Formed-In-Place Gasket

Threebond Formed-In-Place Gasket (Engine RTV)

Threebond Formed-In-Place Gasket is a high-performance, temperature-vulcanized silicone RTV designed for reliable sealing of engine components and other critical joints. Engineered to form a flexible, durable gasket in situ, it replaces pre-cut gaskets and ensures a precision fit on irregular or mating surfaces.

• High temperature resistance: Maintains elasticity and seal integrity under extreme engine heat.
• Excellent adhesion: Bonds to metals, aluminum, and many substrates without primers.
• Vibration and oil resistant: Withstands engine vibration, oil, coolant, and automotive fluids.
• Easy application: Smooth bead application, cures to a tack-free, resilient seal.
• Long-lasting durability: Prevents leaks and reduces maintenance downtime.

Ideal for valve covers, oil pans, water pumps, thermostat housings, timing covers, and other engine assemblies. For best results, clean and dry mating surfaces, apply a continuous bead, and allow full cure per manufacturer instructions.

Benefits: Improved leak protection, custom-fit sealing, time-saving installation, and robust performance across a wide temperature range.
