The NDL INDUSTRIES np-435-007 is a PVC pipe adapter fitting designed to connect two female-threaded pipe ends in a single inline joint. Built entirely from PVC, this adapter handles standard plumbing and irrigation applications where a female-to-female threaded transition is required. The fitting accepts 3/4-inch connections on both ends and is suited for cold- and ambient-temperature water service lines. Plumbers, irrigation contractors, and pool and spa technicians commonly install this type of adapter when joining threaded plastic pipe sections or transitioning between component ports.
This adapter is used in residential and light commercial plumbing systems, irrigation distribution lines, and pool or spa equipment plumbing where 3/4-inch female-threaded connections are present on both mating components. It is a practical solution for connecting two male-threaded fittings, valves, or equipment ports through a single coupling point without the need for additional union hardware.
Designed as an OEM-style replacement or standard-fit adapter for 3/4-inch female-threaded PVC plumbing systems in residential and light commercial applications.
Installation is performed by licensed plumbers or qualified irrigation and pool technicians. Shut off the water supply and relieve system pressure before threading any fittings. Apply thread sealant tape or liquid thread compound to mating male threads per local plumbing code requirements before hand-tightening and final wrench-seating. Do not overtighten PVC threaded fittings, as excess torque can crack the fitting body.
