An especially strong and reliable connection with the grease nipple will be achieved by using the bayonet coupler. The construction design also results in a specific high flow-rate of grease. Particularly suitable for the heavy industry, for example ship building.
In general, our bayonet nipples are made of steel, zinc-plated and passivated, and they are featured with a tapered thread. We offer various standard types also in brass or stainless steel V2A/V4A.
Upon request, UMETA manufactures bayonet grease nipples in further versions, with respect to e. g.
As suitable lubricating nozzle, we recommend our bayonet coupler.

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.
