Value Collection 420S04 1/2 Inch Steel Pipe Coupling

Product Description

The VALUE COLLECTION 420S04 is a Class 150 galvanized steel pipe coupling designed for threaded NPS connections in plumbing, gas distribution, and industrial piping systems. This fitting joins two pipe sections of equal diameter and is rated for liquid and gas service at 300 psi and steam service at 150 psi. The galvanized finish provides corrosion resistance in wet or exposed environments. The coupling meets ASTM standards and uses National Pipe Straight threading, making it a straightforward replacement or new-install component for licensed plumbers and pipefitters working on both residential and light commercial systems.

This coupling is suited for use in water supply lines, compressed air distribution, natural gas and propane piping, and low-pressure steam systems. At 1/2 inch fitting size, it is commonly installed in branch lines and secondary runs where standard Class 150 threaded steel fittings are specified. It is appropriate for applications where a galvanized finish is required to meet corrosion resistance specifications or local code requirements.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC) where relevant. Shut off and depressurize the line completely before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to male threads before assembly. Do not over-tighten threaded connections, as this can damage threads or crack fittings.
