Asc Engineered Solutions 8700163309 Galvanized Union

Product Description

The ASC ENGINEERED SOLUTIONS 8700163309 is a 1/4-inch FPT malleable iron galvanized union rated for Class 150 service. This union fitting connects two sections of threaded pipe while allowing disconnection without disturbing the rest of the piping run. The galvanized finish provides corrosion resistance in exposed or moderately humid environments. It is manufactured to ANSI B-16.39 for malleable iron unions, ANSI B-16.14 for dimensions, and ANSI B-2.1 for pipe threads, making it a code-compliant choice for plumbing and mechanical piping systems. Licensed plumbers and pipefitters are the primary installers of this fitting.

This fitting is suited for residential and light commercial plumbing, gas distribution, and mechanical piping applications where a threaded union connection is required at 1/4-inch pipe size. The malleable iron construction handles vibration and moderate mechanical stress better than cast iron, making it appropriate for systems subject to thermal cycling or minor pipe movement. It is sold individually and is commonly used in repair and maintenance work where section isolation is needed.

Key Features

• 1/4-inch FPT connections on both ends for standard threaded pipe
• Malleable iron construction resists vibration and mechanical stress
• Galvanized finish for corrosion resistance in exposed applications
• Class 150 pressure rating per ANSI B-16.39
• Meets Federal Specification WW-U-531C for malleable iron unions
• Compliant with ANSI B-16.14 dimensional standards and ANSI B-2.1 pipe thread standards

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/4-inch NPT threaded piping systems in plumbing and mechanical applications requiring a Class 150 malleable iron union.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IFGC requirements where gas service is involved. Shut off and depressurize the affected piping system completely before disassembling or installing any union fitting. Apply appropriate thread sealant or PTFE tape to male threads before assembly and tighten to hand-tight plus wrench-tight without over-torquing malleable iron threads. Inspect the union seat and nut for debris before final makeup to ensure a leak-free joint.
