Adjustable elbow connectors, DKO

Adjustable elbow connectors having a sealing cone plus O-ring join a cutting ring tube to a cone port following the DKO principle. The angular position is locked by a counter nut with a sealing washer, so the line can be aimed precisely. This group lists 91 items.

Tube as well as cone sizes run from 6 L (M12x1,5) up to 42 L (M52x2), plus 6 S (M14x1,5) up to 38 S (M52x2). Material choice covers zinc plated steel along with stainless steel 1.4571, complete or without nut plus ring for prepared tube ends.

How to choose Adjustable elbow connectors, DKO

What matters when choosing: properties, comparison and typical applications.

Technical data

⚡Sealing cone with O-ring - sealing towards the counterpart is elastomeric through an O-ring inside the 24 degree cone, rather than metal on metal.

⚡Tube 6 L to 42 L - light series up to 42 L (M52x2), heavy series from 6 S (M14x1,5) up to 38 S (M52x2).

⚡Cone end 6 L to 42 L - the cone diameter is stated per item, matching the tube size of the mating part.

⚡Adjustable angle - orientation stays free until the counter nut is set, so the tube needs no rebending.

⚡Materials - zinc plated steel or stainless steel 1.4571, the latter also offered without nut.

Applications

These connectors link tube lines to hoses as well as equipment whose port is built as a cone end, on hydraulic pumps, cylinders, control blocks. The elastomeric joint suits plants exposed to pressure surges or frequent dismantling, because the O-ring seals again at every refit. The elbow shape turns the line by 90 degrees directly at the device.
