Asc Engineered Solutions E.BU Pipe Union 3/4 Inch 150 Lb

Product Description

The ASC Engineered Solutions E.BU is a 3/4 inch malleable iron pipe union with a brass-to-iron seat design, rated for 150 lb service. This union provides a reliable threaded connection point in gas, steam, or water piping systems, allowing sections of pipe to be assembled or disconnected without disturbing the rest of the run. The black finish is standard for malleable iron pipe fittings used in gas and steam applications. Licensed plumbers, pipefitters, and HVAC mechanics install this fitting in commercial and residential mechanical systems where a serviceable union joint is required by code or good practice.

This union is suited for 3/4 inch threaded pipe installations in residential and light commercial applications including gas distribution, low-pressure steam, and hydronic heating systems. The brass seat on the iron union nut provides a metal-to-metal seal that resists corrosion at the seating surface and holds integrity under thermal cycling. Its 150 lb pressure rating makes it appropriate for standard working pressures found in most building mechanical systems.

Key Features

• 3/4 inch pipe size fits standard NPT threaded pipe and fittings
• 150 lb pressure rating suitable for gas, steam, and water service
• Brass seat against iron seat design provides a durable, corrosion-resistant sealing surface

Compatibility

Designed as an OEM-style replacement or new-installation union for 3/4 inch NPT threaded pipe systems, compatible with standard malleable iron and black iron pipe fittings in 150 lb service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IFGC, or IPC requirements. Shut off and depressurize the pipe system completely before disassembling or installing any union. Apply thread sealant or tape rated for the intended service medium to all male NPT threads before assembly. Hand-tighten the union nut before final tightening with a pipe wrench to avoid cross-threading the seat.
