Smith-blair BAKCOUP114 Standard Pipe Coupling 1-1/4 in

Product Description

The SMITH-BLAIR BAKCOUP114 is a standard pipe coupling designed for use on 1-1/4 inch steel pipe. Couplings of this type create a pressure-rated mechanical joint between two pipe ends, restoring continuity to a piping system without the need for welding or threading at the joint. This fitting is suited for repair and installation work on steel pipe runs in water, wastewater, and general industrial fluid systems. Licensed plumbers and pipefitters are the typical installers, and the coupling is appropriate for both new construction and field repair applications.

This coupling is intended for standard-service steel pipe at the 1-1/4 inch nominal pipe size. It is well suited to municipal water distribution, commercial plumbing, and industrial process piping where a reliable mechanical coupling is preferred over a welded or threaded connection. The design accommodates standard pipe outside diameters for 1-1/4 inch steel pipe, making it a practical field-repair and permanent-installation option across a range of system pressures and layouts.

Key Features

• Standard mechanical coupling configuration for 1-1/4 inch steel pipe
• Eliminates the need for welding or threading at the coupling joint
• Suitable for water, wastewater, and general-service fluid piping systems
• Field-repair and permanent-installation compatible design

Compatibility

Designed as an OEM-style replacement and standard-service coupling for 1-1/4 inch nominal steel pipe systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing code requirements. Depressurize and drain the affected pipe section fully before beginning work. Follow the manufacturer torque sequence for the coupling hardware to ensure an even, leak-free seal around the pipe circumference. Do not install on pipe materials or outside diameters outside the rated range for this coupling.
