Rubber washers are flat rubber circles with a hole in the middle. The hole accommodates fasteners or allow fluids to flow through. Round rubber washers are commonly used to prevent leaks, protect surfaces, and reduce the impact of vibrations. Due to their durability and flexibility, rubber spacers are ideal for providing a tighter seal than their metal washer counterparts.
Rubber washers are especially advantageous for applications within plumbing, heating, ventilation, and air conditioning systems, as well as pools, boats, and other products that come into contact with water. In addition, rubber washers also insulate against electric charges in electronic and thermal applications.
Thick rubber washers are commonly used to absorb shock. They make great spacers in machinery with regularly moving parts to prevent damage. Their applications know no limits and their nonabrasive qualities ensure a longer life-span for many machines.
Types of round rubber washer and design
Rubber has great benefits such as high flexibility, pliability, and conformability. These factors make rubber ideal for many jobs. However, different types of rubber benefit different applications. Here is a general overview of rubber washer compositions we have put together.
Silicone washers can withstand extreme temperatures (both hot and cold). This includes dry or humid climates. In addition, they operate with low compression sets and resist elements such as UV light and fungus.
Ethylene propylene diene monomer (EPDM) rubber washers
EPDM washers also withstand extreme temperatures. They resist elements such as ozone, steam, water, alcohols, and brake fluids. Whilst also offering low gas permeability. They are known to have dielectric qualities, which provide protection from electrical currents. In addition, it is heat resistant and has excellent colour stability.
Neoprene rubber washers
Neoprene is another rubber that weathers well and resists oils, petroleum and solvents. In addition it resists freons, high–aniline point oils, and mild acids. Neoprene is a common material in general-purpose elastomer applications.
As a leading rubber washer manufacturer, we have a wide range of round rubber washers and we also offer custom-design washers.
Rubber washer applications
You can use round rubber washers for many things such as spacers, springs, locking devices, and wear pads. They also bear the weight of threaded fasteners, particularly in the construction industry. Not only that, but rubber washers are also excellent at absorbing vibrations within machinery. This can lead to them extending the operational life-span. They are also used to seal fluid.
Industries that commonly use rubber washers include construction, electrical and plumbing installation, aerospace and automotive manufacturers, appliance producers, and OEMs.
