How much Nylog to use on o-rings

emobley on Sun September 19, 2004 12:42 PM User is offline

Hi,

Just want to make sure I'm using the right amount of Nylog on my o-rings. I put Nylog on the tip of my index finger and rub it on the o-ring between my thumb and index finger.

However, I've heard that one should "string" Nylog on. I guess I would have to see the technique, but it sounds like it would be easy to use too much.

Thanks,

Ed

Either way is fine..On threads I dab a bit on and string it around the threads..If using your finger, be sure it is "clean" of drit and grime..Hope this helps..

Why anyone would use nylog is beyond me. I've been doing a/c for twenty years and never used it, I've never had a leak after thousands of cars so I fail to see the necessity. I just dip the o-ring in the oil and put it on the fitting and tighten it up. Once the o-ring is compressed inside the fitting, there's absolutely no way it could ever leak unless you misthreaded it or something. I laugh at people who use nylog. You know how tight the fitting has to be to compress the o-ring, to withstand the pressures of an a/c system? Once the o-ring is compressed, that's it, NOTHING is getting past it, nylog or no nylog.

Nylog is NOT meant to be a sealer...It conditions the O ring and keeps it from drying out. Also helps when you have to take a system apart where the nuts on the accumulators and other parts are so tight from the bonding of dissimular metals that they have to be sawed off...Nylog prevents that from happening. But, opinions are like a**holes, everyone has one, and you are entitled to yours...So, laugh away..

I've noticed that in some fittings the o-rings really get squeezed and in some they come our looking like new. In the latter case, should or thicker O-ring be used? Or more than one o-ring be used?

Thanks,

Ed

Maybe you should try a bottle you might just learn something new! Never had a leak in a system in 20 years that is amazing. Dipping an o-ring in oil is fine. But if there is a better method why not use it! Nylog is an excellent product, which I would recomend on all a/c connections!

Nylog works great just as Chick said. It is possible to break connections open much easier when using Nylog on the threads. It's also a Godsend for Ford springlock connections!!!

I do my own work, but I'm no expert. I used the stuff because people who are experts advised me to. If nothing else, it's a belt & suspenders thing....
