Adjustable Worm Gear Hose Clamp
This item is an adjustable worm gear hose clamp, commonly referred to as a Jubilee clip. It is constructed from a band of metal, likely stainless steel or galvanized carbon steel, featuring a series of rectangular slots or perforated tracks. The clamp consists of a circular band and a captive screw housing. The screw, often featuring a hex head with a slotted or cross-recess drive, is used to tighten or loosen the band's diameter. Physically, the item shows a metallic, slightly reflective finish typical of industrial hardware. The construction indicates a mechanical fastening purpose, designed to secure a hose over a fitting by compressing it uniformly. Notable features include the integrated worm gear mechanism which provides high clamping force with relatively low input torque. Regarding condition, there appears to be some minor surface oxidation or ‘patina’ consistent with exposure to moisture or age, though the integrity of the gear housing seems intact. These clamps are ubiquitous in automotive, plumbing, and industrial applications, making them difficult to date precisely, though the design has remained a standard since the early 20th century. The quality of the stamped slots and the robustness of the screw housing suggest a standard industrial manufacturing process rather than a precision-grade specialty component.
