A Sanha 22mm Copper Press Gas Coupling is a type of plumbing fitting used for connecting copper pipes used in gas installations. The coupling is designed to be used with a press-fit system, which involves using a special tool to compress the fitting onto the copper pipe, creating a tight, leak-proof seal.

The Sanha 22mm Copper Press Gas Coupling is specifically designed for use in gas installations, which require fittings that can withstand high pressure and meet strict safety standards. The coupling is made from high-quality copper and is designed to be corrosion-resistant and long-lasting.

It is important to note that the use of plumbing fittings in gas installations should only be performed by qualified professionals who are trained in the proper installation and safety procedures. Incorrect installation of gas fittings can lead to serious safety hazards, including fire, explosion, and carbon monoxide poisoning.
