Made in the USA by Balmar (an Oil Center Research company), HT-1800 combines higher copper content with a stable carrier so it resists burn-off, washout, and mechanical abrasion across the most extreme heat and pressure conditions.\u003c\/p\u003e\n\n\u003ch3\u003eHow does HT-1800 protect fasteners under extreme heat?\u003c\/h3\u003e\n\u003cp\u003eHT-1800 lays down a durable copper barrier that prevents metal-to-metal contact at elevated temperatures so bolts and studs don’t cold-weld or seize.

Liquid-O-Ring HT-1800 is aimed at mechanics, fabricators, marine technicians, performance enthusiasts, and industrial maintenance teams who need a dependable anti-seize for high-temperature, high-pressure, or corrosive environments. If you work on engines, exhaust systems, turbines, or equipment exposed to saltwater and extreme heat and you expect fasteners to come apart later without drama, HT-1800 is formulated for that job.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can HT-1800 be used on spark plugs?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
