B38;K Llc 423-001 Poly Sch 40 Close Nipple 1/2 Inch

Product Description

The B38;K LLC 423-001 is a 1/2 inch Schedule 40 close nipple made from polyethylene, designed for use in low-pressure piping systems where a minimal-length threaded connection is required. A close nipple has threads running nearly the full length of the fitting, leaving no unthreaded center section. This makes it useful when two threaded fittings need to be joined with as little spacing as possible. The part weighs approximately 0.05 pounds and measures 1 inch in length. It is sized for standard 1/2 inch pipe thread connections and is suited for plumbing, pumping, and fluid transfer applications.

This close nipple is typically installed in residential and light commercial plumbing systems, pump assemblies, and fluid distribution lines where a compact threaded connection is needed. The Schedule 40 wall rating makes it appropriate for standard working pressures found in common water service and fluid transfer piping. Plumbers, pump technicians, and irrigation installers commonly use close nipples like this one to connect valves, unions, or fittings back-to-back without gap. The 1/2 inch size is one of the most frequently used pipe sizes across residential and light commercial installations.

Installation Notes

This fitting is installed by licensed plumbers or qualified pipe fitters following applicable IPC or local plumbing code requirements. Shut off water supply and relieve system pressure before removing or installing any threaded fittings. Use appropriate thread sealant or PTFE tape on NPT threads before assembly. Do not overtighten threaded plastic fittings, as this can cause cracking at the thread root.
