Asc Engineered Solutions 8700163408 Galvanized Union 1/2 in

Product Description

The ASC Engineered Solutions 8700163408 is a Class 150 malleable iron galvanized union with 1/2 inch female pipe thread (FPT) connections on both ends. It is used to join two sections of threaded pipe while allowing the joint to be broken and reassembled without disturbing the rest of the piping run. Constructed from malleable iron with a hot-dip galvanized finish, this union resists corrosion in wet and exposed environments. It conforms to Federal Spec WW-U-531C and ANSI B-16.39 for malleable iron unions, and to ANSI B-16.14 for dimensions and ANSI B-2.1 for pipe threads. Licensed plumbers and pipefitters install this fitting in gas, water, and mechanical piping systems.

This union is suited for residential and light commercial plumbing, HVAC hydronic piping, and gas distribution systems where a threaded union connection is required. The 1/2 inch FPT size is common at equipment connections, shutoff valve runs, and branch take-offs. It is sold individually and is appropriate anywhere a serviceable break point is needed in a threaded iron pipe assembly.

Key Features

• Class 150 pressure rating per ANSI B-16.39 for malleable iron unions
• Malleable iron construction with galvanized finish for corrosion resistance
• 1/2 inch FPT connections on both ends for standard threaded pipe assembly
• Tapered pipe threads per ANSI B-2.1 for a leak-resistant seal with thread compound or tape
• Dimensional compliance with ANSI B-16.14 and Federal Spec WW-U-531C
• Sold as individual unit, minimum order quantity of one

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2 inch threaded iron pipe systems, compatible with standard NPT threaded pipe and fittings meeting ANSI B-2.1 thread specifications.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off and depressurize the piping system before disassembling or installing any union. Apply an approved pipe thread sealant compound or PTFE tape to all male threads before assembly. Tighten the union nut by hand first, then with a pipe wrench to achieve a secure, leak-free joint. Follow applicable local plumbing codes and the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC) as required by the application.
