RH Nuttall Limited is a popular, trusted and established UK manufacturer and supplier of all closed cell silicone sponge washers.

Silicone sponge washers are supplied by RH Nuttall to a vast array of different industrial sectors where high temperature sealing is of paramount importance.

Silicone sponge washers are manufactured by RH Nuttall Limited in three different colours, black, white and red (riox).

Applications for silicone sponge washers

Silicone sponge washers are used where high temperature sealing is required. Normally general grades of cellular sponge only take limited temperatures, but you can be sure that silicone sponge will go much higher, even creating an effective seal when exposed to 230 degrees centigrade.

Silicone sponge washers from RH Nuttall are often supplied to heating and boiler manufacturers.

Silicone sponge is a high-end, closed cell, material designed with one function in mind. Silicone sponge washers are used as hob seals, boiler seals, lamp seals and heater seals to stop any transfer of heat from one surface to another.

Compression within the silicone sponge membrane allows for two mating surfaces to be tightened together creating an airtight and efficient seal.
