Blue-Nut Compression Female-Thread 90-Degree Elbow

Blue-Nut Compression Female-Thread 90-Degree Elbow

This compression elbow combines a quarter-turn change of direction with a female threaded connection. The blue nut accepts the pipe on one side, and the black body turns the water path through 90 degrees toward the threaded end. This geometry helps position a pipe connection beside a valve, around a corner or beneath a compatible irrigation component without asking the pipe itself to make a tight bend. Allow room around the nut so the connection remains accessible after installation.

Choose both connection sizes

Read each option as two connection measurements: the metric value identifies the pipe outside diameter, and the inch value identifies the nominal threaded connection. A matching pipe size alone does not establish thread compatibility. The female thread receives a matching male-threaded component inside its socket. Check that the mating thread can engage freely without bottoming out or forcing the plastic body. Confirm the thread standard with the mating equipment as well as its nominal size. Keep enough space for the connected equipment and for access during maintenance.

Prepare a supported connection

Cut the pipe square and clean away burrs or loose material before assembly. Check that the pipe end is round and undamaged. Use a compatible pipe insert where the pipe system requires one, and follow the fitting assembly instructions for engagement and tightening. Support nearby pipework and equipment so their weight does not pull on the connection. Select a thread sealing method appropriate to both mating parts, and avoid excessive force.

Check before regular irrigation

Pressurize the assembled line gradually and inspect both the compression and threaded connections for leakage. Recheck the installation after repositioning equipment or servicing a valve. Match operating pressure and temperature to the verified limits of every component in the line. Leave the fitting accessible so that future inspection and replacement can be carried out without straining the pipe.
