I prefer to use thread dope instead of teflon tape. It acts as both a lubricant and a sealer.

Also, when using the quick release fittings like the Prestolocks, I use a bushing in the end of the plastic line to keep it from bending or crushing at the fitting end... either of which will give you a bad seal. As I said earlier, my truck sat up for several months during a north Texas fall (cool mornings, hot afternoons-- lots of air density changes inside the system) a couple of years ago and it didn't lose ANY air whatsoever.

And... about the RideTech valves, they have the ability to "self clean" to some extent in that when the valve is opened, air pushes out through the orifice and can help keep it clean. A typical spool valve, when it kicks the axle one way or the other, can create buildup at those side-to-side stopping points if your air supply isn't nice and clean. And they are less able to self-clean because the air supply doesn't blow across these points, but rather it blows through the vanes on the axle itself.

Just a few tidbits I've picked up...Teflon tape is a big no no in the world of air suspension, pieces can come lose and make valves stick open...I know Roadsurfer (Bill Dermond from Airlift) recommends using RTV on the pipe threads...A little goes a long way....

70 Jimmy · 09-19-2002, 06:12 PM

That's interesting Shev. It will be OK if you make sure you clean old tape off and only tape the threads. The tape has a tendency to stretch over the orifice like saran rap and that's a big no, no. The RTV trick is probably for outdoor use. I work in a relatively clean environment so no worries there. Thread dope is good stuff and many fitting manufactures will have that already on the fittings.

Also, check the manufacturers recommendations on lubrication on the valves. Many valves nowdays don't require any oil and in fact some will experience premature failure if oiled. Use only recommended oil. Most companies don't bother will their own brand of lubricant so no price mark-up there. Most of the machines I work on run million cycle non-lubed valves for psi ratings up to 300#.

sup guys,
that thread dope is the one that comes in a liquid form from a little bottle right?

If so, I did that on my s10 with no leaks.

70 Jimmy: I've tried the soapy water trick before, but I must have missed some connections. I'll have to do it again after I clean off all the teflon tape and apply the pipe dope

Thanks for the suggestions and advice!

I'll try to get you a part number for the valves. I bought them from AIM.

Yeah, it's usually a can with a brush built into the lid. It's gooey looking and tastes great on Ritz crackers. Wait... don't eat the stuff. I was kidding about that part!

oh...mine came from squeeze tube (like toothpaste). I'll have to see if the local hardware store has it.

Could very well be the same stuff. I bought mine from a "commercial" supply house so I may have gotten the jumbo contractor size.

I just dug through every receipt I could find and didn't see it. It's been a year or so... it was something like "Billet Wholesale" ??? I found them in Truckin'. I'll keep digging and let you know if I find the name of the place.
