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

Product Description

The ASC Engineered Solutions B.NU is a 1/4-inch pipe union designed with a brass-to-iron seat interface and rated at 150 lb working pressure. Constructed from brass and malleable iron with a galvanized finish, this domestically produced union allows a piping section to be disconnected without rotating adjacent pipe. It is suited for low-pressure gas, water, and steam distribution lines where a serviceable mechanical joint is required. Licensed plumbers and pipefitters install this fitting in new construction and retrofit applications where future serviceability of the line is a priority.

This union is intended for residential and light commercial plumbing and mechanical piping systems operating at or below 150 lb rated pressure. The 1/4-inch size fits branch lines, instrument connections, and low-flow service runs. The galvanized malleable iron body resists corrosion in exposed or semi-exposed installations, while the brass seat provides a reliable metal-to-metal sealing surface that holds up through repeated assembly and disassembly cycles.

Key Features

• 150 lb pressure rating suitable for low-pressure water, gas, and steam service
• Brass-to-iron seat design provides durable, leak-resistant metal-to-metal seal
• Galvanized finish on malleable iron body for corrosion resistance in exposed applications
• 1/4-inch size for branch lines and instrument tap connections
• Domestically produced malleable iron construction
• Allows pipe disconnection without rotating adjacent pipe sections

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/4-inch threaded piping systems rated at 150 lb, including water, low-pressure steam, and gas distribution lines conforming to standard NPT thread specifications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with the International Plumbing Code or International Fuel Gas Code as applicable. Isolate and depressurize the piping system completely before disassembling or installing this union. Apply a suitable thread sealant or PTFE tape to all male NPT threads per manufacturer recommendations and local code requirements. Do not over-tighten the union nut, as excess torque can distort the seat and compromise the seal.
