Asc Engineered Solutions 1B.BMCAP Pipe Cap 1-1/4 in Fnpt

Product Description

The ASC Engineered Solutions 1B.BMCAP is a 1-1/4 inch female NPT (FNPT) malleable iron pipe cap rated at 150 lb. It is designed to terminate or seal the end of a threaded pipe run in gas, steam, or liquid piping systems. The black finish is standard for low-pressure gas and general-purpose piping applications. Plumbers, pipefitters, and HVAC technicians install this fitting as part of pressure tests, system shutoffs, or permanent line terminations. The malleable iron construction provides reliable thread engagement and impact resistance under normal service conditions.

This pipe cap is used in residential and light commercial piping installations where a threaded termination is required. Common applications include capping unused branch outlets on gas distribution lines, steam systems, and water supply piping. The FNPT thread pattern is compatible with standard NPT-threaded pipe and fittings. The 150 lb pressure class suits low- to medium-pressure service conditions typical in building mechanical systems.

Key Features

• 1-1/4 inch FNPT connection for standard NPT threaded pipe
• 150 lb pressure class rated for low- to medium-pressure service
• Malleable iron construction for thread integrity and impact resistance
• Black finish suitable for gas piping and general mechanical systems
• Domestic manufacture

Compatibility

Designed as an OEM-style replacement or standard stock fitting for 1-1/4 inch NPT threaded pipe systems in residential and light commercial mechanical applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable local codes and IFGC or IPC requirements for the service type. Apply an appropriate thread sealant or PTFE tape to the male threads before engagement. Shut down and depressurize the piping system completely before removing or installing any threaded fittings. Do not overtighten, as excessive torque can crack malleable iron fittings.
