Midland Industries 842500 Constant Torque Hose Clamp Ss

Product Description

The MIDLAND INDUSTRIES 842500 is a constant torque hose clamp built for applications where vibration, thermal cycling, or pressure fluctuation can cause conventional clamps to lose clamping force over time. Made from 304 stainless steel, this bolt-drive clamp maintains consistent radial pressure across the clamp diameter range of 4-1/4 inches minimum to 5-1/8 inches maximum. At 0.028 inches thick and rated to 130 inch-pounds of torque, it delivers a secure, leak-resistant seal on hoses found in HVAC, plumbing, pool, and mechanical systems. Licensed tradespeople and experienced service technicians are the primary installers.

This clamp is suited for residential and light commercial installations where hose connections are exposed to temperature swings or engine and equipment vibration. The constant torque design compensates for hose compression set and material expansion, making it appropriate for radiator hoses, coolant lines, duct connections, and similar service points. It is driven by a standard 3/8-inch bolt head, compatible with common hand tools and power drivers used in the field.

Key Features

• Constant torque spring design maintains clamping pressure through thermal expansion and vibration cycles
• 304 stainless steel construction resists corrosion in wet and outdoor environments
• Clamp diameter range: 4-1/4 inches minimum to 5-1/8 inches maximum
• Rated torque of 130 inch-pounds for a firm, reliable seal
• 0.028-inch band thickness provides a balance of flexibility and strength
• 3/8-inch bolt drive works with standard hex sockets and nut drivers

Compatibility

Designed as an OEM-style replacement or upgrade clamp for hose connections in the 4-1/4 inch to 5-1/8 inch outside diameter range across HVAC, plumbing, pool, and general mechanical applications.

Installation Notes

Installation is performed by HVAC technicians, plumbers, or mechanical service professionals. Shut off fluid flow and relieve system pressure before replacing any hose clamp. Use a calibrated torque tool where precise clamping force is critical and avoid overtightening, which can cut into hose material. Inspect the hose condition before reinstalling or upgrading to a new clamp.
