EPDM Bonded Washer

Product: Aluminum EPDM Bonded Sealing Washer

Metal: Galvanized Steel G60 (Z12), G90 (Z27), Aluminum, Stainless Steel (A2)

EPDM heat resistance for 20 minutes:
Black non-conductive EPDM: 170 degrees Celsius (338 Fahrenheit)
Grey EPDM: 150 degrees Celsius (302 Fahrenheit)
Black conductive EPDM: 220 degrees Celsius (428 Fahrenheit)

EPDM Hardness: customization is available, Black / Grey non-conductive EPDM: 75 +/- 7 degrees shore A, Black conductive EPDM: 70 +/- 5 degrees shore A


EPDM properties are its outstanding heat, ozone, and weather resistance.
Quality elastomeric compounding to meet specifications for elasticity, memory, temperature extremes, chemical, ozone, and sunlight resistance. It has the ability to retain a light color. EPDM’s benefit is not to pollute the runoff rainwater.
Conical design directs the flow of facing materials to form a seal conforming to both fastener and sealing surface
Reliable sealing quality for the diverse screws. (Roofing, self-taping, self-drilling, tank, slot screws….)
Excellent conductive performance for powder painting screws.
Reduce the failure painting risk.

Bonded washer manufacturer – a simple pressure gasket providing leak-proof sealing from water, gasses, oils, and other fluids. EPDM rubber has vulcanized the metal from the zinc plated mild steel, aluminum, and stainless steel. Bonded washers are a cost-effective solution for roofing screw connections.

2.Application of washers bonded with EPDM rubber:

Washer with EPDM gasket structurally consists of two elements – steel washer and gasket made of ethylene propylene diene monomer, one of the types of synthetic weather-resistant durable rubber EPDM, which has high elasticity and stable consistency during pressing.

The advantages of using weather-resistant rubber EPDM as a sealing gasket are indisputable in comparison with simple rubber:

  • EPDM rubber is very flexible and does not flow at the pressure. Due to this, the gasket does not flatten forcibly under the pressure washer.
  • EPDM gasket does not change its shape over a long period of time, which ensures perfect tightness.
  • Gasket made of EPDM fits noticeably better even when screwing in the roofing screws at an angle.
  • EPDM contains no sulfur compounds and therefore resistant to ultraviolet radiation.
  • EPDM’s benefit is not to pollute the runoff rainwater.
  • Sealer EPDM has minimal temperature deformation and retains basic performance in the temperature range of −40°C … +90°C. Even if the gasket freezes or overheats, its elasticity and flexibility will remain in its original form as opposed to conventional rubber.

The EPDM gasket is firmly anchored to the steel washer by vulcanizing. The steel part of the washer has an annular shape and is slightly concave, which allows the fastener to adhere securely to the base surface and not to spoil the substrate.

Such washers are designed to strengthen and seal the fixing unit. Bonded washers are a cost-effective solution for roofing screw connections. The most common area of application – the attachment of roll and sheet materials for external, such as roofing, work.
