37482 545 Pneumatic/Hydraulic Thread Sealant Bottle - 36 ml

Worked Great. Stopped a water leak at a pipe fitting that I’d been having problems with.

Original Review on May 12, 2013: I've used PTFE tape for years and have preferred it to pipe dope ... but this stuff has me sworn off PTFE, forever, in scenarios where the 24 hour cure time is not a factor. Apply it to the threads as a liquid and within 5 mins it begins to set up into a purple, pasty material -- plenty of time to get it threaded into place. Vibration resistance plus sealant in one -- I love it. Addendum Review added on April 29, 2014: Nearly a year later the onboard air system I built for my vehicle still maintains 200psi pressure with not a single leak; it has lots of fittings, and I used the bulk of the bottle on that project. Also, every pneumatic tool I own now has this thread sealant instead of PTFE tape where the industrial nipple is fitted to the tool -- no leaks. I purchased a fixer-upper home last December and needed to replace the hot water heater and pressure tank, and, again this sealant was used to produce fitted connections with zero leakage. I recently used the last of my first bottle when installing an interior (to home) 3/4" threaded ball valve and accompanying outdoor hose bib to bring water from my home to my dock, and I just received the replacement bottle I ordered. I will likely always keep some of this around from now on. A little bit goes a long, long way. I've also learned in using it that while 24 hour cure time is recommended, for non-wet, low pressure (i.e. less than 300 psi) scenarios, you can likely get away with a 15-20 minute wait. I've never waited less than 15-20 mins ... and those times when I waited only that long to use dry things I've sealed, I always had good seals. I'd allow full cure time for wet conditions, just to be safe, but that's me.

Good product quick ship as advertised

Just got done using the Loctite 545 with primer 7471 (Required with stainless steel) and also used 5452 (Gel Version, No primer required) and they are awesome. What "I" key word "I" as a novice could not do with teflon tape and pipe dope these products were able to. Not only do they seal really well, but they also create a tight bond like other loctite glues. Again, these two products are specifically designed for Pneumatic use. IMOP, they are very expensive and not practical for everyday useI on a job site. I just got tired of taking my airline pipes, cleaning with wire brush and acetone and reassembling/assembling multipule times. I would like

Used this to seal thread on skid steer female auxiliary fitting. Took several attempts to finally get threads to seal without leaking.

I was a pipefitter for 36 years and couldn’t count how many screw joints I have made. This pipe joint compound works great. I used it on a hydraulic log splitter on all of the joints, fired it up and did not have any leaks at all. Very impressive

Good for the hydraulic fitting I was working on.

I used the Locite 545 to repair an old air compressor. Working well so far.

ممتاز

Después de darle servicio a mi compresor, no encontraba la manera de que no tuviera fugas de aire. Intente con tanto Teflon como pude, incluso sus variantes industriales pero nada conseguía sellarlo. Probé con este producto, no teniendo muchas expectativas realmente y mi sorpresa fue que ahora no tengo ninguna fuga. Es importante mencionar que si se debe de dejar secar al menos lo que indica el producto (24 horas) aun que por el clima frío lo deje una semana. Lo recomiendo TOTALMENTE.

This was recomended by some repair personnel and it worked great for my connections that were leaking using another product. However, this has to sit for 24 hrs to be 100% effective.

Buen producto

As ordered not much more to say.
