Anvil 0321201113 Steel Pipe Coupling 1/4 in Threaded 300 Psi

Product Description

The ANVIL 0321201113 is a galvanized steel pipe coupling designed for joining threaded pipe sections in liquid, gas, and steam service lines. Rated at 300 psi for both liquid and gas service as well as steam service, this Class 300 fitting uses NPS-standard internal threads for reliable, leak-resistant connections. The galvanized finish provides corrosion resistance in damp or moderately corrosive environments. Weighing approximately 0.1 pounds, this compact 1/4 inch coupling is a standard consumable stocked by plumbing and pipefitting contractors for both new construction and repair work. API standards compliance supports use in a range of professional piping applications.

This coupling is suited for residential and light commercial piping systems where 1/4 inch threaded connections are required. Typical applications include gas distribution branch lines, compressed air systems, hydraulic service lines, and low-pressure steam distribution. Plumbers, pipefitters, and mechanical contractors install this fitting where two threaded pipe ends must be joined in a straight run. Its small size makes it common in tight-space installations and instrument piping runs.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable mechanical and plumbing codes such as the IPC or IFGC. Shut off and depressurize the line completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten; bring the fitting to hand-tight and finish with a pipe wrench to achieve a proper seal without stressing the fitting body.
