Smith - Blair 4.61028E+13 Metal Bolted Coupling 2.5 in

Product Description

The SMITH - BLAIR 4.61028E+13 is a metal bolted coupling designed for pipe repair and connection in plumbing, waterworks, and mechanical piping systems. This Quantum-series coupling accommodates pipe outside diameters ranging from 2.84 to 3.35 inches, making it suitable for joining or repairing pipes near the nominal 2.5-inch size range. The bolted design allows field technicians to achieve a secure, leak-resistant mechanical connection without welding or special tooling. Licensed plumbers, pipefitters, and utility maintenance crews are the primary installers of this type of coupling in both above-ground and buried service applications.

This coupling is typically used in residential and light commercial water distribution, irrigation, and industrial process piping where a fast mechanical repair or transition connection is needed. The Quantum metal bolted style is well suited for straight pipe coupling on steel, ductile iron, cast iron, and comparable pipe materials within its stated diameter range. It is particularly useful in repair situations where a damaged pipe section must be sealed quickly without cutting out a long section of pipe.

Key Features

• Accepts pipe outside diameters from 2.84 to 3.35 inches for flexible fitment across nominal pipe sizes near 2.5 inches
• Metal bolted construction provides a durable, high-strength mechanical connection
• Quantum-series design intended for pipe repair and coupling in pressurized piping systems
• No welding required — field-installable with standard hand tools
• Order increment of 1 allows single-unit purchasing for spot repairs

Compatibility

Designed as an OEM-style mechanical coupling for pipes with an outside diameter in the 2.84 to 3.35 inch range, consistent with nominal 2.5-inch pipe in various schedule and material classes.

Installation Notes

Installation is typically performed by licensed plumbers or pipefitters. Shut off and depressurize the line before installing any mechanical coupling. Clean and deburr the pipe ends within the coupling engagement zone before seating the gasket and tightening the bolts. Follow applicable IPC and local plumbing code requirements for buried or pressurized service, and torque fasteners evenly in an alternating pattern per the manufacturer's printed installation sheet supplied with the product.
