Midland Industries 844356 Spring Loaded T-bolt Hose Clamp

Product Description

The MIDLAND INDUSTRIES 844356 is a spring loaded T-bolt hose clamp built for secure, vibration-resistant connections in demanding under-hood and fluid system applications. Constructed from 300 series stainless steel, this clamp maintains consistent radial pressure across the clamping range of 3.56 to 3.88 inches in diameter. The band measures 0.75 inches wide and 0.025 inches thick, with a rated torque of 150 inch-pounds. The spring loaded design compensates for thermal expansion and contraction, reducing the risk of loosening over time without manual retorquing. Licensed HVAC technicians, plumbers, and diesel service professionals commonly specify this style of clamp where standard worm-drive clamps are not adequate for the application.

This clamp is suited for use with air intake systems and coolant adapter connections, making it a practical choice in automotive, heavy equipment, and light commercial HVAC installations where silicone or rubber hose transitions require a high-clamping-force solution. The spring tension feature makes it especially useful in environments with significant temperature cycling, where hose materials expand and contract repeatedly. It is appropriate for both initial installation and service replacement work.

Key Features

• Spring loaded design maintains constant radial clamping pressure without manual retorquing
• Clamping range of 3.56 to 3.88 inches accommodates standard large-bore hose transitions
• 300 series stainless steel construction resists corrosion in wet and high-temperature environments
• Rated to 150 inch-pounds torque for secure, repeatable installation
• 0.75 inch band width distributes clamping load evenly across the hose bead
• Suitable for air intake and coolant adapter service

Compatibility

Designed for use with air intake and coolant adapter hose connections requiring a minimum clamp diameter of 3.56 inches and a maximum clamp diameter of 3.88 inches.

Installation Notes

Installation should be performed by a qualified technician using a calibrated torque tool to avoid over-tightening the T-bolt hardware beyond the rated 150 inch-pound specification. Ensure the system is depressurized and cooled before removing or installing any hose clamp on coolant or charge-air circuits. Position the clamp band fully over the hose bead and centered on the fitting before applying torque. Follow all applicable equipment manufacturer service procedures and relevant codes during installation.
