Smith-blair BAKCOUP3 Standard Coupling 3 in Steel Pipe

Product Description

The SMITH-BLAIR BAKCOUP3 is a standard pipe coupling designed for use with 3-inch steel pipe. It provides a reliable mechanical connection between pipe sections, joining or repairing lines without welding. This type of coupling is commonly used in water distribution, industrial piping, and mechanical systems where a fast, field-installable joint is required. Licensed plumbers and pipefitters install this fitting as part of new construction or repair work on steel pipe systems.

The BAKCOUP3 is suited for 3-inch steel pipe applications in both commercial and industrial settings. Typical use cases include water mains, fire protection piping, and process lines where a leak-resistant, bolted coupling connection is needed. The coupling allows for slight angular deflection and pipe-end irregularities, making it practical for field repairs and tie-in connections.

Key Features

• Designed for 3-inch nominal steel pipe
• Standard coupling configuration for joining or repairing pipe sections
• Mechanical assembly eliminates field welding
• Accommodates minor pipe-end variations common in field conditions
• Suitable for water distribution and industrial piping applications

Compatibility

Designed as an OEM-style replacement coupling for standard 3-inch steel pipe systems in commercial and industrial plumbing and piping applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable plumbing codes such as the IPC. Depressurize and drain the line completely before disassembling any pipe section or installing the coupling. Follow the manufacturer torque sequence for all bolted components to ensure an even, leak-free seal. Do not exceed the rated working pressure for this coupling type.
