Product Description

Stainless Constant Tension Hose Clamps: Reliable and Durable Solution for Secure Hose Connections

Stainless Constant Tension Hose Clamps are engineered to provide a secure, long-lasting seal for hoses on pipes, ensuring optimal performance in demanding applications. Designed with a high-quality stainless steel band, these clamps feature parallel angled slots near the free end, allowing for precise adjustment. The housing, attached to the first end, incorporates an adjustment screw that remains mostly enclosed, enhancing safety and durability. The screw's thread engages with the slots, enabling easy tightening while a built-in helical spring maintains consistent pressure, compensating for hose relaxation or thermal expansion.
