Frequently asked question (FAQ)

Question: What is the primary function of an O-Ring BR Backup Ring?
Answer: The O-ring BR backup ring is designed to prevent extrusion of O-rings under high-pressure conditions. It supports the O-ring in grooves, ensuring a stable seal even in high-pressure hydraulic or pneumatic systems.
Question: Why is PTFE used for this backup ring?
Answer: PTFE (polytetrafluoroethylene) provides excellent chemical resistance, low friction, and thermal stability, making the PTFE backup ring suitable for use with oils, fuels, water, and various industrial liquids over a wide temperature range (-60°C to +220°C).
Question: How does the backup ring enhance O-ring performance?
Answer: By preventing O-ring extrusion, the BR backup ring maintains proper O-ring deformation and contact with mating surfaces, improving seal longevity and preventing leakage in high-pressure applications.
Question: What pressure ranges are suitable for using a PTFE BR backup ring?
Answer: The O-ring BR backup ring is engineered for high-pressure applications, typically in hydraulic and pneumatic systems where standard O-rings might extrude or deform. Exact allowable pressure depends on O-ring size and groove design.
Question: Can the BR backup ring be used with all O-ring materials?
Answer: Yes. The PTFE BR backup ring is compatible with a variety of O-ring materials including NBR, FKM, EPDM, and silicone. Its chemical inertness ensures no reaction with most elastomers.
Question: What standards does this backup ring conform to?
Answer: This O-ring backup ring conforms to JIS B 2407, ensuring reliable dimensions, tolerances, and performance for industrial sealing applications.
Question: What are the advantages of using a PTFE BR backup ring over other materials?
Answer: PTFE backup rings offer low friction, chemical resistance, thermal stability, and non-stick properties, making them ideal for high-pressure, high-temperature, and chemically aggressive environments compared to nylon or polyurethane backup rings.
