Value Collection 420S12 Malleable Iron Pipe Coupling 1-1/4 in

Product Description

The VALUE COLLECTION 420S12 is a Class 150 malleable iron pipe coupling designed for threaded NPS pipe connections in plumbing, HVAC hydronic, and industrial piping systems. It carries a 300 psi pressure rating for liquid and gas service and a 150 psi rating for steam applications. The galvanized finish provides corrosion resistance in wet or humid environments. At 0.52 pounds, it is a lightweight, durable fitting suited for standard trade installations where a reliable, code-compliant coupling is required. Licensed plumbers and pipefitters are the typical installers for this type of fitting.

This coupling is used in residential and commercial piping systems where 1-1/4 inch NPS threaded connections are required. It is appropriate for liquid, gas, and low-pressure steam service. Common applications include supply and return lines in hydronic heating systems, compressed air distribution, gas distribution piping, and general-purpose plumbing. The galvanized coating makes it suitable for exposed or semi-exposed installations where moisture is a factor.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements. Depressurize and isolate the pipe section before beginning work. Apply an approved thread sealant or PTFE tape to all male threads before assembly. Hand-tighten first, then use a pipe wrench to achieve a proper mechanical connection without over-torquing the fitting.
