1. 【High-Quality Material】: The check valve is made of brass and galvanised on the outside. It is forged at high temperatures, has a reinforced wall thickness and is corrosion and break-resistant. This significantly extends the service life of the check valve and reduces leaks 2.【Wide Application】: The brass intermediate valve is suitable for drinking water pipes, water heaters, shower pipes, toilets, air conditioning systems, radiators, underfloor heating systems and small drainage pumps 3.【Package Includes】: The package includes a 3/4-inch brass check valve with external thread, a 3/4-inch brass check valve with internal thread, a 3/4-inch brass check valve with two external threads and 3 seals with an internal diameter of 15 mm 4.【Reliable Sealing】: Brass is a material with good mechanical strength and toughness. This allows the check valves made from it to withstand high working pressures. The valve body does not deform or break easily, ensuring stable operation. It is not damaged by impacts. These properties make it particularly suitable for use in environments with unstable pressure, such as in the water supply of high-rise buildings and in industrial circulation systems 5.【Easy Installation】: The compact, lightweight brass check valve can be installed directly into the piping system via threaded connections without the need for complicated tools. During routine maintenance, minor leaks or blockages can be remedied by cleaning the valve flap and valve seat of contaminants or replacing worn sealing rings. The entire valve does not need to be replaced for this
