Thread sealer...what kind for your N20 system???

**Snake Bitten** · June 17th, 2003, 11:29 AM

What kind do you all use??? On the NPT fittings, not the Aeroquips...

Is this a 2-day or 2-month install??

Do you really want to chance some sealant getting in your solenoids or jets?

You have to use something, or the NPT's will leak...

NX has a liquid sealant.

Then I don't know what to tell you.

Teflon tape can get into things and you don't want to have the fuel flow stopped or interrupted and go lean. The nitrous flow either for that matter..

Time for you to e-mail BTR/Tom Welch

He would know, or Albert C.

The reason I ask, is I am thinking of going to a Loctite Thread Sealant, probably the 574...

Regular thread sealants just ain't cutting it...

Well if they are not working you just might have another problem with the fittings themselves.

Did you over tighten the fittings at all in an attempt to make them seal?

Nah...I am just not a plumber...and was using crappy pipe dope...Loctite should do the trick...

Gerald, I was waiting to see all the response, before I jumped in.
I just used the loctite teflon sealer in a tube for the pipe fittings.
On the compression fittings, any inert lub would be ok, or just use nothing.
I think the caution about combustible lubricant on the NOS lines is a little
overstated, as long as its conservative.

**Jerome** · June 17th, 2003, 03:53 PM

Use the Loctite to seal the fittings not the thread locker.

That is all that the NX liquid is anyway.......... Loctite sealant

I guess understanding the sealing nature of NTP threads and the mechanism
of compression fittings, give you some insight into what works best.
Even though NTP thread are interference cut to provide an almost total seal,
for good measure an extra sealant is applied.
Compression fittings benefit most from a lubricant that will allow you to
apply just the right torque to create the metal to metal 45deg or 70deg seal.

From what I remember using tape is a no no and what is recommended is a teflon sealing compound.

you may want to contact the maker of the connectors and see what they recommend.

Simple- pick up the WHITE tube of loctite teflon PIPE thread sealer.

Exactly, most people have no idea that NPT threads are not the same diameter along the length of the threads. They are tapered.

When I worked in a machine shop I would spend days making NPT threads in expensive items we produced. I screwed up more then one buy going to deep with the threads.

They "should" seal on their own just as Hugh said, but they do not always work that way.

As they say, "Shit happens"
