Gasket-Making Adhesives

Gasket-Making Adhesives

Create gaskets of different shapes and sizes with gasket-making adhesives. Also known as formed-in-place gaskets and gasket makers, these adhesives are applied to flanges or between surfaces to fill gaps and holes and form a leak-free seal that keeps fluid, air, or gas in and dirt and contaminants out. They're commonly used on engine components, motor housings, valve covers, gear cases, pumps, and windows.

General Purpose

Use general purpose gasket-making adhesives for everyday sealing tasks that don't require a specialized adhesive.

High Temperature

Seal joints in hot environments and on high-temperature equipment such as motors, exhaust manifolds, ovens, furnace flues, and HVAC ducts with these gasket-making adhesives. They resist cracking and shrinking to keep gaps filled when exposed to high heat.

Adhesive-Backed Cord

Skip the mess of liquid gasket-making adhesives with these soft, flexible cords. Also known as gasket tape, they're made of expanded PTFE, which conforms to fill grooves and gaps between surfaces, and they have an adhesive backing so you can press them into place to form a gasket. Gasket-making cords are typically used to form seals around valves and shafts.
