Midland Industries M8S-122 T-bolt Hose Clamp 122-130 Mm

Product Description

The MIDLAND INDUSTRIES M8S-122 is a standard T-bolt maxi hose clamp designed to secure hose connections in high-demand fluid and air transfer applications. Built from 301 stainless steel, this bolt-drive clamp delivers corrosion resistance and consistent clamping force across its working range of 122 mm minimum to 130 mm maximum clamp diameter. The 8 mm bolt drive provides reliable torque application with standard tooling. At 0.355 pounds and a band width of 0.94 inches, it is sized for medium-to-large diameter hose assemblies. Plumbers, HVAC technicians, and industrial pipefitters install this type of clamp where worm-drive clamps lack the clamping strength required.

This clamp is suited for residential and commercial installations involving large-diameter hoses, ducting connections, and fluid transfer lines where a secure, uniform seal is critical. The T-bolt design distributes clamping load evenly around the hose circumference, making it appropriate for higher-pressure applications or situations where vibration could loosen a standard worm-drive clamp. It fits hoses with an outside diameter falling between 122 mm and 130 mm.

Key Features

• 301 stainless steel construction resists corrosion in wet and chemically active environments
• T-bolt bolt-drive mechanism provides greater clamping force than standard worm-drive clamps
• Working diameter range of 122 mm minimum to 130 mm maximum suits medium-to-large hose assemblies
• 8 mm bolt accepts standard hex or socket tooling for field installation
• Band width of 0.94 inches distributes load to reduce hose deformation

Compatibility

Designed as an OEM-style replacement or new-installation T-bolt maxi hose clamp for applications requiring a 122 mm to 130 mm clamp diameter range on large-bore hoses and ducting connections.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial pipefitters using a standard hex socket or wrench on the 8 mm bolt. Depressurize and drain the line or shut off airflow before removing any existing clamp. Position the clamp so the band sits fully on the hose bead without overlapping fittings, then tighten the bolt evenly. Follow applicable IPC or system manufacturer torque guidance for the hose material in use.
