Excellent Sealant for Automotive Use!
used it to seal the differential plugs on my Ram 1500. It worked perfectly! The application was smooth and easy, and it provided a strong, leak-proof seal that gives me peace of mind. I really appreciate that it’s designed for high-temperature environments, which is essential for automotive applications. After driving for a while, I’ve had zero leaks and everything is holding up great. The tube size is convenient and has plenty of product for multiple uses. If you need a reliable, high-performance thread sealant for your vehicle, this is an excellent choice. Highly recommend for anyone doing differential or drivetrain work!

Useful sealant for high-temperature jobs
I found this Permatex thread sealant really helpful when working on engine parts. it’s small but goes a long way and keeps leaks tight under heat. I’ve used it during repairs in my garage, and it’s stayed durable. works well and I’m glad I chose it.

If you need it, you need it!
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 👍

Works well but very little product in 6ml tube.
Product seems to work fine. However, I purchased the small (6ml) tube and I could barely squeeze out two drops to seal a temp sender. This tube DEFINITELY did not contain 6ml. Otherwise I would have given it 5 stars as I like better than tape.

Useful thread sealant for_engine repairs
Operating on my engine, I applied this Permatex sealant to ensure those fittings stayed leak-free even when things heat up. It’s a small tube, but I’ve used just a little each time and it lasts. The durability during my garage repairs has been good, and I’m pleased with how well it performs. Definitely a handy product to keep around.

Works as expected. No leaks after a short setting and curing period. Used it to seal an oil pressure sensor. Heat resistant

スポーツスターのオイルドレン用に購入しました。テープは、巻く方向やカスが気になる為こちらの商品を使用しワッシャーも新品使用で作業しましたが漏れもなく問題ありません。
