Bk 160-005 Compression Galvanized Coupling 1 in X 4.5 in

Product Description

The BK 160-005 is a compression-style galvanized coupling designed for joining or repairing pipe sections without threading or soldering. Built with a long-pattern, hydroformed steel body, it delivers structural rigidity and corrosion resistance in demanding wet environments. The double-tapered rubber gasket creates two independent seals at each end, reducing leak risk under pressure. A metal friction ring locks the gasket in place during assembly. Rated up to 125 psi at 210 degrees F, this coupling suits high-temperature and high-pressure service lines. Plumbers and pipefitters install this fitting in repair and retrofit applications where fast, reliable connections are required.

The BK 160-005 is sized to fit the outside diameter of 1-inch Schedule 40 iron pipe or 1-inch Schedule 40 PVC pipe, making it a versatile option across mixed-material piping systems. At 4.5 inches in length, the long-pattern body provides added grip and gasket surface, which is especially useful in repairs where pipe ends may be slightly irregular or worn. This coupling is suited for residential and light commercial plumbing systems, including water distribution, drain lines, and general service piping.

Key Features

• Hydroformed steel body with galvanized finish for corrosion resistance
• Long-pattern design provides extended contact area for secure fitment
• Double-tapered rubber gasket delivers two seals at each pipe end
• Metal friction ring holds gasket position during and after installation
• Rated to 125 psi at 210 degrees F for high-temperature service
• Fits outside diameter of Schedule 40 iron pipe and Schedule 40 PVC

Compatibility

Sized to fit the outside diameter of 1-inch Schedule 40 iron pipe and 1-inch Schedule 40 PVC pipe. Suitable as a repair or transition coupling in plumbing systems using these standard pipe schedules.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters. Shut off the water supply and depressurize the line completely before removing any existing fittings or cutting pipe. Ensure pipe ends are clean, free of burrs, and cut square before seating the coupling. Verify final assembly torque and connection integrity against local plumbing code requirements, including IPC standards where applicable.
