Frequently Asked Questions
Q: What pipe sizes do these copper reducing couplings connect?
A: These couplings connect a 22mm (3/4") pipe to a 16mm (1/2") pipe, making them ideal for reducing pipe diameter in HVAC, refrigeration, and hot water systems.
Q: Are these copper reducing couplings compatible with all copper pipe types?
A: Yes — they are designed to work with M-type, L-type, and K-type copper pipes, providing broad compatibility for both residential and commercial plumbing applications.
Q: What is the maximum operating pressure for these fittings?
A: These copper reducing couplings are rated for operating pressures below 850 kPa, which covers the requirements of most standard HVAC, refrigeration, and hot water systems.
Q: How are the connections made — do they require soldering?
A: The couplings use a socket-style connection that is designed for welding/soldering (brazing). This ensures a fully leak-free, secure joint suitable for high-reliability installations.
