RUBBER WASHER , Model Name/Number: RUBBER WASHER

  • (Customer Reviews)
Overview

A rubber washer is a versatile component used across various industries to provide sealing, vibration damping, noise reduction, and load distribution. Made from different types of rubber, these washers are essential in plumbing, automotive, industrial, and aerospace applications.

In the world of sealing and industrial hardware, a Rubber Washer is a flat ring made of an elastomeric material. While it looks simple, its primary "feature" is its ability to act as a gasket—deforming under pressure to create a liquid or airtight seal between two flat surfaces.

Material Key Property Common Use
Neoprene All-purpose durability Weather stripping, general plumbing, and outdoor seals.
EPDM UV & Steam resistance Outdoor solar heat systems, automotive window seals, and steam lines.
Nitrile (Buna-N) Oil & Fuel resistance Fuel line connectors, hydraulic tank lids, and engine gaskets.
Silicone High heat & Food safe Kitchen appliances, medical devices, and high-temp oven seals.
Viton (FKM) Chemical "Armor" Chemical processing plants and high-performance fuel systems.

 

·  Durometer (Hardness): Easy to compress; great for low-pressure plastic fittings.

  • Hard (70--90 Shore A): Required for high-torque bolting applications to prevent the washer from "squishing" out of the sides.

·  Compression Set: This is the "memory" of the rubber. A high-quality washer will return to its original thickness after being loosened. Low-quality rubber will stay flattened, leading to leaks if the bolt is ever re-tightened.

·  ID / OD / Thickness: * ID (Inside Diameter): Must fit snugly around the bolt or pipe.

  • OD (Outside Diameter): Must be large enough to cover the sealing surface but small enough to fit in the housing.
