Worm gear clamps, pack of ten

These worm gear hose clamps provide adjustable sealing for hose connections across automotive and industrial systems. The interlocked band design distributes clamping force evenly around the circumference. Each clamp is manufactured from 201 stainless steel band and housing with a 305 stainless steel screw. The package contains ten clamps ready for installation.

Installers needing 1-1/4 to 2-1/4 inch range

Mechanics and technicians securing radiator, heater, or intake hoses within the SAE 28 size range will find these clamps fit the application. The 1/2 inch band width and 35 in-lb install torque suit standard hose profiles. Builders requiring a smaller minimum diameter or a different SAE size should select another clamp. The rectangular band slots require a compatible driver for tightening.

SAE 28 size with 1-1/4 inch minimum

The defining specification is the SAE 28 designation, which sets the minimum clamp diameter at 1 1/4 inches and the maximum at 2 1/4 inches. This size determines whether the clamp matches the hose outside diameter in your assembly. Verify the hose dimensions against this range before ordering.

Questions about this item

How much torque should I apply to the 5/16 in screw when tightening the 6728-5 clamp for a permanent installation?

The manufacturer specifies an install torque of 35 in-lb for the worm gear screw; using a torque wrench set to that value helps prevent over-tightening the 201 stainless band.

What size hose or pipe do I need on hand so the SAE 28 clamp fits correctly?

The clamp adjusts from a minimum diameter of 1 1/4 in to a maximum of 2 1/4 in, so the hose outside diameter must fall within that range for a secure seal.

Will the 201 stainless band and 305 stainless screw hold up when reused on older radiator hoses that see coolant temperatures?

Both band and screw are stainless steel grades chosen for corrosion resistance, and the interlocked design with rectangular band slots maintains clamping force through thermal cycles.
