Permatex ウルトラレッド 高温ガスケットメーカー 3オンス

Needed a quality product to seal a pass-through thermocouple in my electric smoker. Works perfectly.

Excellent

I used the Permatex Ultra Red 81630 on a high-heat automotive application, and it performed exactly as expected. It spreads easily, creates a strong, flexible seal, and handles high temperatures without cracking or shrinking. The curing process was straightforward, and once fully cured, it provided a leak-free seal. It's perfect for exhaust manifolds, headers, turbo components, and other high-temperature areas. The 3 oz tube is easy to use and provides enough material for several repairs. I would definitely buy it again for future automotive projects.

Good quality at a fair price.

Trust this tube if your shop runs hot. I grabbed it for my espresso machine and a cranky space heater in the lobby. This stuff sticks, cures fast, and doesn’t stink up the front desk. I squeezed a thin bead, bolted things back together, and went right back to customers.
