Midland Industries 62776B1 Barstock Half Coupling 1000 Psi Ss

Product Description

The MIDLAND INDUSTRIES 62776B1 is a barstock half coupling designed for high-pressure piping connections in industrial and commercial systems. It provides a 1-1/4 inch female pipe thread (FPT) connection on one end and a 1-1/4 inch butt weld connection on the other, allowing a threaded pipe to be joined to a welded piping run. Manufactured from 304 stainless steel barstock, it is rated to 1000 psi and conforms to MSS SP-114 dimension standards. At 0.34 pounds, this compact fitting is suited for corrosive-environment piping where stainless steel is required. Licensed plumbers and pipefitters are the typical installers.

This half coupling is used in high-pressure piping systems requiring stainless steel construction, including chemical process lines, food-service piping, marine applications, and industrial fluid handling. The FPT end accepts a standard male-threaded pipe or nipple, while the butt weld end integrates directly into a welded stainless steel piping system. It falls within the 1000 psi and above pressure class for 304 stainless steel fittings, making it appropriate for demanding service conditions where carbon steel fittings are unsuitable.

Key Features

• 1-1/4 inch FPT to 1-1/4 inch butt weld configuration for mixed-connection piping transitions
• 1000 psi pressure rating for high-pressure service
• 304 stainless steel barstock construction for corrosion resistance
• Conforms to MSS SP-114 dimension standards
• Lightweight at 0.34 pounds for easy handling during installation

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/4 inch stainless steel high-pressure piping systems conforming to MSS SP-114 standards.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or ASME B31 piping standards. Depressurize and drain the piping system fully before cutting in or threading any fitting. The butt weld end must be welded by a qualified welder; do not use the fitting in weld-end service without proper fusion. Apply thread sealant rated for the service fluid to the FPT connection before assembly.
