The SMITH - BLAIR 245-00040003-000 is a 1-bolt stainless steel pipe repair clamp designed for sealing leaks and making emergency or permanent repairs on pipes with a 4-inch outside diameter. The stainless steel construction resists corrosion, making it suitable for use in wet, buried, or chemically active environments. A single-bolt design simplifies installation while maintaining a secure seal. This clamp is installed by licensed plumbers, pipefitters, and utility maintenance crews working on water, wastewater, and general service piping systems.
This repair clamp is used on residential and commercial piping applications where a fast, reliable seal is needed on a 4-inch OD pipe. Common install scenarios include water main repairs, service line patches, and municipal or industrial distribution system maintenance. The clamp fits around the damaged section of pipe and compresses a gasket against the pipe surface to stop leaks without cutting or replacing the full pipe section.
Designed as an OEM-style repair clamp for pipes with a 4-inch outside diameter in water, wastewater, and general service piping applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing codes. Shut off and depressurize the affected line before applying the clamp. Clean the pipe surface in the repair area to ensure proper gasket contact and a reliable seal. Do not overtighten the bolt beyond the gasket manufacturer's recommended seating point, as overtightening can distort the gasket and compromise the seal.
