Midland Industries 844225 Spring Loaded T-bolt Hose Clamp

Product Description

The MIDLAND INDUSTRIES 844225 is a spring loaded T-bolt hose clamp constructed from 300 series stainless steel. It maintains consistent clamping pressure by compensating for thermal expansion and contraction in hose assemblies, making it well suited for high-vibration and temperature-cycling environments. The clamp spans a minimum diameter of 2.25 inches and a maximum diameter of 2.56 inches, with a band width of 0.75 inches and a band thickness of 0.025 inches. Rated to 150 inch-pounds of torque, it delivers reliable, repeatable clamping force without over-tightening. Licensed HVAC technicians, plumbers, and diesel service professionals routinely specify this type of clamp where hose retention integrity is critical.

This clamp is designed for use with air intake and coolant adapter applications. The spring loaded design is particularly effective in under-hood and engine compartment installations where temperature swings cause hose materials to expand and contract repeatedly. It is appropriate for both light commercial and heavy-duty service scenarios where a standard worm-drive clamp would lose preload over time.

Key Features

• 300 series stainless steel construction resists corrosion in wet and chemically aggressive environments
• Spring loaded tension automatically compensates for hose expansion and contraction
• Minimum clamp diameter of 2.25 inches, maximum of 2.56 inches
• Band width of 0.75 inches and band thickness of 0.025 inches for consistent contact surface
• 150 inch-pound torque rating ensures controlled, repeatable clamping force
• T-bolt drive design allows tool-based installation without damaging hose material

Compatibility

Suitable for use with air intake and coolant adapter hose connections requiring a clamp inside diameter range of 2.25 inches to 2.56 inches.

Installation Notes

Installation is performed by qualified mechanical or HVAC technicians using standard hand tools or a nut driver sized to the T-bolt head. Depressurize and allow the system to cool fully before removing or replacing any hose clamp on a coolant or air intake circuit. Do not exceed the 150 inch-pound torque rating, as over-torquing can damage the hose bead or clamp band. Verify hose seating is uniform around the full circumference before applying final torque.
