Pipe Fittings

Pipe fittings are typically used to join components together The measurements specified in the Tables below conform to
in a gas handling system – such as attaching a flowmeter to National Pipe Thread (NPT) designations, and may be either
a regulator, or installing a relief valve. They are also used in female (internal) type connections, or male (external) type
systems which have been constructed using rigid pipe, as connections – abbreviated as NPT(F) or NPT(M) accordingly.
opposed to tubing. All pipe fittings shown have a maximum operating pressure
of at least 3000 psig.
