Anvil 0321201105 Steel Pipe Coupling 1/8 in Nps 300 Psi

Product Description

The ANVIL 0321201105 is a galvanized steel pipe coupling designed to join two sections of threaded pipe in fluid and gas distribution systems. Sized at 1/8 inch NPS, this Class 300 fitting handles liquid and gas service at up to 300 psi and steam service at up to 300 psi. The threaded end connections conform to National Pipe Straight (NPS) standards and meet API specifications. Licensed plumbers, pipefitters, and mechanical contractors install this type of coupling in commercial and industrial piping systems where reliable, leak-free joints are required.

This coupling is suited for low-diameter branch lines and service connections in plumbing, HVAC hydronic systems, compressed air lines, and steam distribution piping. The galvanized finish provides corrosion resistance for both indoor and moderate-exposure outdoor installations. Its compact 1/8 inch size makes it a common fit for instrument taps, gauge connections, and small-bore service lines where NPS threaded fittings are specified.

Key Features

• Class 300 rating supports 300 psi liquid, gas, and steam service
• 1/8 inch NPS threaded end connections for standard pipe engagement
• Galvanized finish for corrosion resistance
• Steel construction for durability under pressure and temperature cycling
• Meets API standards for industrial piping applications

Compatibility

Designed as an OEM-style threaded pipe coupling for 1/8 inch NPS piping systems rated for Class 300 liquid, gas, and steam service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes. Depressurize and isolate the piping system fully before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to male threads before assembly; do not overtighten, as this can crack fittings or distort threads. Verify pressure rating compatibility with the system before returning to service.
