ECOVOS Block Stop
Hose Connectors with Over-Assembly Protection
In practical use, leaks can occur in the sealing area of the assembled threaded hydraulic components. The reason for this is that the permitted tightening torque is often exceeded during the initial assembly or the scheduled replacement of hoses.
This results in permanent deformation of the metal sealing surface on the weaker component in the area of the sealing cone, increasing the risk of leaks during operation. The damaged components have to be replaced to ensure a permanently reliable connection.
VOSWINKEL is the first manufacturer of hose connectors to ultimately solve this problem: The new ECOVOS hose connectors with block stop feature clearly indicate when mounting is completed.
The essential difference to conventional hose connectors with 24° taper and o-ring is the predefined width of the gap between the two faces of the components to be joined.
This gap prevents excessive tightening torque, ensuring the required pre-tension for a reliable and permanently tight connection in the thread pairing.
The pre-tension created in the thread prevents the hose connectors from independently releasing under load. The full sealing function is permanently and reproducibly ensured even after several release and connect cycles.
When replacing a hose, the counterpart can usually be reused without problems.
Another great advantage is that the block stop works independently of the material pairing: The user does not have to adapt the torque, for example when pairing the hose connector with forged or turned connectors. This ensures additional leak protection, particularly in mobile hydraulics.
