Key Applications

Automotive cooling systems

Radiator hose clamps that hold tight without cold‑flow leaks, even on plastic inlets.

Turbo & air intake piping

Boost‑ready worm clamps that manage heat cycles and vibration without backing off.

Transport machinery & heavy equipment

High clamp load and corrosion‑resistant stainless hose clamps for hydraulic, coolant, and air lines.

Industrial fluid handling & irrigation

Reliable hose pipe clamp sealing for pumps, filters, and drainage lines.

Mechanical sealing with tight space constraints

The short housing sleeve and slim band width let you fasten where universal screw clamps simply won’t fit.

Product Overview

A hose clip that bites evenly without chewing up the rubber. That’s what makes the German‑style eccentric design different from a run‑of‑the‑mill worm clamp. The asymmetric connection sleeve distributes tightening force all around the hose, so you get a firm, leak‑free seal without pinching or cutting the hose wall—even when you’re working blind in a tight engine bay.

Whether you call it a hose clamp, a hose clip, or a radiator clip, this DIN3017 German type hose clamp is built for jobs that demand high tensile strength and consistent clamping force. The short connection sleeve and the offset convex arc structure work together to stop the housing from tilting after torque is applied. The result? A flat, level fastening ring that stays put.

Performance Features

High tensile resistance

The steel band stands up to extreme pull forces and high destructive torque requirements, delivering dependable pressure resistance in boosted and high‑vibration environments.

Short sleeve, strong seal

The compact sleeve geometry concentrates clamping force where it matters, giving you optimal tightening force distribution and a tight hose connection seal.

Anti‑tilt arc structure

An asymmetric convex arc keeps the clamp shell from shifting or cocking after you torque the screw. The clamping force stays level around the full circumference, preventing uneven bite marks and weak spots.

Frequently Asked Questions

What are the main applications for these German-style hose clamps?

They are highly recommended for automotive cooling systems (radiator hoses), turbo and air intake piping, transport machinery, heavy equipment, industrial fluid handling, irrigation systems, and installations with tight space constraints.

What materials are available for the hoop, shell, and screw?

We offer three main material configurations: W2 (SS430/SS300 band & shell, galvanized iron screw), W3 (full SS430 stainless steel), and W4 (full SS300 stainless steel). SS304/SS430 combinations are standard for most sizes.

How does the eccentric design prevent hose damage?

The asymmetric connection sleeve and offset convex arc structure distribute the tightening force evenly around the hose circumference. This prevents the housing from tilting during torque application and avoids pinching or cutting the hose.

What is the recommended installation torque for these clamps?

For both 9mm and 12mm band widths, the recommended installation torque is 3-4 NM, with a minimum destructive torque of 6-8 NM.

Why is the short sleeve design beneficial for tight spaces?

The compact sleeve geometry minimizes the overall profile of the clamp shell. This permits uniform radial load distribution even in extremely confined engine bays or mechanical compartments where standard clamps cannot fit.

Are these clamps compliant with industrial standards?

Yes, these German-style hose clamps are designed and manufactured in compliance with the DIN3017 standard, ensuring high tensile resistance and high-performance sealing integrity.
