Loctite37482 545 Pneumatic/Hydraulic Thread Sealant Bottle - 36 ml

Used this red thread locker for my big excavator hoses. It sealed the hoses so they don't come undone! No leaks, easy to use and works well! Just make sure you clean the threads well, no oils, use acetone to remove all traces of oil and grease!

Worked perfect.

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.

Needed this for head studs replacement on my Harley. Worked well good value for a mid sized bottle. Cap seals up nicely.

It can be a shock looking in the bottle and thinking about the price you paid, but it's well worth it. I've never had a fitting leak when properly cleaned and this stuff applied.

works fine to seal fittings of my 6 x 4 bandsaw hydraulic downfeed control piston.

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

I recently had a brake line rupture on an older vehicle that resulted in a potentially fatal near miss. It was a real wakeup call. When I replaced the entire braking system, I decided to pay close attention to every detail and use quality parts. I used this product on every fitting, and unlike Teflon tape, which is arguably an amateur's hack, this is made for the application. Of course, it's for many hydraulic applications, but when a braking system is so critical to your safety, your family's safety, and everyone else's, why mess around? Do it right.
