Rubber Sealing Washer - Overview

A rubber sealing washer is a flat, ring-shaped piece of rubber with a hole in the center, designed to create a tight seal and prevent leaks or the passage of liquids and gases. These washers are versatile and used in various applications to prevent leaks, protect surfaces, dampen vibrations, and insulate against electrical charges.

Types of Rubber Sealing Washer

Flat Rubber Washers

Provide a tight seal between two surfaces, preventing leaks in plumbing, automotive, and industrial applications while distributing load and protecting surfaces.

O-Ring Washers

Circular washers with a round cross-section, designed for high-pressure sealing in hydraulic, pneumatic, and mechanical systems.

P-Bonded Rubber Washers

A combination of rubber and metal, offering enhanced strength and durability for high-pressure applications, such as automotive fuel systems and hydraulic connections.

Self-Sealing Washers

Feature an integrated sealing layer, ensuring a leak-proof connection in electronics, HVAC, and waterproof enclosures.

Cushioning & Vibration-Dampening Washers

Designed for shock absorption, reducing vibration, noise, and mechanical stress in machinery, construction, and industrial equipment.

Advantages of Rubber Sealing Washer

Water and Air Sealing

Rubber washers are highly effective in preventing the passage of water or air. This makes them ideal for plumbing, HVAC systems, and applications involving water tanks or pipes.

Chemical Resistance

Certain types of rubber, such as nitrile or EPDM, offer excellent resistance to chemicals and oils. This makes rubber washers suitable for automotive fuel systems, hydraulic systems, and industrial applications where exposure to chemicals is common.

Temperature Resistance

Rubber washers can also perform well in both low and moderate temperatures. EPDM, for example, remains flexible at temperatures as low as -40°C, making it suitable for outdoor applications exposed to varying weather conditions.

General Sealing

For general-purpose sealing in various industries, rubber washers provide a simple, cost-effective solution that is easy to install and replace.

Rubber Washer Sizes

The rubber washers are useful as springs and spacers. They are also used as a wear pad, and locking device. These washers can assist threaded fasteners in the construction field. In compressors, it can seal fluid and absorb vibration.

Following are industries that use a rubber washer:

Plumbing and electrical installation
Construction
Automotive and aerospace manufacturers
Appliance producers
OEMs

Materials and Design

Different rubber washer materials benefit different applications. While rubber washers can be manufactured in a wide variety of materials, most applications use the following washer compositions:

Silicone rubber washers

Silicone washers withstand extreme temperatures (̶150° to 500°F) in dry or humid climates, offering the best overall temperature range available. They also operate with low compression sets and resist ozone, UV light, and fungus. Silicone is the material of choice for brake fluids and high aniline point oils, but it doesn't work well for petroleum oils and ketones.

Ethylene propylene diene monomer (EPDM) rubber washers

These washers can withstand weather extremes and temperatures from ̶60° to 280°F. They also offer low gas permeability and resist ozone, steam, water, alcohols, and brake fluids. EPDM rubber washers have dielectric qualities, which provide excellent protection from electrical currents, ozone, and sunlight. It is heat resistant and has excellent color stability.

Neoprene rubber washers

These washers weather well, have high ozone resistance, and good oil, petroleum, and solvent resistance. They operate in temperatures ranging from ̶65°F to 260°F. They also resist freons, high–aniline point oils, and mild acids. Neoprene rubber works well in general-purpose elastomer applications.

Rubber Washer Sizes
