Penn Machine 2501301001 Pipe Cap 1-1/4 in Socket Weld 3000 Lb

Product Description

The PENN MACHINE 2501301001 is a forged carbon steel pipe cap designed for socket weld connections in high-pressure piping systems. Rated at 3000 lb pressure class and conforming to Schedule 80/XH wall thickness standards, this cap provides a reliable, pressure-tight termination on 1-1/4 inch nominal pipe ends. Manufactured by Pennsylvania Machine Works using a forged construction method, it delivers the structural integrity required in demanding industrial, mechanical, and process piping applications. Certifications include ASME, ASTM A105, and PED, with Canadian registration in all provinces. At 1.01 pounds, it is a compact fitting suited for tight installations.

This pipe cap is used to close off the end of a 1-1/4 inch nominal pipe run in socket weld piping systems. Its forged carbon steel construction makes it appropriate for high-pressure steam, hydronic, gas, and process fluid applications in commercial and industrial settings. The socket weld end style requires the pipe to be inserted into the fitting socket before welding, making it common in systems where threaded connections are not permitted or where a permanent, leak-free seal is required. Licensed pipefitters and mechanical contractors are the primary installers of this fitting.

Key Features

• Forged carbon steel construction for high-pressure integrity
• 3000 lb pressure class rating suitable for demanding service conditions
• Socket weld end style for permanent, weld-seal termination
• Schedule 80/XH rating for compatibility with heavy-wall pipe
• Meets ASME, ASTM A105, and PED certification requirements
• Canadian Registered in all provinces for broad project compliance

Compatibility

Designed as an OEM-style socket weld pipe cap for 1-1/4 inch nominal Schedule 80/XH carbon steel piping systems rated at 3000 lb pressure class, conforming to ASME and ASTM A105 standards.

Installation Notes

Installation of socket weld fittings must be performed by a qualified, licensed pipefitter or welder in accordance with applicable ASME B31 piping codes. Before installation, de-energize, depressurize, and drain the piping system completely. The pipe end should be clean, square-cut, and free of burrs before insertion into the socket. Do not apply heat or begin welding until all flammable materials and pressure sources are clear of the work area.
