Rubber Seal Manufacturers Rubber Sealing Washers
Rubber washers are flat rubber rings with center holes to accommodate fasteners or allow fluids to pass through. Rubber washers prevent leaks, protect surfaces, and dampen vibration in a variety of applications. Because of their durability and flexibility, these rubber spacers provide a tighter seal than metal washers in many applications.
Rubber washer uses especially benefit plumbing, heating, ventilation, and air conditioning systems, as well as pools, boats, and other aquatic products that come into extensive contact with water. They also insulate against electric charges in electronic and thermal applications. Additionally, rubber washers absorb shock, making them great for use as rubber spacers in machinery with frequently moving parts. No matter the application, rubber washers' nonabrasive qualities ensure scratch-free products throughout their lifetime.
Rubber Washer Materials and Design
Rubber materials are used because of their high flexibility, pliability, and conformability to different surfaces.
Different rubber washer materials benefit different applications.
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 point oils, but it doesn't work well for petroleum oils and ketones.
Ethylene 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, point oils, and mild acids. Neoprene rubber works well in general-purpose elastomer applications.
