Rubber washers and spacers are flat rubber rings with center holes to accommodate fasteners or allow fluids to pass through. Rubber washers and spacers prevent leaks, protect surfaces, and dampen vibration in a variety of applications. Because of their durability and flexibility, these rubber washers and spacers provide a tighter seal than metal washers in many applications.
Rubber washers and spacers are used for a variety of industries including 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 and spacers absorb shock, making them great for use as rubber spacers in machinery with frequently moving parts.
Hebei Shida Seal Group manufactures weather-resistant rubber washers and spacers, oil-resistant rubber sealing washers with EPDM, Silicone, Buna-N/Nitrile, FKM, Natural Rubber, etc.
Ethylene Propylene Diene Monomer (EPDM) – Excellent weatherability, good high and low temperature resistance, low gas permeability. Resistant to ozone, steam, water, alcohols, brake fluids. Poor resistance to petroleum oils, diester lubricants. Temperature range: -60°F to 280°F.
Buna-N/Nitrile – Excellent resistance to petroleum products, excellent compression set; resistant to oil, water, silicone greases and oils. Not recommended for halogenated hydrocarbons, ketones, ozone and sunlight. Temperature Range: -65°F to 275°F.
Silicone – Best overall temperature range of elastomers currently available. Excellent resistance to dry heat, as well as, resistance to low temperature, brake fluids, high aniline point oils. Not recommended for some dynamic applications due to poor tensile strength and tear. Poor in petroleum oils and ketones. Temperature range: -150° to 500°F.
FKM– Outstanding resistance to the effects of heat, chemicals, and solvents. FKM has good tensile, resistance and low compression set. Limitations include poor low-temperature properties, limited hot-water resistance and shrinkage. Temperature range: -50° to 600°F.
