Product Introduction

The EPDM gasket is a continuous extrusion intended to sit in a compatible door-frame groove. Its projecting lip bends against the closing leaf, creating contact through elastic deformation rather than an inflated chamber. The profile can be cut and joined to follow the perimeter of the opening. This component is selected by its cross-section and fit with the frame, allowing worn seals to be replaced without changing the complete door assembly.
