Product Description



Jump on a monumental opportunity to buy Back-Up Rings online, crafted for dazzling performance in extreme conditions. Explore our splendid range, available in black, white, blue, and brown, with diameters from 5 mm to 1000 mm. Featuring robust tensile strength (10-25 MPa), exceptional shape retention under high pressure and temperature, and superior chemical resistance (PTFE & FKM). Easy to install and compatible with standard O-rings, these rings are ideal for hydraulic and pneumatic cylinders. Select from split or solid variants, finished smooth/polished, in premium Nitrile, PTFE, Polyurethane, or Viton.

Back-Up Rings: Usage, Advantages & Versatility

Back-Up Rings are engineered for direct placement alongside O-rings in static or dynamic sealing systems, enhancing longevity and preventing extrusion. The advantage lies in their ability to withstand monumental pressure and temperature fluctuations without deformation, ensuring lasting seals. Explore additional applications in hydraulic cylinders, pneumatic equipment, and chemical processing machinery-these rings offer robust support wherever standard O-rings need reinforcement. Adaptable for a wide diameter range and made from resilient materials, Back-Up Rings are a splendid solution for demanding sealing challenges.

FAQ's of Back-Up Rings:


Q: How are Back-Up Rings installed with standard tools?

A: Back-Up Rings are designed for easy installation. Simply position the ring adjacent to the O-ring within the sealing groove, using standard tools to seat both components securely. This method effectively reinforces the seal under pressure.

Q: What is the benefit of using Back-Up Rings in hydraulic systems?

A: The primary benefit is exceptional shape retention under high pressure and temperature, preventing O-ring extrusion. This prolongs equipment life and ensures leak-proof operation in critical hydraulic and pneumatic systems.

Q: When should I use split versus solid Back-Up Rings?

A: Split Back-Up Rings are ideal for situations where disassembly is difficult or where installation space is limited, while solid types are best when maximum integrity and robustness are required.

Q: Where can Back-Up Rings be applied besides hydraulic cylinders?

A: Aside from hydraulic and pneumatic cylinders, Back-Up Rings are suited for static and dynamic sealing systems, chemical processing machinery, and applications involving fuels, oils, water, and gases.

Q: What materials are available for Back-Up Rings and why choose them?

A: You can choose between Nitrile Rubber, PTFE, Polyurethane, or Viton (Fluorocarbon). Selection depends on media compatibility, working conditions, and desired chemical or temperature resistance.
