Bonded Sealing Washers M20 Carbon Steel Nitrile Rubber Gasket M20 Rubber Washer

  • The nitrile rubber is bonded by heat and pressure to the outer ring, which holds it in place. This structure increases resistance to bursting, increasing the pressure rating of the seal (Chicarubber)
  • Materials: Galvanized Carbon Steel; Nitrile Butadiene Rubber: Hardness: 60A; Working Temperature Range: -20°C to 100°C (-4°F to 212°F)
  • Fit for Size: M20; Outer Diameter: 27.8mm; Inner Diameter: 20.7mm; Thickness: 2mm
  • Because the bonded washer itself acts to retain the gasket material, there is no need for the parts to be sealed to be shaped to retain the gasket. This results in simplified machining and greater ease of use as compared to some other seals, such as O-rings
  • The self-centering bonded washers are high-pressure seals that are used in the Mechanical, Hydraulic, and Pneumatic pipelines

The self-centering bonded washers are high-pressure seals that are used in the Mechanical, Hydraulic, and Pneumatic pipelines.

A bonded seal is a type of washer used to provide a seal around a screw or bolt. Consists of an outer annular ring of carbon steel and an inner annular ring of nitrile butadiene rubber that acts as a gasket.

Bonded sealing washers, also known as sealing washers or self-sealing washers, are critical components in various industrial applications, providing a reliable solution to prevent leaks and ensure secure fastening. Among these, the M20 bonded sealing washer, constructed with carbon steel and nitrile rubber (NBR), is a popular choice due to its durability, versatility, and high-performance sealing capabilities.

What is a Bonded Sealing Washer? (Chicarubber)

A bonded sealing washer is a composite washer that combines two materials:

Outer Metal Ring: Provides structural support and ensures proper tightening without deformation.

Inner Rubber Seal: Creates a secure seal to prevent leakage and protect against environmental factors like dust and moisture.

In an M20 washer, the dimensions are tailored to fit M20 bolts, ensuring compatibility with fasteners of 20 mm nominal diameter.
