What is a Metal Bonded Rubber Washer for M12?
A metal bonded rubber washer for M12 is a washer designed with a combination of metal and rubber. The metal washer typically provides structural strength and durability, while the rubber component, bonded to the metal, offers flexibility, vibration damping, and sealing properties. It is designed specifically for M12 size bolts, with a diameter of 12mm.
-
What are the key features of a Metal Bonded Rubber Washer for M12?
Key features include enhanced sealing capabilities, resistance to corrosion, vibration absorption, and durability. The metal provides strength, while the rubber acts as a cushion, helping prevent wear and tear and offering protection against shocks or vibrations.
-
What materials are typically used for the metal and rubber components?
The metal is usually made from stainless steel, carbon steel, or alloy steel for strength and corrosion resistance. The rubber is typically made from materials like EPDM, Neoprene, Nitrile, or Viton, depending on the application’s specific needs (e.g., resistance to heat, chemicals, or pressure).
-
What are the main applications of Metal Bonded Rubber Washers for M12?
These washers are used in a wide range of applications including automotive, industrial machinery, plumbing, and electrical systems. They are particularly useful in applications that require a combination of sealing and vibration dampening, such as in engine components, hydraulic systems, and high-pressure assemblies.
-
How do Metal Bonded Rubber Washers help with sealing?
The rubber layer in a metal bonded rubber washer forms a tight seal between components, preventing leakage of liquids, gases, or other substances. This makes them ideal for use in high-pressure or fluid-based applications like pipes, valves, or tanks.
-
What benefits do Metal Bonded Rubber Washers provide compared to standard rubber or metal washers?
Metal bonded rubber washers offer the combined benefits of both metal and rubber. The metal provides strength and structural integrity, while the rubber offers better sealing, shock absorption, and vibration dampening compared to traditional metal washers. This combination also reduces the risk of surface damage and corrosion.
-
Can Metal Bonded Rubber Washers for M12 withstand extreme temperatures?
Yes, depending on the rubber material used, these washers can withstand a wide range of temperatures. For instance, EPDM can handle temperatures between -40°C to 120°C, while Viton rubber can withstand higher temperatures up to 200°C. It is important to choose the right rubber material based on the temperature range of your application.
-
Are Metal Bonded Rubber Washers resistant to chemicals?
Metal bonded rubber washers can be resistant to a variety of chemicals, depending on the rubber type. Nitrile rubber offers resistance to oils and fuels, while EPDM is better for water, steam, and some chemicals. If chemical resistance is important, selecting the correct rubber material is crucial for ensuring performance.
-
How does the bonding of metal and rubber improve washer performance?
The metal and rubber are bonded together through a process that ensures a secure, long-lasting connection. This bonding prevents the rubber from slipping off the metal, maintaining the washer’s integrity under pressure or movement. The bond ensures the washer performs as a unified component for both sealing and cushioning.
-
What industries benefit from using Metal Bonded Rubber Washers for M12?
Industries such as automotive, aerospace, manufacturing, construction, and plumbing benefit from using metal bonded rubber washers. They are particularly effective in machinery, pumps, engines, HVAC systems, and any application that requires both sealing and vibration resistance.
