Pipe threads for landscape lighting are NPS as compared to NPT threads for pressurized applications.

What is the difference between n.p.s. threads and n.p.t. ? Are there adapters to change from 1/2 inch male nps to 1/2 inch female npt. Help !!!! I''m trying to retrofit fixtures for a driveway project. Thanks in advance.

NPS threads are straight pipe threads that when assembled with other NPS threaded components will provide free and loose mechanical joints without pressure tightness. NPT threads are tapered pipe threads that when assembles with other NPT components and a sealer will produce a pressure tight joint.

Most of the LANDSCAPE LIGHTING FIXTURES we sell have NPS threads. You can use a standard pipe thread compound on NPS threads to prevent water from getting into the fixtures or junction boxes.
