These couplings are specifically designed for use with EN ISO 14420-3 (DIN 2817) clamps. The hosetails have no serrations or ribs and therefore should not be used with any other clamping system.

The clamp and hosetail system is double locked, unlike other bolt or band clamps. It offers more security than all but the heaviest swage ferrules but offers the advantage of being able to repair or replace the hose.

EN ISO 14420-2-5 (DIN 2817) 'Safety' hosetails are made to suit metric hose. Customers should satisfy themselves that they are suitable for use with any imperial hose.

Use these couplings with our EN ISO 14420-3 (DIN 2817) 'Safety' Clamps.
