The BMI USA 6101 is a 1/8-inch lead-free brass pipe union designed for use in plumbing systems where a removable, pressure-tight connection between two pipe sections is required. Pipe unions allow technicians to disconnect and reconnect pipe runs without cutting, making them a go-to fitting for service and maintenance work. Constructed from lead-free brass, this union meets modern potable-water safety standards and delivers solid corrosion resistance in both hot and cold water lines. At 0.18 pounds, it is a lightweight but durable fitting suited for tight spaces and small-diameter piping runs.
This union is appropriate for residential and light commercial plumbing installations where 1/8-inch pipe connections must be made or broken for routine service. Typical applications include branch connections, equipment isolation points, and any small-bore line where future serviceability is a priority. Licensed plumbers and pipefitters install this fitting in water supply, hydronic, and compatible low-pressure piping systems. Its lead-free brass construction makes it suitable for use in potable water applications where code compliance with lead-free requirements is mandatory.
Designed as an OEM-style replacement or direct-install fitting for 1/8-inch pipe systems in residential and light commercial plumbing applications.
Installation of pipe unions should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure completely before disassembling or installing any union fitting. Use appropriate thread sealant or PTFE tape on male pipe threads as required by the fitting type and system fluid. Do not overtighten the union nut, as brass fittings can be damaged by excessive force.
