Mueller Streamline PIPE1X120 Black Iron Pipe 1x120

Product Description

The MUELLER STREAMLINE PIPE1X120 is a threaded black iron pipe measuring 1 inch in diameter and 120 inches in length. It is built for natural gas and propane distribution in HVAC and mechanical piping systems. The pipe delivers a full 10-foot uninterrupted run, reducing the total number of joints required in a gas distribution layout. Fewer joints mean fewer potential leak points and a cleaner installation. Licensed HVAC technicians, pipefitters, and plumbers install this type of pipe during new construction, equipment replacement, and gas line extension work.

This pipe is suited for residential and light commercial applications where the system requires higher flow capacity or longer main runs. Typical installations include mechanical rooms serving boilers, rooftop units, and larger HVAC equipment. The 1-inch diameter accommodates higher gas volume demands compared to smaller distribution branches, making it appropriate for main trunk runs feeding multiple appliances or a single high-input unit.

Key Features

• 1-inch nominal diameter supports higher gas flow capacity for main distribution runs
• 120-inch length reduces joint count and simplifies system layout
• Threaded ends allow direct connection to standard fittings, valves, and couplings
• Black iron construction is the accepted material for gas piping per applicable codes
• Well suited for mechanical room installations feeding boilers and large HVAC equipment

Compatibility

Designed as a standard threaded black iron pipe for use in natural gas and propane distribution systems where 1-inch nominal iron pipe is specified.

Installation Notes

Installation must be performed by a licensed plumber, pipefitter, or HVAC technician in accordance with IFGC and applicable local codes. Shut off the gas supply at the service entry and verify the line is depressurized before cutting into any existing piping. Apply an approved thread sealant or PTFE tape rated for gas service to all threaded connections. Pressure-test the completed assembly per local authority requirements before restoring gas service.
