Asc Engineered Solutions 313822009 Ground Joint Union 1/8 in

Product Description

The ASC ENGINEERED SOLUTIONS 313822009 is a 1/8 inch galvanized malleable iron ground joint union rated for 150 PSI service. Ground joint unions use a precision-machined metal-to-metal seat at the center connection, creating a tight seal without a gasket. This fitting is used in threaded pipe assemblies where sections of pipe must be disconnected and reconnected during maintenance or system service. Licensed plumbers and pipefitters install this fitting in low-pressure gas, water, and general service piping systems. At 0.15 pounds, it is a compact, lightweight fitting suited for tight spaces and small-diameter pipe runs.

This union is designed for 1/8 inch threaded pipe and is well suited to residential and light commercial plumbing and mechanical applications. The galvanized coating provides corrosion resistance for use in exposed or moderately damp environments. Ground joint unions are a standard choice wherever a piping system requires a break point for future serviceability, including connections to equipment, valves, and instrumentation on small-bore lines.

Key Features

• Ground joint metal-to-metal seat eliminates the need for a separate gasket
• Galvanized coating for corrosion resistance in exposed service environments
• Malleable iron construction provides strength and ductility in threaded fittings
• 1/8 inch fitting size for small-bore pipe applications
• 150 PSI pressure rating suitable for low-pressure piping systems
• Domestically produced fitting

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/8 inch threaded pipe systems using standard NPT connections in 150-class malleable iron piping assemblies.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Plumbing Code or International Fuel Gas Code where relevant. Shut off and depressurize the piping system completely before disassembling or installing any union fitting. Apply appropriate thread sealant to the male NPT threads before assembly, and tighten the union nut by hand before using a wrench to avoid cross-threading. Do not over-tighten the union nut, as this can damage the ground joint seat and compromise the seal.
