NORRES CLAMP 217
Bridge clamp with eyelet – for externally corrugated spiral hoses
NORRES CLAMP 217 is a solid bridge clamp with an integrated fixing eyelet, designed for secure and nearly leak-proof attachment of externally corrugated spiral hoses such as AIRDUC®, PROTAPE® and CP series. The eyelet allows the hose to be fixed to a wall, machine frame or mounting arm, providing extra stability and reducing strain on the hose and coupling.
Properties and construction
- Practically leak-proof and highly secure clamping thanks to the special bridge design.
- Integrated eyelet for fixing or hanging the hose securely.
- Easy installation and reusable design.
- Manufactured in stainless steel (W2 quality) according to RoHS and REACH.
- Band: 1.4016 (AISI 430) · Bridge: 1.4301 (AISI 304) · Screw and eyelet: galvanized steel · Body: 1.4016 (AISI 430).
- Band width 9 or 12 mm depending on size.
Applications
For clamping spiral hoses in extraction, ventilation, and conveying systems where the hose must be fixed securely to a static point. Especially suitable for AIRDUC®, PROTAPE®, and CP hose series.
Technical note
In ATEX installations, proper equipotential bonding requires electrical continuity between machine, coupling, and hose. CLAMP 217 provides metal-to-metal contact and enables permanent fixing of conductive or antistatic hoses. The eyelet can be used for grounding or for mechanical fastening to prevent vibration and tension on the coupling.
Recommended accessories
- CONNECT 270–271 – stainless-steel couplings for process and food applications.

FAQ: NORRES CLAMP 217
What is NORRES CLAMP 217 used for?
For fastening externally corrugated hoses where mechanical fixing or grounding is required through the integrated eyelet.
How does CLAMP 217 differ from CLAMP 212 and 213?
CLAMP 212 is the standard bridge clamp, CLAMP 213 includes a quick-release closure, and CLAMP 217 features a mounting eyelet for fixing or grounding.
Can CLAMP 217 be used in ATEX areas?
Yes – when used with antistatic or conductive hoses and proper equipotential bonding.
What materials is the clamp made of?
Band and body: 1.4016 (AISI 430) · Bridge: 1.4301 (AISI 304) · Screw and eyelet: galvanized steel.
How do I select the right size?
Determine the actual outer diameter of the hose and select a clamp whose clamping range covers this value.
