    Quick Selection Guide

    Select the stub end type (Type A/B/C) according to the matching flange.

    The material of the stub end must be the same as or compatible with the base material of the pipe to which it is connected.

    Select the appropriate pressure rating for the stub end based on the design pressure and temperature.

    The stub end length should be selected based on the specific design of the piping system.
