Value Collection MS01B64216 Worm Gear Clamp Sae 128

Product Description

The VALUE COLLECTION MS01B64216 is a worm gear clamp rated SAE size 128, designed to secure hose, tubing, and flexible duct connections across a wide range of pipe and fitting diameters. The clamp accepts diameters from 2.5 inches to 8.5 inches, making it well suited for large-diameter applications in HVAC, plumbing, and general mechanical systems. The band is constructed from grade 201 stainless steel and carbon steel, offering corrosion resistance appropriate for both wet and dry service environments. The 0.5-inch-wide band provides consistent clamping force around the full circumference of the connection. Licensed trades and maintenance professionals install this type of clamp wherever a reliable, adjustable mechanical seal is required.

This clamp is used in residential and light commercial applications where hose-to-fitting or flexible-duct-to-collar connections must be secured against vibration, pressure, or thermal cycling. Typical install scenarios include HVAC flexible duct connections, radiator hose service, coolant line repair, and plumbing drain connections. The wide diameter range reduces the need to stock multiple sizes for jobs involving varied pipe or fitting outside diameters.

Key Features

• SAE size 128 worm drive design provides positive, adjustable clamping torque
• Diameter range of 2.5 inches to 8.5 inches covers a broad set of large-bore applications
• Grade 201 stainless steel and carbon steel band construction for corrosion resistance
• Band width of 0.5 inches distributes clamping load evenly around the connection
• Single-piece worm gear mechanism allows tool-free hand positioning before final tightening

Compatibility

Designed as an OEM-style replacement or service clamp for any hose, flexible duct, or tubing assembly with an outside diameter between 2.5 inches and 8.5 inches requiring SAE 128 worm gear clamping.

Installation Notes

Installation is performed by placing the clamp over the hose or flexible duct before seating it onto the fitting, then tightening the worm screw with a flathead or hex driver to the appropriate snug torque for the application. Always de-pressurize or shut off flow in the line before removing or installing clamps on live systems. For HVAC flexible duct applications, verify that the connection meets local mechanical code requirements for duct sealing. Do not overtighten on soft or thin-wall hose materials, as excess clamp force can damage the hose wall.
