Double-Male Threaded Irrigation Nipple

A double-male threaded irrigation nipple joins two matching female-threaded components in a straight run. Both ends carry male threads, with central hexagonal faces that provide a place to hold the fitting during assembly.

Check the thread at both ends

The side view illustrates the three-quarter-inch connection form, showing the bore, two threaded ends and central hexagonal collars. Choose the size required by your two mating ports; this photograph does not show every size option.

Choose the matching size

• G1/2 inch and G3/4 inch.
• G1 inch and G1 1/4 inch.
• G1 1/2 inch and G2 inch.

The selected size applies to the two male ends. This fitting connects matching ports rather than reducing between two different thread sizes. Confirm the thread designation as well as nominal diameter before fitting it to a valve, adapter or other irrigation component.

Assemble without loading the joint

Work with the supply off and depressurized. Clean the mating threads, inspect them for damage and use the sealing method appropriate to the confirmed thread connection. Start each joint squarely; do not force a crossed or mismatched thread. Support the connected components so their weight does not bear on the nipple.

Restore water gradually and inspect both joints. If a connection leaks, turn the supply off before correcting it. Compare irrigation fittings when choosing adapters for the rest of your assembly.
