Asc Engineered Solutions B.BU Pipe Union 1/4 in 150 Lb

Product Description

The ASC Engineered Solutions B.BU is a 1/4 inch malleable iron pipe union with a black finish, rated at 150 lb. It features a brass-to-iron seat design that provides a reliable metal-to-metal seal, reducing the risk of leakage at the joint. This union is used in threaded pipe assemblies to allow sections of pipe to be connected or disconnected without rotating the pipe itself. Plumbers and pipefitters install this fitting in low-pressure gas, water, and steam distribution systems where a serviceable threaded connection is required.

This union is suited for residential and light commercial piping applications. It is domestically produced and fits standard 1/4 inch NPT threaded pipe. The black finish indicates it is intended for gas piping or non-potable water systems rather than potable water or steam where galvanized or brass unions are typically specified. The brass seat on the iron body reduces galling and provides a tighter shutoff than an all-iron seat under normal operating pressures.

Key Features

• 1/4 inch NPT threaded connection for standard pipe sizing
• 150 lb pressure rating suitable for low-pressure gas and water systems
• Brass x iron seat design for improved sealing and reduced galling
• Malleable iron body provides strength and impact resistance over cast iron
• Black finish for gas piping and non-potable applications
• Domestic manufacture

Compatibility

Designed as an OEM-style replacement or direct installation fitting for 1/4 inch NPT threaded malleable iron pipe systems rated at 150 lb, including low-pressure gas, steam, and water distribution assemblies.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable codes such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off all gas or water supply and depressurize the line before disassembling or installing the union. Apply an appropriate thread sealant or pipe thread compound rated for the service fluid to all NPT threads before assembly. Do not over-tighten; hand-tight plus wrench turns appropriate for the fitting material is standard practice.
