Asc Engineered Solutions 2.BU Pipe Union 2 in 150 Lb

Product Description

The ASC Engineered Solutions 2.BU is a 2-inch threaded pipe union rated for 150 lb service, built with a brass seat mating against an iron seat for a reliable, leak-resistant connection. The body is malleable iron with a black finish, designed for use in gas, air, and water distribution systems where a removable union fitting is required. This union allows technicians to disconnect and reconnect piping runs without cutting pipe, making it a standard component in mechanical room installations and service-accessible line segments. The brass-to-iron seat combination resists galling and provides a durable metal-to-metal seal suitable for repeated make-and-break service.

This fitting is suited for residential and light commercial plumbing, HVAC hydronic systems, gas distribution piping, and compressed air lines where 150 lb malleable iron fittings are specified. It is domestically produced and meets standard NPT threaded pipe fitting requirements. Plumbers, pipefitters, and HVAC technicians install this union wherever code or system design requires a serviceable disconnect point in a threaded iron pipe system.

Key Features

• 2-inch nominal pipe size with standard NPT threads for direct compatibility with Schedule 40 threaded pipe
• Brass seat mating against iron seat provides a durable, gall-resistant metal-to-metal seal
• 150 lb pressure rating suitable for gas, water, and compressed air service
• Malleable iron construction with black finish for corrosion resistance in typical mechanical environments
• Domestically manufactured to standard malleable iron pipe fitting specifications
• Serviceable union design allows line disconnection without pipe cutting or threading

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 2-inch threaded malleable iron pipe systems rated at 150 lb, including gas, water, and compressed air distribution piping in residential and commercial applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IPC, and IFGC requirements for threaded pipe systems. Shut off and depressurize the system and verify zero pressure before disassembling or installing any union fitting. Apply appropriate thread sealant or tape to NPT threads per the service medium — confirm sealant compatibility with gas service before use. Hand-tighten the union nut before applying wrench torque, and do not over-tighten, as malleable iron threads can crack under excessive force.
