John Guest Stem Adaptor 3/8" Stem x 3/8" BSP – PI051213S

The John Guest PI051213S Stem Adaptor provides a quick and reliable way to convert a 3/8" John Guest push-fit connection to a 3/8" BSP threaded connection.

Manufactured from tough grey acetal copolymer, the PI051213S is designed for demanding fluid, air and water treatment applications. John Guest push-fit technology provides an instant, leak-tight connection without the need for specialist tools, hot works or adhesives, while allowing the connection to be disconnected and reconnected quickly when required.
