Frequently Asked Questions

Q: What thread standard does this copper ball valve use?

A: This mini ball valve uses the PT (pipe taper) thread standard, available in sizes 1/8", 1/4", 3/8", and 1/2". PT threads are tapered and commonly used in water and gas pipe fittings to create a leak-resistant seal without additional sealant (though PTFE tape is recommended for best results).

Q: Is this ball valve suitable for gas lines?

A: Yes. The copper mini ball valve is designed for use with both water and gas lines, and it supports operating pressures of up to 850 kPa. Always ensure correct installation and check local codes and regulations before use on gas systems.

Q: What does "double inner and outer wire teeth" mean?

A: This refers to the valve having both male (outer) and female (inner) threaded ends, allowing it to connect to a wide range of pipe fittings and configurations without needing additional adapters.

Q: How do I operate the ball valve?

A: Simply turn the lever handle 90 degrees (quarter-turn) to open or close the valve. When the handle is parallel to the pipe, flow is open; when perpendicular, flow is closed — making it quick and intuitive to operate.
