What are Rubber Washers?

Rubber washers are simple yet essential parts in many engineering projects that require vibration dampening and a water-tight fit. Renowned for their durability and flexibility, these flat rubber discs are placed between two surfaces, like a bolt and a piece of metal.

Their primary function is to act as a sealing barrier, although they also distribute the load, absorbing shocks and vibrations, to help ensure that the screw stays tight and secure. Whether they're used in a bike, a washing machine, or even in a space shuttle, rubber washers play a vital role in keeping liquids where they should be and preventing parts from getting damaged.

How Rubber Washers Work

Rubber washers are versatile and find their use in various industries, from automotive to aerospace. They're particularly effective in scenarios demanding vibration dampening and shock absorption.

For instance, in plumbing systems, rubber washers for screws are essential for creating watertight seals, preventing leaks in pipes and faucets. In electrical applications, these washers serve as insulators, protecting components from electrical surges. Accu's range, from 1 rubber washer to bulk quantities, caters to both small-scale projects and large industrial needs.

Material Composition

Accu's choice of material for these washers is TPR Rubber, known for its resilience and environmental resistance. This material choice makes them ideal for outdoor applications, as they withstand weather elements effectively. The variation in rubber washer sizes and materials ensures suitability for different environments.

Sizes and Types of Flat Rubber Washers

Accu offers a comprehensive range of sizes, from small rubber washers designed to mate with M3 (3mm) thread size for delicate applications to rubber penny washers up to M20 (20mm) for more robust needs. The external diameter varies from 7mm to 50mm, catering to different scale requirements. Thicknesses range from 0.5mm, suitable for tight spaces, to 3mm for more demanding scenarios.

If you find our range doesn't exactly suit your needs, Accu prides itself on offering custom manufacture of any component, so get in touch with our engineers if you need custom rubber washer sizes.

FAQs

Q: What are rubber washers used for?

A: Rubber washers are used to prevent leaks, distribute load, reduce vibration, and provide insulation in various mechanical and electrical applications.

Q: Do rubber washers prevent leaks?

A: Yes, when properly installed, they are excellent at preventing leaks, particularly in plumbing systems.

Q: What is the difference between a rubber washer and a rubber gasket?

A: Rubber washers are generally thinner and used for load distribution and spacing, while rubber gaskets, which can be made of rubber or other materials, are specifically designed for sealing between two surfaces. Washers typically are always cylindrical whereas gaskets can be made to any shape or size.

Q: How do I choose the right size for my project?

A: Consider the thread size of the bolt or screw (ranging from M3 to M20), the required external diameter (7mm to 50mm), and the thickness needed (0.5mm to 3mm) based on the application.

Q: Is TPR rubber suitable for outdoor use?

A: Yes, made from TPR rubber, Accu's range is resilient and resistant to environmental factors, making them suitable for outdoor applications.
