Bmi Usa 35501 Malleable Iron Pipe Cap 1/8 Inch Black

Product Description

The BMI USA 35501 is a 1/8 inch malleable iron pipe cap finished in black, used to close off the end of a threaded pipe run. This fitting creates a secure, pressure-holding termination on an open pipe end, preventing flow, contamination, or accidental contact with the pipe opening. Malleable iron construction gives this cap the durability to hold up in piping systems carrying gas, steam, or liquid under pressure. It is a standard threaded fitting installed by licensed plumbers, pipefitters, and HVAC technicians during system assembly, maintenance, or temporary service isolation.

This cap is suited for residential and light commercial piping applications where a small-diameter threaded termination is needed. Common install scenarios include gas supply lines, water distribution systems, and steam piping where a 1/8 inch NPT end must be capped off cleanly. Its compact size makes it practical in tight spaces and manifold configurations where multiple fittings are in close proximity.

Key Features

• Malleable iron construction for strength and resistance to mechanical stress
• Black finish suitable for gas and steam piping applications
• 1/8 inch threaded connection for standard NPT pipe runs
• Lightweight at 0.03 pounds for easy handling and installation

Compatibility

Designed as a standard threaded pipe cap for 1/8 inch NPT piping systems in plumbing, gas, and HVAC applications.

Installation Notes

Installation is performed by a licensed plumber, pipefitter, or HVAC technician. Shut off all pressure to the line and depressurize the system before threading on this cap. Apply appropriate thread sealant or PTFE tape to the male threads before installation to ensure a leak-free seal. Verify the final connection with a pressure test before returning the system to service.
