Loctite LOC59875 Rtv Silicone Gasket Maker 300 Ml

Product Description

The LOCTITE LOC59875 is a high-performance RTV silicone gasket maker designed for use on aluminum, iron, and steel flanged mating surfaces. Supplied in a 300 ml cartridge, this non-corrosive, anaerobic-cure compound forms a flexible, durable gasket in place, eliminating the need for pre-cut gaskets on many common flange configurations. It is suited for on-the-spot and emergency repairs in HVAC, plumbing, and industrial maintenance applications. Licensed technicians and maintenance professionals reach for this product when standard gasket stock is unavailable or when sealing irregular or slightly warped flanges.

This gasket maker is commonly applied to residential and commercial equipment flanges, including engine covers, gear housings, valve covers, and similar mating surfaces found in mechanical and HVAC service environments. Its compatibility with aluminum, iron, and steel makes it a versatile choice across a wide range of service calls. The 300 ml cartridge format is intended for use with a standard cartridge dispensing gun, allowing controlled application in the field or shop.
