Push-in fittings as they are known from pneumatics in a full metal design with high-quality, oil-resistant NBR seals. It couldn’t be easier to connect lubrication devices such as drip oilers or metering oilers for chain lubrication with applicators such as lubrication brushes, lubrication brushes, chain lubrication pinions or lubrication rollers.

For TRO drip feed lubricators, the outer diameter Ø6 is to be preferred (-> a ventilated line through which only individual drops reach the lubrication point).
The DEK metering lubricator is preferably operated with lines with an outer diameter Ø4 (completely oil-filled line that does not empty itself due to the small diameter, even without a non-return valve in front of the lubricating brushes).
