Asc Engineered Solutions 318901428 Iron Pipe Cap 3 Inch Xh

Product Description

The ASC ENGINEERED SOLUTIONS 318901428 is a 3-inch extra-heavy (XH) black malleable iron pipe cap with female pipe thread (FPT) connection. It is designed to close the end of a threaded pipe in plumbing, gas distribution, and mechanical piping systems. Manufactured to ASTM A-197 malleable iron standards and dimensioned to ASME B16.3, this cap meets the pressure and strength requirements expected in demanding service environments. Weighing 4.71 pounds, it is suited for installations where a robust, code-compliant pipe termination is required. Licensed plumbers and pipefitters install this fitting in both new construction and retrofit applications.

This cap is used in residential and commercial plumbing and gas piping systems where a threaded pipe end must be permanently or temporarily sealed. The extra-heavy (XH) rating makes it appropriate for higher-pressure service runs. The black finish is standard for gas and mechanical piping applications. It installs on any standard NPT-threaded pipe end conforming to ASME B1.20.1 thread specifications, making it broadly compatible across common piping configurations in the plumbing and mechanical trades.

Key Features

• Extra-heavy (XH) strength rating for higher-pressure service applications
• Malleable iron construction per ASTM A-197 for durability and impact resistance
• Dimensioned and pressure rated to ASME B16.3 standard
• Female pipe thread (FPT) connection per ASME B1.20.1 for standard NPT compatibility
• Black finish standard for gas and mechanical piping systems
• UL and FM listed (UL FM: Yes) for use in approved fire protection and gas piping installations

Compatibility

Designed as an OEM-style replacement or new-installation cap for 3-inch NPT-threaded pipe ends in plumbing, gas, and mechanical piping systems conforming to ASME B16.3 and ASME B1.20.1 standards.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Plumbing Code (IPC), and the International Fuel Gas Code (IFGC) where applicable. Shut off all system pressure and purge any gas or fluid from the line before fitting installation. Apply thread sealant or PTFE tape appropriate for the service medium to the male threads before engaging the cap. Do not use pipe wrenches on the cap body in a way that could crack or deform the fitting.
