5/8” Heavy Duty Worm Gear Clamp – XH Series

Available in 300 series stainless steel, 304 stainless steel, and 316 stainless steel with 5/8” band width.
Screw is longer and has a larger diameter than standard Worm Drive clamps to provide strength under load and to increase the number of threads engaged with the band. This produces a HD Worm Gear Clamp that can withstand higher loads.
Band material is slightly thicker allowing for higher tensile strength providing a stronger clamp capable of producing higher torque ratings.
Ultimate torque is a minimum of 100 in lbs, or 11.3 Nm.
Recommended Installation Torque is 75 in lbs or 8.5 Nm.
Suitable for applications where a heavier duty clamp is necessary.
Other material grades may be available upon request.

XH High Torque Series Clamps — Heavy-Duty Screw Type Clamping

Murray Corporation manufactures the XH high torque series clamps, engineered for applications that demand significantly more clamping force than standard worm drive clamps can deliver. The XH series features a wider band, heavier construction, and a reinforced screw mechanism designed to achieve high torque without band distortion or fastener failure.

Design and Construction

The XH high torque clamp builds on the proven worm drive clamp design but incorporates several engineering enhancements for heavy-duty performance. The extra-wide band distributes clamping force across a larger contact area, improving seal integrity and reducing the risk of hose extrusion under pressure. The heavier gauge stainless steel band resists deformation under the higher torque loads required for demanding applications. The reinforced housing and screw mechanism prevent distortion during high-torque installation, ensuring consistent performance.

Key Features and Benefits

Murray's XH high torque clamps deliver high clamping force that exceeds standard worm drive clamp capabilities. The wide band distributes load evenly to prevent hose damage and improve sealing. Heavy-gauge stainless steel construction withstands demanding industrial environments. The reinforced screw mechanism handles high installation torques without stripping or deformation. And the standard worm drive operation allows installation with common tools.

Applications

XH high torque series clamps are used in applications where standard screw-type clamps do not provide sufficient clamping force. Common applications include heavy-duty truck and off-highway vehicle coolant, air intake, and exhaust connections, industrial process piping and fluid transfer systems, marine engine and plumbing connections, mining and construction equipment fluid lines, agricultural pump discharge and irrigation mains, and municipal water and wastewater systems.

The XH series bridges the gap between standard worm drive clamps and T-bolt clamps, providing high clamping force with the adjustability and ease of installation that worm drive users are accustomed to.
