Midland Industries 844375 Spring Loaded T-bolt Hose Clamp

Product Description

The MIDLAND INDUSTRIES 844375 is a spring loaded T-bolt hose clamp built from 300 series stainless steel. It maintains consistent clamping force on hose connections by using a spring-tensioned T-bolt design that compensates for hose expansion and contraction during temperature cycles. The clamp band measures 0.75 inches wide and 0.025 inches thick, with a minimum clamp diameter of 3.75 inches and a maximum clamp diameter of 4.06 inches. Rated to 150 inch-pounds of torque, this clamp is suited for HVAC, automotive, and industrial service work where vibration or thermal cycling would cause a standard worm-drive clamp to loosen over time.

This clamp is specified for use with air intake and coolant adapter connections. It is commonly installed on silicone or rubber hose couplings in applications where maintaining a consistent seal under variable pressure and temperature is critical. Service technicians working on forced-air systems, intercooler piping, and coolant circuit hoses use this style of clamp as a direct replacement for OEM spring band or standard T-bolt clamps where the added spring compensation is needed to prevent leaks.

Key Features

• Spring loaded T-bolt design maintains constant clamping force through thermal expansion and contraction cycles
• 300 series stainless steel construction resists corrosion in wet and high-temperature environments
• Minimum clamp diameter of 3.75 inches and maximum of 4.06 inches for a precise fit on standard large-bore hose couplings
• Band width of 0.75 inches distributes clamping load evenly across the hose surface
• Rated to 150 inch-pounds of torque for reliable sealing without over-compression
• Suitable for air intake and coolant adapter service per manufacturer specification

Compatibility

Designed for use with air intake and coolant adapter hose connections requiring a 3.75 inch to 4.06 inch clamp diameter range in 300 stainless steel T-bolt clamp applications.

Installation Notes

Installation should be performed by a qualified technician familiar with hose clamp torque requirements for the specific hose and fitting material in use. De-pressurize and allow the system to cool fully before removing or installing any clamp on a coolant or air intake circuit. Use a calibrated torque tool and do not exceed the 150 inch-pound rated torque to avoid damaging the hose or clamp band. Verify clamp position is centered on the hose bead or coupling before final tightening.
