Midland Industries 844338 Spring Loaded T-bolt Hose Clamp

Product Description

The MIDLAND INDUSTRIES 844338 is a spring loaded T-bolt hose clamp built for secure, constant-tension connections in demanding fluid and air handling applications. Manufactured from 300 series stainless steel, it delivers corrosion resistance suitable for coolant and air intake environments. The clamp accommodates hose diameters from 3.38 inches minimum to 3.69 inches maximum, with a band width of 0.75 inches and a band thickness of 0.025 inches. The spring loaded design maintains consistent clamping force as hoses expand and contract with temperature cycling, reducing the need for retorquing after initial installation. Maximum rated torque is 150 inch-pounds. Licensed mechanics, HVAC technicians, and diesel service professionals typically install this clamp type.

This clamp is rated suitable for use with air intake and coolant adapter connections, making it appropriate for both automotive and light industrial plumbing scenarios. Its bolt-drive, spring loaded tension design is commonly specified where vibration or thermal expansion could cause a standard worm-drive or solid T-bolt clamp to loosen over time. The 300 stainless steel construction holds up in wet, oily, and moderate-heat underhood or mechanical room environments.

Key Features

• Spring loaded design maintains constant clamping tension through thermal and vibration cycles
• 300 series stainless steel band and hardware for corrosion resistance
• Clamp diameter range: 3.38 inches minimum to 3.69 inches maximum

• Maximum torque rating of 150 inch-pounds
• Rated for air intake and coolant adapter applications

Compatibility

Suitable for use with air intake and coolant adapter connections on hoses with an outside diameter between 3.38 inches and 3.69 inches.

Installation Notes

Power down or depressurize the system and allow it to cool fully before removing or installing hose clamps on coolant or air intake lines. Position the clamp over the hose before seating the hose onto the fitting, then drive the T-bolt to the rated torque limit using a calibrated torque wrench - do not exceed 150 inch-pounds. Inspect the clamp seat and band for proper alignment before final tightening to avoid band distortion.
