Germany Type Hose Clamp
The Germany Type Hose Clamp is a versatile and essential component used in various industries and applications. This clamp is specifically designed to secure hoses, pipes, and tubing to fittings and adapters, ensuring a leak-free and secure connection.
Germany Type Hose Clamp Supplier from China
The Germany Type Hose Clamp — also known as the German style worm-drive clamp or DIN 3017 clamp — is the most widely used hose fastening solution for securing rubber, PVC, silicone and composite hoses onto fittings, nipples and barbs.
Its perforated band and enclosed housing design deliver high clamping force with low tightening torque, giving a uniform 360° seal that resists vibration and pressure pulsation better than open-ended clamps.

Key Features
- Perforated band with rolled, deburred edges prevents cutting into soft hose walls.
- Enclosed housing keeps the screw aligned and concentrates clamping force evenly around the full circumference.
- Low free-torque design means faster assembly on the production line and less operator fatigue.
- Available in W1/W2/W4/W5 material grades to match corrosion requirements from indoor plumbing to marine use.
- Wide size coverage from 8 mm to 220 mm covers nearly every industrial, automotive and agricultural hose.
- Reusable — can be loosened and retightened repeatedly without losing clamping force.
Application Scenarios
- Automotive & truck: coolant hoses, turbo and charge-air hoses, fuel lines and radiator connections.

Frequently Asked Questions
What is the difference between W1, W2, W4 and W5 grades?
W1 is fully galvanized carbon steel for general indoor use; W2 has a stainless band with a plated screw; W4 is fully stainless 304 for outdoor and mildly corrosive service; W5 is stainless 316 for marine and chemically aggressive environments.
Can I get a mixed-size carton for distributor stock?
Yes. We can pack assorted sizes into a single display carton or a labelled assortment box, which is popular with hardware and irrigation distributors.
Do you supply clamps with custom logo or part number?
We can laser-engrave or stamp your logo and part number on the housing, and print custom barcodes or private-label cards on the packaging.
What is the lead time for a 20ft container order?
Standard stock sizes typically ship in 7–15 days; mixed or fully customized orders usually require 20–30 days depending on plating and material grade.
