Bonded Sealing

Bonded sealing washers combine a durable metal outer with a bonded rubber sealing layer to deliver both strength and watertight performance. The metal face provides structural support and load distribution, while the rubber insert compresses under fastening to create a tight, weather-resistant seal.

These washers are widely used in roofing, cladding, and external fixings where protection against water ingress, UV exposure, and temperature fluctuations is critical. EPDM-bonded options are particularly valued for their long service life and resistance to environmental degradation.
