Asc Engineered Solutions 1.BU Pipe Union 1 Inch 150 Lb

Product Description

The ASC Engineered Solutions 1.BU is a 1-inch pipe union with a brass-to-iron seat design, rated for 150 lb service. Built from malleable iron with a black finish, this union allows piping sections to be connected or disconnected without rotating the pipe itself. The brass seat provides a reliable metal-to-metal seal that resists corrosion and wear at the mating surfaces. Licensed plumbers and pipefitters install this type of union in gas, steam, and water distribution systems where future serviceability is required. Domestic manufacture supports traceability and consistent material standards.

This union is suited for residential and light commercial plumbing and HVAC hydronic piping applications. It is commonly installed in 1-inch threaded iron pipe systems where the line may need to be broken for equipment service, valve replacement, or system modification. The malleable iron body handles the mechanical stresses of pressurized piping, while the black finish is standard for gas and steam lines. Typical installation points include near water heaters, boilers, unit heaters, and similar serviceable equipment connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Plumbing Code or International Fuel Gas Code as required by service type. Shut off and depressurize the line and allow it to cool fully before removing or installing any union. Apply appropriate thread sealant rated for the service medium to all male threads before assembly. Do not over-tighten the union nut, as this can damage the brass seat and compromise the seal.
