Quick Release Hose Clamp

Reusable and quite easy to take on and off, the quick release hose clamp is mainly geared towards light-duty, low-pressure hose clamping jobs. It is typically fitted in the air outlet of a central air conditioning system.

Features of Quick Release Hose Clamp
All basic functions aside, this screw band clamp can adjust its opening and tightening torque according to the diameter of the hose to be clamped. It can be opened to be fitted over a wide range of hose sizes, unlike traditional worm gear hose clamps that can only be tightened with a wrench.

Steel band, housing, saddle, and screw can be made of different materials, the most popular being W1, W2, and W4.
