Asc Engineered Solutions 1.NU Pipe Union 1 Inch 150 Lb Galvanized

Product Description

The ASC Engineered Solutions 1.NU is a 1-inch galvanized malleable iron pipe union with a brass-to-iron seat design rated for 150 lb service. It is used to join threaded pipe sections in a way that allows future disconnection without cutting or threading new pipe. The union consists of a male end, a female end, and a ground joint nut that draws the two halves together at the brass-to-iron seating surface, creating a leak-resistant mechanical seal. Licensed plumbers and pipefitters install this fitting in water, gas, and low-pressure steam distribution systems where maintenance access and component removal are routine requirements.

This union is suited for residential and light commercial plumbing and mechanical piping systems. The galvanized finish provides corrosion resistance in exposed or mildly corrosive environments. The brass-to-iron seat is a time-tested configuration that resists galling during assembly and repeated makeup cycles. It is a domestically produced fitting, which may be relevant where project specifications require domestic manufactured goods under Buy American or similar procurement requirements.

Key Features

• 1-inch nominal pipe size fits standard NPT threaded pipe
• Brass-to-iron ground joint seat for leak-resistant, repeatable sealing
• 150 lb pressure rating for water, gas, and low-pressure steam service
• Galvanized malleable iron construction for corrosion resistance
• Domestically produced fitting

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch NPT threaded pipe systems in residential and commercial plumbing and mechanical applications.

Installation Notes

Installation is performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC requirements for the intended service. Shut off and depressurize the pipe system and drain standing liquid before removing or installing any union fitting. Apply an appropriate thread sealant or PTFE tape to the male NPT threads before makeup. Do not overtighten the ground joint nut, as this can damage the brass seating surface and cause leaks.
