Different types of seals function differently in various industries. Machinery is made to work using various sorts of pressures. To seal those pressure well, bonded seals are available in the market. These consist of a rubber sealing inside of metal Viton ring. Actually, the bonded rubber seals were designed to replace copper type washers which are used to deteriorate by time.
Metal Viton is the element that is bonded to the outer wall of a rubber seal. They are useful in a function where there is high pressure and they demand greater sealing capacity that can be obtained with Copper washers.
Rubber bonded seals are also known as Dowty seals or Dowty bonded washers as they are high-pressure seals. These are used in the
- Mechanical
- Hydraulic and
- Pneumatic Sectors
Structure description of bonded seals
A metal Viton rubber bonded seal is a type of washer used to deliver a seal around a screw or bolt. Now widely manufactured and supplied by leading metal Viton rubber bonded seals suppliers, they are available in a range of standard sizes and materials
This type of seal consists of
- An outer annular ring of a hard material, typically metal Viton, and
- An inner annular ring of an elastomeric material typically nitrile rubber acts as a gasket
It is the firmness of the rubber part between the faces of the division on either side of the bonded seal that presents the sealing action. The elastomeric material is bonded with heat and pressure to the outer ring. This simply holds it in place. This structure amplifies resistance to bursting, escalating the pressure rating of the seal.
Patterns available
As the bonded seal acts itself to retain the gasket material, no need for the parts to be sealed to be shaped to retain the gasket. Some designs come with an added flap of rubber on the inner diameter to place the bonded seal at the center of the hole. These are known and available as self-centering bonded washers.
These self centralizing lip bonded seals are available with or without the lip. The specific features:
- Eliminate Seal Offset
- Eliminate Leaks
- Ease of Installation
- Reduce Assembly time
- Captive Assembly
Characteristics of metal Viton rubber bonded seals
- Ideal Pressure Gasket.
- Reliable sealing at high & low pressure.
- High & low-temperature capability.
- Reduced bolt torque with no loss of tightening loads.
- Metal ring prevents rubber compression.
The most common seal types available with the metal outer ring are Mild Steel, Stainless steel or metal Viton rubber bonded seals. Other more unusual metals can be supplied. So the suppliers make use of different combinations of metal and rubber sealing elements to produce highly resilient seals.
Bonded Seals are available in an option of metals including:
- Mild Steel
- Nitrile
- Stainless Steel
- Viton
- Brass
- EPDM
- Aluminum
- Silicone
