The 9/16" - 1 1/16" Stainless Steel (10/Box) (530065) hose clamp will help to tighten the connection between the two hoses. The loose end will fit into a small gap between the band and the captive screw. When you turn the screw, it acts as a worm drive, drawing the threads of the band tighter around the hose (or when screwed in the opposite direction, to loosen). They can also be used similarly as a simple means of transmitting small amounts of power. This hose clamp secures a hose over a fitting. It prevents fluid from leaking at the connection by clamping the hose down. Popular attachments include everything from boat engines to pipe fittings. Key Features: Used in a wide range of industries to secure the transportation of products, liquids, gases, and chemicals. Because of their ease of use, effectiveness, and adaptability, they are extremely popular. Ideal for attaching flexible hoses to solid fittings.
