Asc Engineered Solutions 1D.NU 1-1/2 in Pipe Union 150 Lb Galvanized

Product Description

The ASC ENGINEERED SOLUTIONS 1D.NU is a 1-1/2 inch galvanized pipe union rated at 150 lb, constructed from brass and malleable iron with a brass-to-iron seat configuration. This union provides a reliable, removable threaded connection in piping systems where future disassembly is required without cutting pipe. The galvanized finish adds corrosion resistance for use in wet or exposed service environments. Plumbers and pipefitters install this fitting in domestic water, industrial, and general-purpose piping systems where a code-compliant, pressure-rated union connection is needed.

This union is suited for residential and light commercial plumbing installations where 1-1/2 inch threaded pipe connections are standard. The brass seat mating against the iron body seat creates a metal-to-metal seal that holds up under repeated assembly and disassembly cycles. It is commonly installed on water heater connections, boiler piping, and service valve bypass assemblies where the line may need to be broken for maintenance or equipment replacement.

Key Features

• 1-1/2 inch nominal pipe size for standard threaded connections
• 150 lb pressure rating suitable for general-purpose plumbing service
• Brass x iron seat design provides durable metal-to-metal sealing
• Galvanized finish for corrosion resistance in wet or outdoor environments
• Malleable iron body construction for strength and impact resistance
• Domestically manufactured fitting

Compatibility

Designed as an OEM-style replacement or new-installation union for 1-1/2 inch threaded malleable iron piping systems rated at 150 lb working pressure.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the piping system completely before removing or installing any union fitting. Apply listed thread sealant or PTFE tape to the male threads per local code requirements. Do not over-tighten the union nut, as this can damage the seat faces and compromise the seal.
