Flat Rubber Washer Specs
Flat rubber washers are pieces of rubber, usually in the shape of a ring or a circle with a hole in the middle. They are often used, and if you were to take a look around your household, we are certain you would find at least a dozen of them. More often than not, flat rubber washers are used to help create a better seal or accommodate fasteners. Also, they can be used to prevent leakage or spills. Furthermore, if you need to protect gentle surfaces and possibly dull the vibrations – flat rubber washers can be quite helpful.
Since there are so many applications across various fields, it is important to understand the characteristics and specifications of rubber washers, so here are some of the most important flat rubber washer specs.
When it comes to the sizes of flat rubber washers, there are several factors to consider. You should take a look at the internal diameter, outside diameter, thickness, colour, and arguably one of the most important flat rubber washer specs – material.
We have been manufacturing flat rubber washers for quite a long time, and we know how the material from which the washer is made of can affect the quality and application of the washer. For instance, a silicone flat rubber washer is ideal if you need a washer that can withstand both really low and really high temperatures and also offer great isolation and resistance to both weather conditions and chemical substances. EMPD rubber washers, on the other hand, can withstand temperatures slightly less intense than silicone, but they provide excellent dielectric properties, making them suitable for different applications. Finally, neoprene rubber washers can also withstand some low and high temperatures, but they are the best for when you need an oil and petroleum resistant rubber washer that can also resist freons and mild acids.
Product specifications
- Product form
- Rubber washer at a clamped joint
- Material options discussed
- Silicone and chloroprene rubber (CR). Choose one formulation for the actual contact and loading conditions.
- Dimensions to confirm
- Inside diameter, outside diameter and uncompressed thickness.
- Contact conditions
- Lubricating oil and acids: define concentration, temperature and contact time, then check compatibility with the chosen compound.
- Exposure to evaluate
- Outdoor weather and oil splash. Validate the selected material under the combined conditions.
- Clamped condition
- Define the assembled gap and compressive load so the washer is not over-compressed.
