Product Introduction

This silicone sponge gasket is paired with stainless high-temperature HEPA construction rated on a 260 C basis. It can be fitted upstream, downstream or on both filter faces and used with compatible high-temperature silicone sealants. The gasket is intended for oven and tunnel service where standard polyurethane foam would not retain sealing properties; the full filter, sealant, frame and housing must share the same thermal duty.

Key Features

Heat-resistant compression seal

Silicone sponge maintains resilient contact at temperatures beyond standard cleanroom gasket materials.

High-temperature system compatibility

The profile can be paired with stainless frames and heat-resistant silicone sealants.

Selectable face arrangement

Upstream, downstream or dual-face placement accommodates different oven housing interfaces.

Applications

For depyrogenation tunnels, pharmaceutical ovens and heated process sections where the filter gasket is exposed to elevated operating temperature.

Solutions for Your Application

Only the gasket is heat rated while adhesive or filter sealant fails first.Verify the complete high-temperature assembly, including media sealant, frame, gasket bond and housing compression components.

Repeated heat cycles produce compression set and reduce sealing pressure.Inspect gasket recovery at planned shutdowns and replace the filter when permanent flattening or cracks are visible.

Available Options

Confirm maximum continuous and cycle temperature, profile dimensions, face location, stainless frame, sealant and clamp travel.
