NORRES CLAMP 213
Bridge clamp with quick-release closure – for externally corrugated hoses
NORRES CLAMP 213 is a robust bridge clamp with quick-release closure designed for secure and nearly leak-proof connection of externally corrugated spiral hoses such as AIRDUC®, PROTAPE® and CP series. The special bridge geometry ensures uniform clamping across hose corrugations, while the quick-release closure allows easy installation and service replacement.
Properties and construction
- Practically leak-proof and highly secure clamping through special bridge design.
- Quick-release closure enables fast installation and convenient re-use during service.
- Manufactured from stainless steel (W2 quality) according to RoHS and REACH.
- Band: 1.4016 (AISI 430) · Clamp wire: 1.4310 (AISI 301) · Screw: 1.4301 (AISI 304) · Body: 1.4016 (AISI 430).
- Band width 9 mm.
Applications
For clamping externally corrugated spiral hoses in extraction, ventilation and conveying systems – especially suitable for AIRDUC®, PROTAPE® and CP hose series.
Technical note
In ATEX installations, continuous electrical contact between machine, coupling and hose is essential for proper equipotential bonding. Bridge clamps such as CLAMP 213 provide metal-to-metal contact across the hose corrugations and are therefore often the preferred choice with antistatic or electrically conductive hoses. Always select the clamping range according to the actual outer diameter of the hose or fitting.
Recommended accessories
- CONNECT 270–271 – stainless-steel couplings for process and food applications.

FAQ: NORRES CLAMP 213
What is NORRES CLAMP 213 used for?
For fastening externally corrugated spiral hoses. The quick-release mechanism makes it ideal for frequent assembly and service work.
How does CLAMP 213 differ from CLAMP 212?
Both use bridge geometry, but CLAMP 213 features a quick-release closure instead of a bolt, providing faster installation and disassembly during cleaning or inspection.
Can CLAMP 213 be used in ATEX areas?
Yes – when used together with antistatic or conductive hoses and proper equipotential bonding.
What materials is the clamp made of?
Band: 1.4016 (AISI 430) · Wire: 1.4310 (AISI 301) · Screw: 1.4301 (AISI 304) · Body: 1.4016 (AISI 430).
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.
