Value Collection 420S10 Steel Pipe Coupling 1 Inch Nps

Product Description

The VALUE COLLECTION 420S10 is a Class 150 galvanized steel pipe coupling designed for threaded NPS pipe connections in liquid, gas, and steam service. This fitting accepts standard National Pipe Straight threads on both ends and is rated for 300 psi on liquid and gas lines and 150 psi on steam lines. It is manufactured to ASTM standards and finished with a galvanized coating to resist corrosion in demanding environments. Plumbers, pipefitters, and mechanical contractors install this type of coupling to join two sections of threaded pipe inline without reducing the bore diameter.

This coupling is suited for residential and commercial piping systems where a reliable inline connection is required on 1-inch NPS-threaded pipe. Typical applications include water supply lines, compressed air distribution, natural gas branch lines, and low-pressure steam systems. The galvanized finish makes it appropriate for exposed or semi-exposed installations where basic corrosion protection is needed. Each unit is sold individually.

Key Features

• 300 psi liquid and gas pressure rating for general service piping
• 150 psi steam pressure rating suitable for low-pressure steam distribution
• Threaded NPS end connections on both ends for standard pipe fitment
• Galvanized steel construction provides corrosion resistance
• Class 150 fitting conforming to ASTM standards
• 1-inch fitting size for common residential and light commercial pipe diameters

Compatibility

Designed as an OEM-style replacement and standard-service fitting for 1-inch NPS threaded steel pipe systems in liquid, gas, and low-pressure steam applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes, including IPC and IFGC requirements where relevant. 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 over-torque threaded connections, as this can crack fittings or damage threads.
