What is a BRT Hydraulic Seal?

BRT stands for Backup Ring with PTFE and it is a type of hydraulic seal designed for reliable performance in harsh operating environments.
A BRT seal is made from a combination of Nitrile Rubber (NBR) and PTFE (Polytetrafluoroethylene).

• PTFE offers a durable, low-friction surface with excellent wear resistance.

• NBR, on the other hand, provides flexibility and resistance against oil, grease, and hydraulic fluids.

Technical Specifications of BRT Seals

• Material: Nitrile Rubber (NBR) + PTFE

• Temperature Range: -40°C to +100°C (-40°F to +212°F)

• Pressure Range: 0 – 50 MPa (up to 7,250 psi)

• Operating Speed: up to 20 m/s (66 ft/s)

Applications of BRT Seals

BRT hydraulic seals are widely used in construction machinery and heavy-duty equipment that operate under high pressure and exposure to contaminants.
For example, you can find them in excavators, bulldozers, and backhoes.
In addition, they are also used in wheel loaders, skid steer loaders, and cranes.
Moreover, they play an essential role in concrete mixers and asphalt pavers, ensuring smooth and safe operation.

Key Benefits of BRT Hydraulic Seals

• Superior sealing performance even in extreme conditions

• High wear and tear resistance leading to longer service life

• Versatility for a wide range of hydraulic applications

• Durability against high pressures, speeds, and temperatures

• As a result, they help reduce downtime and lower maintenance costs
