Yellow Zinc Plated Spiral Hose Clamp

A Yellow Zinc Plated Spiral Hose Clamp is an adjustable, light-duty fastening device characterized by its unique spiral-wound double-wire band and yellow chromate finish. It serves as an economical solution for securing low-pressure hoses and ducts where moderate vibration resistance and basic environmental protection are required.

Key Features of Spiral hose clamp

Material & Finish

Band: Constructed from two parallel steel wires that are spirally wound around a central axis, forming a flexible yet cohesive band. This spiral construction provides greater flexibility and conformability than a simple parallel double-wire clamp.

Finish: Coated with a Yellow Zinc (Zinc Chromate) plating. This finish offers better corrosion resistance than standard zinc plating by forming a protective chromate conversion layer. The distinctive yellow color also provides a visual identifier and a slightly more decorative appearance.

Screw & Housing: Features a standard zinc-plated steel screw housed in a simple stamped saddle. The screw threads engage directly with the gaps in the spiral wire winding.

Working Principle

Operates on a modified worm-drive principle. Turning the screw causes the housing to advance along the helical path created by the spiral winding of the wires.

This design allows for continuous 360-degree tightening and provides a more uniform pressure distribution than non-spiral wire clamps, as the spiral band acts more like a solid, flexible strip.

Advantages of Spiral hose clamp

High Flexibility & Conformability: The spiral-wound band can easily adapt to irregular, tapered, or out-of-round surfaces, ensuring better contact.

Good Vibration Resistance: The combination of the flexible band and the worm-drive mechanism helps maintain tension in vibrating environments better than many light-duty clamp types.

Improved Load Distribution: Offers more uniform circumferential pressure than standard double-wire clamps, reducing the risk of hose pinching or damage.

Enhanced Corrosion Protection: The yellow zinc chromate plating provides superior resistance to white rust and general corrosion compared to plain electroplated zinc.

Cost-Effective: Remains an economical alternative to solid-band stainless steel clamps for suitable applications.
