Midland Industries 844275 Spring Loaded T-bolt Hose Clamp

Product Description

The MIDLAND INDUSTRIES 844275 is a spring loaded T-bolt hose clamp engineered for secure, vibration-resistant connections in demanding fluid and air handling applications. Constructed from 300 series stainless steel, it maintains clamping tension across a diameter range from 2-3/4 inches minimum to 3.06 inches maximum. The band measures 3/4 inches wide and 0.025 inches thick, with a rated torque capacity of 150 inch-pounds. The integrated spring mechanism compensates for hose expansion and contraction caused by thermal cycling, reducing the need for retorquing. HVAC technicians, diesel mechanics, and plumbing professionals install this clamp where a standard worm-drive clamp cannot maintain consistent preload under pressure or temperature swings.

This clamp is specifically suited for air intake and coolant adapter connections, making it a practical choice in engine cooling systems, forced-air HVAC ducting transitions, and industrial fluid transfer lines. The T-bolt design distributes clamping force evenly around the hose circumference, which is important on silicone and reinforced rubber hoses that can deform under uneven load. It fits hose and fitting assemblies with outside diameters between 2-3/4 inches and 3.06 inches. The spring loaded tension feature makes it well suited for installations where thermal cycling or vibration would otherwise loosen a static clamp over time.

Key Features

• Spring loaded T-bolt design maintains constant radial tension without manual retorquing
• 300 series stainless steel construction resists corrosion in wet and high-heat environments
• Clamp diameter range: 2-3/4 inches minimum to 3.06 inches maximum
• Band width of 3/4 inches and thickness of 0.025 inches for broad, even clamping surface
• Rated to 150 inch-pounds torque for positive seating on reinforced hoses
• Suitable for air intake and coolant adapter applications

Compatibility

Designed for use with air intake and coolant adapter assemblies requiring a clamp diameter between 2-3/4 inches and 3.06 inches. Typical applications include silicone and reinforced rubber hoses in HVAC, diesel engine cooling, and industrial fluid transfer systems.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or qualified mechanics. Always depressurize the system and allow coolant or process fluid to cool before removing or repositioning any hose clamp. Position the clamp band fully over the hose bead or fitting retention groove before torquing the T-bolt fastener. Do not exceed the rated torque value stamped or listed for the clamp, as overtightening can deform the hose or damage the band.
