Loc-Line 3/4 inch Ball Socket x NPT Connector

The Loc-Line 3/4-inch Ball Socket x NPT Connector provides the transition between a threaded plumbing connection and the 3/4-inch Loc-Line modular hose system. It is useful when building an adjustable aquarium return outlet.

Confirm both the NPT connection and the Loc-Line system size before assembly. Nominal pipe sizes and the measured outside diameter are different, and similar-looking modular fittings are not automatically interchangeable.

Use a sealant suitable for the mating threaded materials and avoid forcing the connection. Support the attached plumbing, inspect for leaks, and leave enough space to reposition the return outlet during maintenance.
