RH Nuttall Limited produce silicone washers, silicone gaskets, silicone seals, silicone strip and silicone sheet for a variety of different industrial sectors.

Silicone rubber is generally used by RH Nuttall for applications including medical, insulation, fire stops, plumbing and building. From simple silicone washers or silicone sheet, to more complex and bespoke silicone gaskets or silicone strip, RH Nuttall Limited has the answer.

Thicknesses of silicone washers, silicone gaskets, silicone strip and silicone sheet can vary from 0.5mm, 0.8mm, 1mm, 1.5mm, 2mm, 3mm, 4mm, 5mm, 6mm, 10mm, 20mm. Custom made silicone can be produced to gain any non-standard thickness that is required, but minimum order quantities are applicable.

Our silicone rubber sheet, silicone rubber strip, as well as silicone rubber gaskets are all available in both white and black colours. A self-adhesive backing can be applied to most silicone rubber products we supply.
