The adapter nipple M/F 1/2″ × 3/8″ is a standard hydraulic connector enabling a transition between two different thread sizes in a pipework system. The 1/2″ male thread (G 1/2″) is used for screw connection into a valve body or device, while the 3/8″ female thread (G 3/8″) accepts pipework or accessories of a smaller diameter.
This type of adapter is commonly used when installing pressure gauges, pressure sensors or flow meters into pool pipework systems, where the device manufacturer and the pipe manufacturer use different thread standards. A properly sealed joint with PTFE tape or a moulded seal prevents any leaks under operating pressure.
The nipple is made of corrosion-resistant material suitable for contact with pool water and disinfectants. Its small dimensions and low price make this part an indispensable item in the stock of every pool technician or plumber.
