Anvil 0321201139 Steel Pipe Coupling 1/2 in Threaded 300 Psi

Product Description

The ANVIL 0321201139 is a galvanized steel threaded pipe coupling designed to join two sections of pipe in a straight run. Built to Class 300 standards and compliant with ASTM specifications, it handles liquid, gas, and steam service at up to 300 psi. The 1/2-inch fitting uses NPS threading for a secure, leak-resistant connection. At 0.24 pounds, it is a compact, durable fitting suited for plumbing, HVAC piping, and mechanical systems. Licensed plumbers and pipefitters install this type of coupling in both new construction and retrofit applications where a reliable threaded connection is required.

This coupling is rated for use in liquid, gas, and steam piping systems operating within Class 300 pressure limits. The galvanized finish provides corrosion resistance for installations in exposed or moderately corrosive environments. It is commonly used in commercial and residential piping systems where NPS-threaded fittings are specified, including water supply lines, gas distribution piping, and steam distribution systems.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2-inch NPS threaded steel pipe systems rated to Class 300 service conditions.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC and IFGC code requirements. Shut off and depressurize the piping system fully before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the NPS threads before assembly. Do not overtighten, as this can crack galvanized coatings or damage threads.
