A712 Long Pipe Style Adapter Nipple

The A712 provides a direct change from a 2" grooved connection to a 2" NPT connection in one straight fitting. This allows a mechanically joined grooved piping section to connect with threaded equipment without adding multiple transition components.

The grooved side should be matched with the correct clamp and gasket, while the threaded side should be matched to the intended NPT connection. Verify both mating components before installation so the adapter fits the surrounding piping correctly.

Dixon lists the A712 with a 4" end-to-end dimension, giving the nipple additional straight length between the grooved and threaded ends. This extra reach can help where valves, manifolds, or other equipment need additional spacing from the grooved joint.

Available installation space should be reviewed before assembly because the longer body changes the final position of the connected threaded component. Proper placement helps keep both ends aligned without introducing unnecessary piping stress.

Dixon identifies A712 as the carbon steel 2" version in the AN Series Long Pipe Style Nipple family. The rigid steel body provides a durable transition component for compatible industrial piping systems.

Material suitability should be reviewed against the transferred media, surrounding piping, environmental exposure, and overall system requirements. The fitting should be protected from service conditions that are unsuitable for carbon steel.

The grooved side remains mechanically joined with a compatible clamp and gasket rather than being permanently welded into the system. This can make removal easier when nearby piping or connected equipment requires inspection, maintenance, or replacement.

Inspect the groove profile, clamp, gasket, threads, and final alignment during installation. Full groove engagement and properly matched threads help support a secure transition between the two connection styles.
