on anything that might be damaged if a piece goes into the system (nitrous systems, fuel systems, ect)

if the fittings use a seating surface to seal, such as flare fittings, AN fittings, ect.. do NOT use any form of sealant on the threads.

if the fittings use a Oring seal, just make sure the ring is oiled before putting the fitting in.. do not seal the threads.

 

So then paste on all the fuel system stuff i guess. What is the best paste?

 

i like the PERMATEX stuff the best myself...

the pic there is of the tube.. i usually get the little bottle with the brush built into the cap.

 

Permatex thread sealant with teflon here, too. It's good stuff.

 

How about on N2O lines too, and solenoids? I got a kit used, but the guy that had it before did a good job sealig but an ugly job. I want to take it apart and do it again cleanly.
