Basic Information

Type O-Ring Types P (for Motion / Fixing)

Frequently asked question (FAQ)

Question: Please tell me when to replace the O-ring and its lifespan.
Answer: It depends on its material & the usage conditions, so we cannot answer the question of lifespan.
Question: Can I reuse the O-ring I removed once?
Answer: No. Make sure to replace it with a new O-ring.
Question: What should I be careful about when storing O-rings?
Answer: When storing O-rings, please be aware of the following:
•Do not open the packaging unnecessarily, as this may result in foreign objects or dirt adhering to the ring or scratches.
•Store in a low humidity area away from direct sunlight.
•Do not store near a high-temperature heat source.
•Do not hang the ring on a nail or string.
Question: What is the storage period for O-rings?
Answer: This applies to O-rings stored in a sealed package in a warehouse away from direct sunlight, high temperatures, and high humidity.
•NBR: 10-year
•Silicone Rubber (VMQ): 20-year
•FKM: 20-year
•EPDM: 20-year
Question: Can JIS B 2401 P Series O-Rings be used with aggressive chemicals?
Answer: Yes, but material selection is crucial:
•FKM (Viton®) is highly resistant to fuels, solvents, and aggressive chemicals.
•NBR is suitable for petroleum-based fluids but not strong acids or ozone exposure.
•VMQ (Silicone) is used in applications requiring high-temperature resistance but has poor resistance to petroleum-based fluids.
Question: Are JIS B 2401 P Series O-Rings compatible with hydraulic and pneumatic systems?
Answer: Yes, these O-rings are widely used in hydraulic cylinders, pumps, and pneumatic actuators to prevent fluid and air leaks.
