PA Series Adapter

Features

Made of stainless steel 316L material

Maximum operating temperature of pipe fittings is 1000℉( 537℃ )

Processed in multi spindle CNC machine to ensure accuracy in all direction

Smooth and flat threaded surface for better conducive seal and higher wear-resistant

Each fitting is marked with the thread type, for ease-of-use and avoid misconnection
