Value Collection MS09D83105 Constant Torque Hose Clamp

Product Description

The VALUE COLLECTION MS09D83105 is a constant torque hose clamp engineered for secure, vibration-resistant hose connections across a range of trade and industrial applications. Spanning a clamping range of 3.25 to 4.125 inches outside diameter and measuring 5/8 inches wide, this clamp maintains consistent radial pressure even as hose materials expand and contract with temperature changes. The band and housing are stainless steel, and the screw is Grade 301/410 stainless steel, providing corrosion resistance in wet or chemically active environments. HVAC technicians, plumbers, and mechanical contractors regularly specify constant torque clamps where standard worm-drive clamps cannot sustain adequate seating force over time.

This clamp is suited for flexible hose connections in residential and light commercial systems where hose assemblies are subject to thermal cycling, pressure surges, or vibration. Typical applications include HVAC condensate drain lines, radiant heating supply and return connections, chiller hose assemblies, and plumbing hose-to-pipe transitions. The 3.25 to 4.125 inch diameter range accommodates a variety of hose sizes commonly found in these systems.

Key Features

• Constant torque design maintains steady clamping pressure through thermal expansion and contraction cycles
• Clamping range: 3.25 to 4.125 inches outside diameter
• Band width: 5/8 inches for broad seating surface and even load distribution
• Full stainless steel construction with Grade 301/410 stainless steel screw for corrosion resistance
• Lightweight at 0.03 pounds — minimal added load on hose assemblies

Compatibility

Designed as a standard constant torque hose clamp for flexible hose outside diameters from 3.25 to 4.125 inches, suitable for HVAC, plumbing, and mechanical piping hose connections within that diameter range.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or pipefitters depending on the system served. Shut off fluid flow and relieve system pressure before removing or installing any hose clamp. A flat-blade or hex driver is typically used to seat the clamp screw — do not overtighten beyond the point of firm hose seating, as constant torque designs are self-regulating within their design range. Follow applicable IPC or IFGC guidelines for hose connection methods in pressurized systems.
