Description：
The 12mm hose clamp Germany type, complies with the DIN 3017 standard, featuring a worm-drive design for easier installation, enhanced strength, and superior sealing performance, making it widely applicable across multiple industries.
Material:
Multiple material options available.
W1 - All parts carbon steel with zinc plated. (screw, hosing and band)
W2 - Hosing and band stainless steel 201/301/304, screw carbon steel with zinc/nickel plated
W4 - All parts stainless steel 201/301/304. (screw, hosing and band)
W5 - All parts stainless steel 316. (screw, hosing and band)
Features:
Compared to 9mm hose clamps, the 12mm hose clamp increases the contact area by 33%, delivering more uniform radial pressure distribution. According to DIN 3017 standards, its burst resistance improves by approximately 40%. The wider sealing band effectively compensates for pipeline deviations and reduces preload loss caused by hose creep, making it particularly suitable for soft tubing materials with lower elastic modulus like EPDM and silicone rubber.
The screw head design ensures secure and foolproof clamp assembly with easy installation. Its shortened housing length provides even force distribution, preventing tilting during tightening.
The steel band features a smooth, lustrous surface with clearly stamped size markings, while its durable metallic finish maintains a like-new appearance throughout prolonged service.

Application:
The 12mm hose clamp is specifically designed for demanding industrial applications requiring enhanced sealing performance and mechanical strength. Its wider band profile makes it particularly suitable for:
- High Pressure Fluid Systems
- Hydraulic lines (20-30 bar working pressure)
- Elastic Hose Applications
- Vibration-Prone Environments
The increased contact surface provides 30-40% better vibration resistance compared to 9mm clamps, while maintaining stable clamping force under thermal cycling conditions (-40°C to +150°C service range). Its reinforced design meets ISO 9001 and DIN 3017 performance requirements for critical fluid containment applications.
Package: small bag/box + outer carton + pallet
