These All Stainless German Style Multi-Range Worm Gear Clamps are ideal for applications with high mechanical loads. Each clamp can be used on multiple sizes of hoses. Their patented asymmetric construction provides even distribution of forces and safe assembly, with an embossed inner band for added hose protection. They have superior tensile strength, high fracture torque & even distribution of tension force.

• 9 mm Wide in 8-230 mm Clamp Ranges
• 12 mm Wide in 16-320 mm Clamp Ranges

Torro® Worm Gear Clamps with Integrated Springs add an automatic self-adjusting constant tension to the 9 or 12mm asymmetric worm drive clamp. Tightening the screw loads the spring with enough clamping force to ensure a long-lasting automatic re-tensioning effect, even in very low temperatures. The self-adjusting radial clamping force achieved makes these ideal for applications under extreme temperature changes (e. g. charged air) or for the retention of hoses with a tendency of "creeping" (hose relaxation). They are particularly suited to connecting cooling and heating hoses.

Heavy Duty All Stainless Swedish Style Embossed Worm Gear Clamps are designed for the high end of the Marine market such as OE yacht builders and the marinas and distributors that service them.

This clamp is made of all AISI 316 high tensile strength stainless steel. It has one of the highest clamping force ratings of all worm gear style clamps due to the fine thread pitch and riveted housing. Band width is 12mm, unless otherwise noted. Its band is non-perforated and rolled up at the edges, to protect your hoses.

Alu-Zinc Euro-Style Worm Gear Clamps, with their smooth inner band surface and curled edges for extra hose protection, were developed specifically for the aftermarket exclusively for indoor use. The re-designed head and band help provide increased band power and perfect tightness. The high degree of security reserves assures maximum protection against overtightening.

9 mm Wide Band Worm Gear Clamps are an ideal choice for uniform hose sealing when connecting automotive fuel lines, as well as fuel lines for the white goods industry, sanitary facilities, machine construction, and the like. Their asymmetrical design provides even distribution of force and safe assembly. Hoses are protected by the curved band edges, and by the interior of the band, which is either smooth or stamped. They have a wide clamping range, and are available in several different materials and accessory options to suit your application needs.

These 1/2" Euro-Seal Embossed Marine Worm Gear Clamps have an embossed band with smooth underside and band edges to eliminate hose abrasion and extrusion. They are available in a variety of materials including 100% 316 Stainless Steel, and can be used in above water marine and some underground applications.

These Aero-Seal® Liner Marine Worm Gear Clamps protect soft silicone hose even in Marine environments. Extensions of the band itself form the integral liner covering the worm gear slots to protect the hose from extrusion & shear without shifting. There are no bumps or laminates or coverings that could deteriorate over time. Silicone hoses can last up to 10 years, and their clamps must be as durable. These clamps are 4-piece heavy duty Quadra-Lock construction in all stainless steel. They are available in 1/2", 9/16", & 5/8" band widths, and are used for Coolant, Fuel, Air Intake & Turbo Sleeves in Marine environments.

Constant-Torque® Marine Worm Gear Clamps use a patented Belleville spring mechanism to automatically adjust the clamp diameter in response to changes in environmental and operational temperatures. The 9/16" wide Aero Seal design is for smaller diameters and is torque rated for 30-70in./lbs. The 5/8" wide Heavy Duty design is for larger diameters and is torque rated 50-125 in./lbs. Both designs are marine quality stainless steel, and are listed here for your convenience.

These Heavy Duty 5/8" Lined Marine Worm Gear Clamps are designed to provide high vibration and leakage resistance in marine applications involving soft hoses, and are all Marine grade 300 stainless steel construction. This series has a protective liner to prevent extrusion and shearing of the hose through band notches. The extended band prevents the liner from skewing during installation.

These Heavy Duty High Torx® Worm Gear Clamps are used in areas where extremely high band tensile forces and destructive torques are required. They have more robust housing for additional strength over the standard worm drive clamp. They deliver high band tensile force, even tension force distribution, and their fracture torques exceed those of competitive products, greatly increasing the safety of assembly. These clamps are recommended for use in the commercial vehicle sector, in cooling water connections, and air ducts for high and low pressure applications, and are only available in 12mm band width, with or without a constant tension spring insert.
