Soft-Touch Worm-Drive Hose Clamps

Use these soft-touch worm-drive hose clamps with soft hoses and tubes. An integral smooth inner liner covers up the fastening slots that can cut into soft hoses. There are no bumps under the housing to jeopardize the concentricity of the seal and no laminated coverings to disintegrate under heat, ultraviolet, or corrosive attacks. Meet SAE J1508.

Constant Tension Worm-Drive Hose Clamps

As fluids run through your hose, thermal expansion and contraction will occur. These hose clamps will adjust right along with it, keeping the same tension on your hose.

An integral smooth inner liner also covers up the fastening slots that can cut into soft hoses. There are no bumps under the housing to jeopardize the concentricity of the seal and no laminated coverings to disintegrate under heat, ultraviolet, or corrosive attacks.

Commonly used in marine and burial applications, the all stainless steel design allows these hose clamps to stand up to tough environments. No steel or spot welds to rust, corrode, or rupture.

No-Maintenance Constant-Tension T-Bolt Hose Clamps

No maintenance required - the large spring allows for greater thermal expansion and contraction than a standard hose clamp. Commonly used in charge air cooling systems, for maintaining tension on hoses that experience high temperature and pressure swings. Band is 3/4" wide. Made of stainless steel, except hex nut and spring are plated steel. Meet SAE J1508.
