Sealing Washers
Sealing washers are specialized washers designed to prevent leakage of fluids or gases at the joint between two surfaces. They're typically used in plumbing, automotive, hydraulic, and pneumatic systems where a tight, leak-proof seal is critical.
Features of Sealing Washers:
Sealing washers are specialized washers designed to prevent leakage of fluids or gases by creating a tight seal between joined surfaces. They are commonly used in plumbing, automotive, hydraulic, and pneumatic systems. Seal and cushion seal gaps and also help absorb vibrations or movement between components. Commonly used where bolts, screws, or fasteners pass through surfaces carrying liquids or gases.
Sealing washers are Often made from or bonded with rubber (like neoprene, nitrile, or silicone), metal (aluminum, copper, stainless steel), or composite materials. They are Usually flat and round, with a hole in the center for the bolt or screw but can vary depending on the application.
Rubber or composite sealing washers can absorb vibrations, reducing loosening or damage over time. It can be made to withstand high pressures and temperatures, depending on material choice. They are Corrosion Resistance and materials like stainless steel or coated options resist corrosion, making them suitable for harsh environments.
Sealing washers can be installed like regular washers but provide an extra sealing function without the need for additional sealing compounds.
Types of Sealing Washers:
Bonded Sealing Washers (e.g., Dowty washers): Metal outer ring with a bonded rubber inner ring – excellent for high-pressure environments.
Rubber Sealing Washers: Fully rubber for flexible and non-metal surfaces. Made from neoprene, EPDM, or silicone. Great for water, oil, and low-pressure sealing. Often used in plumbing and HVAC systems.
Copper or Aluminum Crush Washers: Lightweight and corrosion-resistant. Deform slightly to fill gaps and create a seal often used in automotive brake and oil systems. Seals well under compression, often used in engine and transmission systems.
Fiber or Nylon Washers: Used in low-pressure or electrical applications. Made from cellulose, resin, or aramid fiber. Good chemical resistance; used in fuel systems and oil lines.
PTFE (Teflon) Washers : Chemically inert, excellent for corrosive environments. Low friction; common in chemical
Processing equipment
Flat Sealing Washers : Basic design, used for sealing between flat surfaces.
Conical or Beveled Washers : Provide better sealing in high-pressure fittings with non-parallel surfaces.
O-Ring Washers : Integrate an O-ring into the washer design for dynamic sealing applications.
Shoulder Washers (Insulating Washers) : Often used for electrical insulation but can be designed to provide sealing too.
Applications for Sealing washers :
Plumbing and Pipe Fittings: Plumbing connections (like faucets and pipe fittings). Prevents water leakage in high and low-pressure systems.
Hydraulic systems: Common in engines, fuel systems, and brake systems. Automotive (oil drain plugs, fuel systems). Ensures tight seals in oil pans, valve covers, and transmission pans.
Aerospace and marine industries: High-performance sealing washers are used in aircraft hydraulic and fuel systems. Must withstand extreme temperatures and pressures.
Mechanical Assemblies: Used in bolted joints to prevent fluid or gas leakage. Helps maintain consistent pressure and tightness.
HVAC Systems: Seals connections in heating, ventilation, and air conditioning systems. Prevents refrigerant and air leaks.
Industrial Equipment: Used in pumps, compressors, and valves. Protects equipment from leaks that could lead to failures.
Electronics and Electrical Enclosures: Sealing washers with rubber or silicone elements prevent dust and moisture ingress. Used in outdoor equipment, sensors, and junction boxes.
Chemical and Food Processing: Ensures sanitary and leak-proof connections. Must often be resistant to corrosion and compatible with process fluids.
Appliances: Found in washing machines, dishwashers, and water heaters. Prevent leaks and maintain pressure within water-handling components.
