Frequently Asked Questions

Q: What thread sizes do these PTFE air seal washers fit?

A: These washers are available in M8, M10, and M12 thread sizes, making them compatible with a broad range of pneumatic fittings, air valves, diving regulators, and mountaineering equipment.

Q: Why is PTFE used for air seal washers?

A: PTFE (polytetrafluoroethylene) is an ideal sealing material because it is highly resistant to chemicals, temperature extremes, and physical wear. Its low friction and excellent compressibility allow it to form a reliable, long-lasting seal under high-pressure conditions.

Q: Can these washers be used in diving and pneumatic equipment?

A: Yes — these washers are specifically engineered for high-pressure applications including scuba diving regulators, mountaineering compressed-air systems, paintball markers, and general pneumatic fittings.

Q: How many washers come in a pack?

A: You can choose between a 10-piece pack for lighter use or a 100-piece bulk pack for professional, workshop, or high-volume maintenance needs.
