Asc Engineered Solutions 812509412 Malleable Iron Union 2.5 in

Product Description

The ASC Engineered Solutions 812509412 is a black malleable iron union designed for joining and disassembling threaded pipe runs in plumbing, mechanical, and industrial piping systems. At 2.5 inches, this union provides a reliable, reusable threaded connection point that allows sections of pipe to be removed or replaced without cutting. The black coating provides corrosion resistance suited for gas distribution, compressed air, and similar dry or low-moisture service. Licensed plumbers and pipefitters are the primary installers for this fitting type.

This union is used in residential and commercial piping applications where a breakable threaded connection is required. Common installations include gas supply lines, steam systems, compressed air distribution, and general-purpose black iron pipe assemblies. The 2.5-inch size is standard for mid-to-large diameter runs found in commercial mechanical rooms, industrial process lines, and HVAC gas train assemblies.

Key Features

• Black coating for corrosion resistance in gas and dry mechanical service
• Malleable iron construction provides strength and impact resistance over cast iron
• 2.5-inch fitting size suits mid-to-large diameter threaded pipe systems
• Threaded union design allows pipe disassembly without cutting
• Import construction rated for standard threaded iron pipe applications

Compatibility

Designed as an OEM-style replacement fitting for standard 2.5-inch threaded black iron pipe systems using NPT thread connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable local mechanical and plumbing codes. Shut off and depressurize the pipe system completely before removing or installing any union. Apply an appropriate thread sealant or PTFE tape to all male threads before assembly. Do not over-tighten the union nut, as this can distort the sealing seat and cause leaks.
