Permatex 59214 High Temperature Thread Sealant, 6 ml Tube

Sealing my radiator fix with this made me so relieved. I rent and really do not want surprise plumbing issues eating my security deposit. Tube is small but you only use a little, I just squeezed a thin line on the threads and it stopped a slow drip right away. Glad I grabbed it.

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.

Permatex always makes solid products, and this high-temperature thread sealant is no exception. Applies easily, spreads well, and seals exactly as it should. It gives a clean, secure seal and holds up well under heat, which is critical for the types of applications this is used for. I like that it doesn’t make a mess and sets up properly without any issues. Once applied, you can trust it to do its job without worrying about leaks. If you’re working on anything that requires a reliable thread seal under higher temps, this is a great choice. Highly recommend 👍

Good price and quality

Solid product. Consistent results. Good price value

I bought this for small plumbing jobs at my gym, mainly around the break-room water heater. I used it on a threaded fitting during a repair, and it held without a leak when we turned the heater back on. The 6 ml tube is easy to store, but it’s small, and getting the last bit out takes some effort. 🔧

Exactly what it is! Got it fast and no more leaks!

The tube is tiny, but that worked out fine for this one repair. My husband squeezed a little onto the threads, put the fitting back together, and let it sit before using the mower. I liked that he could apply it right where he needed it without making a big mess. We ran the mower later that afternoon, after the kids’ nap, and the fitting stayed put instead of rattling like before. I did keep the tube in a small bag afterward so it wouldn’t get lost in the garage drawer. The 6 ml size makes sense for occasional home repairs, though I wouldn’t count on it for a big project. I’m glad I had it on hand when that mower started making noise again. It saved us another trip to the hardware store, and my husband says he’ll keep the tube with the other repair supplies.

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.
