Spears 54211159590 Pvc Insert Adapter 3/4 in Insert X Fnpt

Product Description

The SPEARS 54211159590 is a standard PVC insert adapter fitting designed to transition between insert and female NPT threaded connections in polyethylene piping systems. Rated for use with ASTM D 2104 Schedule 40/STD and ASTM D 2239 SIDR pressure-rated polyethylene pipe, this fitting measures 2-7/16 inches in length at a 3/4 inch nominal size. The rigid PVC barbed insert construction provides a strong mechanical grip on polyethylene tubing, while the molded gray PVC body resists corrosion and a broad range of chemicals. Licensed plumbers and irrigation technicians are the typical installers of this fitting in both residential and light commercial applications.

This adapter is suited for plumbing, irrigation, and fluid-handling systems where a polyethylene supply line connects to a female NPT threaded port. Common install scenarios include connecting PE water service lines to threaded valves, manifolds, or equipment inlets. The domestic, molded PVC construction meets NSF standards, making it appropriate for potable water applications as well as non-potable irrigation and industrial systems. At 0.05 pounds, the fitting is compact and lightweight, making it straightforward to incorporate into tight installation spaces.
