T-Bolt Clamps — High-Performance Clamping for Demanding Applications

Murray Corporation manufactures T-bolt clamps that deliver superior holding power, even pressure distribution, and vibration resistance for the most demanding industrial, automotive, and commercial applications. Our TB series T-bolt clamps are engineered to provide reliable, leak-free connections where standard hose clamps cannot meet performance requirements.

How T-Bolt Clamps Work

A T-bolt clamp uses a T-shaped bolt and nut to draw a wide stainless steel band tightly around the hose or tube connection. As the nut is tightened, the bolt pulls the band into a uniform circle, applying consistent 360-degree clamping pressure across the full width of the band. This mechanism delivers significantly higher clamping force than screw-type worm drive clamps and maintains that force more reliably under vibration, pressure cycling, and thermal expansion.

The T-bolt design also allows for precise torque-controlled installation. By tightening the nut to a specified torque value, installers can achieve repeatable clamping force across production runs, reducing variability and improving connection reliability.

Key Features and Benefits

Murray's TB series T-bolt clamps offer high clamping force for secure connections on pressurized and large-diameter hoses. The wide band distributes load evenly to prevent hose damage. Stainless steel construction provides corrosion resistance for harsh environments. The design resists loosening caused by vibration and mechanical shock. Torque-controlled installation ensures consistent, repeatable performance. And our comprehensive size range fits applications from small turbo connections to large industrial hoses.

Applications

T-bolt clamps are the preferred choice for applications requiring high clamping force and vibration resistance, including turbocharger and intercooler hose connections, heavy-duty truck air intake and coolant systems, automotive performance and racing applications, industrial hydraulic and pneumatic hose connections, marine engine and exhaust systems, and off-highway and construction equipment fluid lines.

Murray Corporation manufactures T-bolt clamps in standard, spring-loaded, and heavy-duty configurations. Contact us today or request a quote to discuss the right T-bolt clamp for your application.
