Slotted American Style Worm Gear Hose Clamps are the most commonly used hose clamps because they are economical and reusable. They are made from 301SS, are available in 8mm & 12.7mm widths, in sizes from 6-16 to 59-83mm clamp ranges.

Full Size 9/16" Standard Worm Gear Clamps are the most versatile clamps with a wide range of applications. Parts listed on this page are a Full Size design, made from 201/301 stainless steel with a 5/16" plated carbon steel hex-head screw. The wider 9/16" band width provides 12-1/2% more sealing surface area than conventional 1/2" bands.

Full Size 9/16" Industrial Worm Gear Clamps are all stainless steel construction, available in a 3/8" or 5/16" hex-head 410 grade stainless steel screw design.

Full Size Industrial 9/16" 201/301SS Worm Gear Clamps have 9/16" band width, are IAPMO listed with band, housing and screw all made from high-nickel grade stainless steel. They are ideal for plumbing, industrial, hardware, in-ground and other applications requiring additional resistance to corrosion.

Combo-Hex 9/16" Worm Gear Clamps are the clamps professional mechanics choose most often. They have a 3/8" safety collared hex screw and a 9/16" wide band and housing.

These 5/8" Hi-Torque Heavy Duty Marine Worm Gear Clamps are guaranteed to withstand over 4-times the SAE standard requirements for worm gear clamps, and are approved for Marine use. Their heavy-gauge housing is orbitally riveted to a unique saddle, designed to keep 8 screw threads simultaneously engaged in the band. Coupled with their wider and thicker band (0.625" x 0.028"), this provides exceptional torque drive and 3-times the strength of comparable clamps. These clamps are ideal for applications where conventional clamps are inadequate, and can even replace the need for double and triple clamping.

They are made from 100% 316 Stainless Steel, or 301/304 SS Band, Housing & Saddle with 305 SS Hex-Head Slotted Screw.

Aero-Seal® Hose Clamps are the original stainless steel worm gear clamps. The 4-piece, heavy duty Quadra-Lock design allows more tightening torque at band perforations. A wider 9/16" band adds greater strength. Aero-Seal clamps are Marine grade 301SS and are also used in aircraft and heavy duty industrial applications.

Heavy Duty 5/8" Worm Gear 410SS premium clamps are designed for high vibration and stubborn leakage applications such as industrial machinery, heavy truck, farm and off-road equipment engines. They feature an extra wide 5/8" band and a wide profile housing that provides maximum engagement of screw threads to band.

These Heavy Duty 5/8" Marine Worm Gear Clamps are designed to provide high vibration and leakage resistance in marine applications involving soft hoses, and are all Marine grade stainless steel construction.

These Heavy Duty Extended Range 5/8" Worm Gear Clamps are designed to provide extended clamping ranges in applications where high vibration and stubborn leakage are a problem. They feature an extra-wide band and housing, extra notches for larger working diameters, and 5 sizes provide clamping ranges from 1-1/4" to 10-1/8".

These Mini Marine Worm Gear Clamps are made of high quality Marine-Grade Stainless Steel. Streamlined & lightweight, they are ideally suited for tight-fitting, hard to reach small diameter applications in corrosive environments. Their 5/16" Band, Housing & Saddle are made from either 301/304 or 316 Stainless Steel, with a 305 or 316 Stainless Steel Slotted Hex Screw. These tiny clamps create high sealing pressure with only 10-15in./lbs. of installation torque. These Miniature Worm Gear Clamps are used for air, fuel and transmission lines.

These 1/2" Power-Seal® Worm Gear Clamps are made of high quality stainless steel. The interlocking "square knot" design will not pull apart. This design enables higher sealing pressure even at lower applied torque ranges, such as installing with a screwdriver. Power-Seal Clamps are general purpose and suited for heater and coolant hoses, as well as air intake & bilge pump lines in corrosive and non-corrosive environments. They are available in a variety of stainless steel grades and finishes with 5/16 slotted hex head screw.
