High Temperature Silicone

High Temperature Exhaust Silicone

High temperature silicone is essential for sealing and assembling exhaust components where heat resistance and flexibility are critical. Ideal for use on slip joints, flanges, and gaskets, this RTV-style silicone withstands extreme exhaust temperatures and creates a gas-tight seal.

Our high temp silicone is sensor-safe, easy to apply, and resistant to vibration, pressure, and thermal cycling. It’s perfect for both professional and DIY use in street cars, 4WDs, and performance builds.

Use in conjunction with flange gaskets, exhaust clamps, or flex joints to reinforce sealing and prevent exhaust leaks under load.

It’s also a go-to choice for custom exhaust fabrication using pipe & tube and mandrel bends, where thermal movement and vibration are common.
