Value Collection G300 15 Malleable Iron End Cap 1/2 in

Product Description

The VALUE COLLECTION G300 15 is a malleable iron threaded pipe end cap sized for 1/2 inch fittings. It is used to seal the terminal end of a threaded pipe run, stopping flow and capping off unused branch lines in liquid, gas, or steam systems. Rated at 300 psi for liquid and gas service and 150 psi for steam, this Class 150 fitting carries a galvanized finish to resist corrosion. It is manufactured to ANSI/ASME B1.20.1 thread standards. Plumbers, pipefitters, and mechanical contractors install this fitting in commercial and residential piping systems where a clean, pressure-rated pipe termination is required.

This end cap is suited for use on 1/2 inch threaded pipe in water supply, gas distribution, compressed air, and low-pressure steam applications. Its malleable iron construction handles the mechanical stress of threaded assembly without cracking. The galvanized coating makes it appropriate for exposed or mildly corrosive environments. It is a common component in HVAC hydronic systems, plumbing rough-in work, and industrial pipe distribution where branch lines must be capped and pressure-tested before final commissioning.

Key Features

• 300 psi liquid and gas pressure rating for reliable service in pressurized systems
• 150 psi steam pressure rating, suitable for low-pressure steam piping
• Threaded end connection conforms to ANSI/ASME B1.20.1 NPT thread standard
• Malleable iron construction resists cracking and deformation under torque
• Galvanized finish provides corrosion resistance in exposed installations
• Class 150 fitting for use in standard commercial and residential piping

Compatibility

Designed as an OEM-style threaded end cap for 1/2 inch NPT pipe systems in liquid, gas, and steam service meeting Class 150 pressure requirements.

Installation Notes

This fitting is installed by a licensed plumber or pipefitter using a pipe wrench and appropriate thread sealant or PTFE tape applied to the male threads before assembly. Shut off and depressurize the pipe system completely before removing or installing any threaded fittings. Do not overtighten malleable iron fittings, as excessive torque can crack the casting. All gas piping installations must comply with applicable local codes and the International Fuel Gas Code (IFGC).
