Selection notes
Compression inlet sizes refer to the tube's outside diameter, not pipe-thread size. Match the tube OD, tank thread, valve insertion clearance, and unloader-line arrangement to the existing installation. Confirm the 1/8-inch side-port connection before ordering. Replacement references identify the connection configuration; confirm dimensions and clearance against the original valve before installation. Isolate power and fully depressurize the receiver before servicing.
