Loctite 565 442-56531 50ml PST Thread Sealant, Controlled Strength, White Color

The Loctite brand of thread sealants are excellent when used properly. This one as well as some of the other loctite anaerobic sealants react in the presence of a metallic catalyst to set up to an excellent sealant. They will not set up when no metal is present so I use copper dust, micron sized and mix it with the sealant when I want a rapid set up or when I use the catalyst acting sealants on some safe plastic fittings that I know from experience are safe for these sealants as they will weaken and destroy some plastics. There are different gripping strengths and set up times available. The high strength sealant creates connections that are very difficult but not imposable to disassemble but this one is medium strength and will set up in about one half hour when a catalyst is used. One downside is they expire and past the expiration date will set up very slowly if at all. I replace my stock every 3 years so that I will not have expired product. The date of manufacture is stamped into the plastic where the tube is crimped at the end. They are anaerobic, set up in the absence of oxygen so the surface may remain liquid where exposed to oxygen but just below the surface they set up as advertised. Excellent products. Learn to use them properly and you will have excellent results and best of all no leaks now or latter.

It did everything it was advertised to do and I have told my friends to use it for all of their sealing jobs.

Received locktite 567, not 565 as listed. Locktite 567 is listed as high temp, low strength.Did not use at this time, keeping for future use.

Worked very well, better than anything I had tried up to that point.

works great
