Value Collection MS09B2645 Constant Torque Hose Clamp

Product Description

The VALUE COLLECTION MS09B2645 is a constant torque hose clamp built for secure, vibration-resistant connections on hose assemblies with an outside diameter range of 1.024 to 1.75 inches. Unlike standard worm gear clamps, a constant torque design uses a spring-loaded band that automatically compensates for thermal expansion and contraction, maintaining consistent clamping pressure across temperature cycles. The band is 5/8 inches wide and constructed from stainless steel, with a Grade 301 stainless steel screw for corrosion resistance. At 0.03 pounds, this is a compact, single-piece clamp suited for tight quarters in HVAC, plumbing, and fluid-transfer applications.

This clamp is a common choice for refrigerant hose connections, coolant lines, flexible duct collars, and plumbing supply connections where thermal cycling or mechanical vibration would cause a standard clamp to loosen over time. It is well-suited for both residential and light commercial service work where maintaining a leak-free seal over repeated heating and cooling cycles is critical. A single clamp is included per package.

Key Features

• Constant torque spring-loaded band maintains clamping pressure through thermal expansion and contraction cycles
• Fits hose outside diameters from 1.024 to 1.75 inches (fractional range: 1 to 1-3/4 inches)
• 5/8 inch band width distributes clamping load evenly across the hose surface
• Stainless steel construction with zinc finish for corrosion resistance
• Grade 301 stainless steel screw for reliable torque application
• Lightweight at 0.03 pounds, suitable for confined installation spaces

Compatibility

Designed as an OEM-style replacement or service clamp for hose assemblies with outside diameters between 1.024 and 1.75 inches, typical in HVAC, plumbing, and fluid-handling systems.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or pipefitters using a standard flat-blade or hex screwdriver depending on the screw head type. Always depressurize the line and shut off fluid flow before removing or installing a hose clamp. Ensure the hose is fully seated on the fitting before tightening. Do not overtighten beyond the clamp design limit, as this can damage the hose or fitting.
