Bonded Seals We offer a comprehensive range of Bonded Seals which is widely used for the high pressure resistance applications. These are compatible with the mineral oils, bio oils, water soluble & water glycol fluids and can operate in 1000 BAR pressure. These are manufactured using NT5/b with metal ring but can also be provided in stainless steel as per the specifications provided by the clients.
Material:
- NT5/b with metal ring
- Spareage NT5/b is a Acrylonitrile Butadiene Compound (NBR) of shore hardness 85O
- (The standard material is NT5/b but fluro Rubber +200OC with stainless steel is also available on request)
Maximum Operating Conditions:
- Temp: 0OC to 100OC (upto + 200OC on request)
- Pressure: 1000 BAR
Compatibility:
- Mineral oils
- Oils
- Water soluble
- Water glycol fluids
Applications:
- General purpose seal
- High Pressure resistance applications
Details:
- The Spareage style BS seal is a bonded seal combination of NBR seal ring and a metal back up ring
- The NBR seal ring is bonded perfectly to the inner portion of the metal back up ring
- When a bolt is tightened with BS seal, the NBR seal ring having a Trapezoidal Cross section gets compressed to an extent where the bolt cannot be further tightened due to the metal back up ring
- Under such state, the NBR seal ring not only has a pre-load pressure on the mating surface higher than the pressure being sealed, but also forms the profile of a U-ring to withstand higher pressures
- The BS seal can also be provided in high temperature resistant material on request
Features:
- High pressure resistance
- Metal back up
- Most suitable profile
- Standard dimensions
