Fittings
End cap
End caps act as protective device and are designed to protect pipe ends of various shapes. The main purpose of using pipe caps is to waterproof the connections. They are also used to close the ends of hydraulic or pneumatic pipes and tubes. They are used in the plumbing apparatus of domestic, commercial and industrial water supply lines, machinery and processing equipment etc. They are also fitted on water pump lines with the sole purpose of removing air blocks. Pipe caps are highly demanded as an important category of pipe fittings.
Foot valve
A foot valve is a sort of check valve that is often located at the bottom of a pipeline or at a pump (hence the name). Foot valves function similarly to ball check valves, but they have an open end with a shield or screen covering it to prevent debris from entering the line.
Foot valves keep the suction line between the tank and the pump set primed by preventing oil from returning to the main tank. Foot valves offer a better level of safety than check valves, which may be situated closer to the pump set.
