TheKamlok coupling, also known aslever arm coupling, is based on the US military standardMil A-A-59326Aand is standardised in Europe according toDIN EN 14420-7. These quick couplings allow for a fast and secure connection ofhose lines to pipe systems– particularly for the transport ofliquids and free-flowing materialssuch as granulates.
A special feature:M+Boffers a clever additional safety feature for the lever arms. This prevents accidental opening and reliably compensates for the system-related disadvantages of the lever mechanism.

Field of application
This quick coupling is used to connecthose lines to each otheror withpipeline systems– particularly for the transport ofliquids and free-flowing solids. Due to its origin from an American military standard, it is largelycompatible with Kamlok couplings from other manufacturers, even if they are not explicitly manufactured according to DIN EN 14420-7.
Thanks to thesimple and quick handlingit is preferred atloading and unloading pointsused, e.g. in industry, logistics or plant engineering.
Why M+B? – Advantages in detail
✔️ High-quality workmanship & stability
M+B couplings impress with precise manufacturing, robust material thicknesses and reinforced lever mechanics – for maximum lifespan and safety in daily use.
✔️ Optimised sealing technology
The design ensures that the seal is evenly loaded – this increases the sealing effect and minimises leakage risks.
✔️ Thoughtful variety of options
Available in many designs, e.g. with innovativelever safety, which prevents unintentional opening and can still beoperated with one hand– ideal for quick use under practical conditions.
✔️ Design against tipping forces
The fitting has been specifically reworked in the coupling area. This prevents the male part from wobbling, even when a connected hose exerts a tilting moment. Result: The seal sits evenly and seals reliably.
✔️ PFA-coated fittings available
For applications with high chemical requirements or elevated operating temperatures, M+B also offersPFA-coated versions– an ideal solution when flexibility and temperature resistance are required.
