Midland Industries 844363 Spring Loaded T-bolt Hose Clamp

Product Description

The MIDLAND INDUSTRIES 844363 is a spring loaded T-bolt hose clamp designed for secure, vibration-resistant connections in demanding fluid and air transfer applications. Built from 300 series stainless steel, it delivers strong corrosion resistance in wet or high-temperature environments. The clamp spans a minimum diameter of 3.63 inches to a maximum of 3.94 inches and features a band width of 0.75 inches with a band thickness of 0.025 inches. A maximum torque rating of 150 inch-pounds ensures a reliable, leak-free seal. HVAC technicians, plumbers, and mechanical contractors install this clamp where a consistent clamping load is required even as hose materials expand and contract with temperature changes.

This clamp is rated for use with air intake and coolant adapter connections. The spring loaded design maintains constant radial tension on the hose, making it well suited for underhood cooling lines, charge air systems, and similar high-vibration or thermally cycled installations found in both residential mechanical systems and light commercial equipment. It is appropriate wherever a standard worm-drive clamp would lose tension over time due to hose compression set or thermal cycling.

Key Features

• Spring loaded T-bolt design maintains constant clamping load through thermal expansion and hose compression set
• 300 series stainless steel band and hardware for corrosion resistance in wet and high-temperature environments
• Clamp diameter range: 3.63 inches minimum to 3.94 inches maximum
• Band width of 0.75 inches and band thickness of 0.025 inches for even load distribution
• Maximum torque rating of 150 inch-pounds
• Suitable for air intake and coolant adapter connections

Compatibility

Designed for use with air intake and coolant adapter hose connections where a spring loaded T-bolt clamp in the 3.63 to 3.94 inch diameter range is specified.

Installation Notes

Installation should be performed by a qualified HVAC technician, plumber, or mechanical contractor. De-pressurize and drain the system before removing or installing hose clamps on coolant or fluid lines. Use a calibrated torque tool and do not exceed the 150 inch-pound maximum torque rating to avoid band deformation or hose damage. Confirm the hose and adapter are fully seated before tightening the T-bolt fastener.
