Worm-Gear Hose Clamps, Pack of 10

These worm-gear hose clamps secure hose connections in automotive and industrial fluid systems. Each clamp uses an interlocked band design with rectangular slots for even tightening. The package contains ten clamps ready for installation.

Suited for 1 in to 3 in hose diameters

They fit hoses with a minimum diameter of 1 in and a maximum of 3 in, making them useful for coolant, intake and vacuum lines. Buyers needing clamps for smaller or larger hose sizes should look at other SAE ranges.

SAE 40 size with 35 in-lb install torque

The SAE 40 designation and 35 in-lb installation torque define the clamping force and tool setting required. This single specification confirms whether the clamp matches the joint design.

Questions about this item

What comes in the pack and is any tool required?

The pack contains ten SAE 40 worm-gear clamps made from 201 stainless steel band and housing with a 305 stainless steel screw. A 5/16 in hex driver or socket is needed to reach the 35 in-lb install torque.

How do I pick the right clamp for my hose?

Choose this SAE 40 size when the hose outside diameter falls between the 1 in minimum and 3 in maximum clamp diameters; the 1/2 in band width and .022 in thickness suit standard automotive and industrial hose walls.

What does the 35 in-lb torque figure mean when I am tightening the clamp?

It is the maximum recommended tightening torque for the 5/16 in screw; exceeding it can strip the threads or distort the 201 stainless band, so use a torque wrench set to 35 in-lb for a secure, repeatable seal.
