Flush-type grease nipples are particularly suitable for installations where extending or protruding nipples cannot be used.
In general, our flush-type grease nipples according to DIN are made of steel, zinc-plated and passivated, and they are featured with a cylindrical thread. Of course, our flush-type nipples are also available in different angle versions, with a self-forming thread, or as drive-in type. We offer various standard types also in brass or stainless steel V2A/V4A.
Upon request, UMETA manufactures flush-type grease nipples in further versions, with respect to e. g.
Flush-type nipples are only suitable for press-greasing by means of a UMETA extension tube or a UMETA push-type grease gun with pointed, pin-pointed, or combi-nozzle.

When maintaining your high quality machines and equipment, you should absolutely avoid quasi-lubrication!
What does quasi-lubrication mean?
Upon continuous operation, abrasion can easily take place between the metal piston and the metal cylinder of the grease gun. For this reason, the grease at the top of the piston can be pressed back into the cartridge at a low operating pressure without being noticed. In spite of all effort, no grease will be transported to the lubrication spot. In order not to expose your machines to this risk, we developed the UMETA TWIN-LOCK system.
In connection with two special sealing elements, it protects the precision piston from wear upon continuous operation. By the special arrangement of the sealing elements, the UMETA TWIN-LOCK system avoids quasi-lubrication and grease escaping the piston. The sealing elements are designed in a way that they adjust themselves to the corresponding operating pressure with respect to their sealing effect.
The EVER-FLOW system invented by UMETA ensures perfetct functioning of the UMETA TWIN-LOCK gun, even with thick grease and at the lowest temperatures.
This is ensured by an outlet valve equipped with a special ball stopper. Even semifluid biological grease will easily be transported by the vacuum developing during the pumping process.
This is another advantage of UMETA’s, where many other competitors’ products fail.
