Permatex 59235 High Temperature Thread Sealant: Locks & Seals Threaded Fittings, Resistant to Leakage, Vibration Loosening, Moisture, Hydraulic Fluids, Diesel Fuels, Easy Assembly and Disassembly 50ml

I’ve used this on air hose ends to seal perfectly and I’ve used this on multiple threads in including turbo oil feeds, oil cooler feeds, oil temp sensor feeds. I really like how it stops threads backing out under vibration too.

Then Motorcycle thermostat thread sealer. Perfect job and easy to use.

Awesome

Does what it says on the tin excellent

Used this on a bleed nipple for a rear brembo brake caliper for a motorcycle Within seconds I was able to bleed the caliper with no air leakage I had spent days rebuilding the caliper numerous times only to have the same problem This sorted my problem in second's Air had been passing by the bleed nipple

Solved a persistent little diesel leak on a compression fitting and much better than using PTFE tape

Does exactly what we needed, recommended

Irritating leak on one cylinder feed on 1959 Massey 35. Hoping this product will cure connection.

Que es muy buen producto

I have applied this seal on thread bolt and left it for almost 80 hours, unfortunately still not dry

Used this for the deadbolts in my engine build and countless other projects where heat and oil are present. Works a treat

Sealed the new PCV in my son's Outback. Stays liquid long enough to be threaded in.

The 6 ml tube looks tiny, but I only needed a little on the threads. I cleaned the fitting, applied the sealant, and tightened it back in place. The next time I checked the car after a short drive, I didn’t see fresh oil around that spot. That was a nice thing to find when I was already tired and ready to sit down. The narrow tube is handy for getting the product where it needs to go, and it didn’t leave me wrestling with a big container in the middle of a small repair. I put the cap back on and stored it with my other car supplies. I’m not someone who enjoys spending my days off chasing little leaks, so having a simple fix on hand made this job less of a hassle. It’s a practical item for occasional garage work, and I’m pleased I had it when that fitting needed attention.
