Speck 40mm Union

The Speck 40mm pool pump union fits on the return end of a Speck swimming pool pump.
A Speck 40mm Pump Union is a type of mechanical fitting used to connect a pump to a pipe or hose. It typically consists of a threaded male and female end that can be tightened together using a nut and bolt. The union allows for the easy removal and replacement of the pump, as it can be disconnected from the piping system without the need to disassemble the entire system. The 40mm size refers to the diameter of the connection, which is typically measured in millimetres.
