German Type Hose Clamp
German type hose clamps are non-perforated worm-drive clamps used for hose and pipe fastening in automotive, machinery, industrial equipment, and general piping applications. The smooth band helps reduce hose surface damage during tightening, while the screw and housing structure supports more even clamping around the hose.
Yueding supplies German type hose clamps in regular size ranges from 16–50 mm, with material, band width, screw type, surface finish, and packing options available according to your order requirements. If you need bulk orders, mixed sizes, or customer packaging, we can help confirm the clamping range, material grade, structure, surface treatment, and packing details before production.

Supply Capabilities
DIN Reference Structure
Band, Housing, and Screw Fit
In actual assembly, small variations in band width, band thickness, housing position, screw fit, or forming shape can affect how smoothly the clamp tightens. For German type hose clamps, we pay attention to the fit between the band, housing, and screw, because these parts directly affect tightening feel and clamping stability.
Smooth Non-Perforated Band
The smooth non-perforated band is not only an appearance feature. During tightening, rough edges, poor forming, or uneven pressure can scratch the hose surface or create local stress points. This structure is especially useful for softer rubber hoses or applications where hose surface protection is important.
Material Options and Large-Size Production Handling
Yueding can supply common material grades such as W1, W2, W4, and W5 for different corrosion resistance, strength, and cost requirements. For larger German type hose clamps, semi-automatic production with manual support may be used to match different diameter ranges and structure requirements, especially when band forming or housing assembly needs more flexible process control.
Related German-Type Hose Clamp Options
With Handle
Designed for applications that require frequent opening or manual adjustment. Handle versions are available in stainless steel or colored plastic options.
Offset Compensation
The offset structure helps compensate for hose expansion, contraction, or position deviation during tightening. It is suitable for applications where more even clamping pressure is required.
Clamp Head
Clamp heads can be supplied separately for custom size production or material modification. They are compatible with standard German type hose clamp band structures.
Bridge Type
Designed for spiral-reinforced hoses. The bridge structure helps the clamp fit over the hose spiral and tighten more evenly around the connection area.
Automated Production Backed by Factory Strength
Yueding’s factory covers over 20,000 square meters and is equipped with automated and semi-automated production facilities for German type hose clamps and related metal components. With more than 200 full-time staff, including experienced engineers and production teams, we support stable batch production, mixed-size orders, and long-term supply needs.
Our products are exported to more than 110 countries, with annual sales exceeding USD 10 million. Certified under ISO 9001, ISO 45001, IATF 16949, and RoHS, Yueding provides reliable manufacturing and quality support for automotive, industrial hose, machinery, and piping applications.
Product Questions & Answers
What is a German-style hose clamp? How does it differ from the American-style hose clamp?
Unlike the American-style hose clamp, which has a perforated steel band, the German-style hose clamp features a smooth inner band with a rolled edge. This design helps prevent damage to the hose during tightening, providing better sealing and durability.
What sizes of German-style hose clamps do you offer? Do you have options for 8mm or 12mm band widths?
What materials are typically used for German-style hose clamps?
Why is the automotive industry more inclined to use German-style hose clamps?
Does your factory support small to medium batch customization?
