Schlauchschelle

A Schlauchschelle, often translated as hose clamp or hose clip, is a fastening device used to create a tight seal around a flexible hose, typically connecting it to a fitting or another hose. Its primary function is to prevent leaks of fluid or gas under pressure, or to secure a hose against being pulled off.

The most common type of Schlauchschelle is the worm-drive clamp. This design consists of a metal band, usually made of galvanized steel, stainless steel, or sometimes aluminum, with a screw mechanism. The band has a series of perforations or a grooved surface that engages with a worm screw. When the screw is turned, it rotates within a housing, pulling the band tighter and thereby reducing its diameter. This tightening action compresses the hose onto the fitting, creating a leak-proof seal.

Other types of Schlauchschellen exist, including spring-loaded clamps, ear clamps, and wire clamps, each with specific applications and advantages. Spring-loaded clamps are often used in automotive applications where constant tension is required due to temperature fluctuations. Ear clamps are crimped onto the hose and fitting, offering a permanent and tamper-proof solution. Wire clamps provide a strong and durable grip, often used in high-pressure systems.

Schlauchschellen are manufactured in a wide range of sizes to accommodate various hose diameters. They are essential components in numerous industries, including automotive, marine, aerospace, plumbing, and industrial manufacturing, where maintaining secure and leak-free connections is critical. Proper selection and installation of a Schlauchschelle are important to ensure optimal performance and longevity of the connection.
