Seals, Washers & Gaskets

The fabrication department at Silex has an extensive range of cutting machinery for gaskets cut from solid and sponge sheet and cutting tubing into washers and sleeves. Excellent tolerance bands on dimensional aspects are guaranteed. 

Silex also manufactures joined seals from extruded sections and cords, together with a variety of special fabrications and assemblies, sometimes incorporating non-silicone items such as valves or connectors.

The Silex portfolio includes hot and cold adhesive bonding, mitre corner bonding and our new film joining technique which uses a thin layer of silicone rubber rather than an adhesive and is bonded under pressure to form a semi-moulded joint which is stronger than adhesive and ideal for curtain wall construction gaskets.

Our technical department is constantly developing new techniques and processes to give the widest choice of possibilities and solutions.
