- with tapered thread

With the Umeta SafeLube-system

you are always on the safe side due to:

  • special designed springs
  • specific interior geometry
  • high-quality balls
  • inhouse case hardening according to DIN

make our grease nipples

  • extremely leakproof and you avoid unnecessary loss of grease
  • durably and wear-resistant
  • permeable, even under high pressure

. . . and therefore simply a good choice!



UMETA Hydraulic-Type Grease Nipples according to DIN 71412


UMETA hydraulic-type nipples are suitable for all standard lubrication points, which have to be frequently lubricated in a reliably way. Due to their multi-purpose field of application, they are the most commonly used types of grease nipples.



In general, our hydraulic-type grease nipples according to DIN are made of steel, case-hardened, zinc-plated and passivated, and they are featured with a tapered thread. The head diameter is 6.5 (-0.2) mm /0.256" - 0.008". For safety reasons and in order to avoid abrasion wear, the standard demands 550 HV (Vickers) as a minimum for a surface hardness. Therefore, we operate this decisive process in our own curing oven. We offer various standard types also in brass or stainless steel SST303 + SST316L (V2A/V4A). Of course, our hydraulic-type nipples are also available in different angle versions, with a self-forming thread, or as drive-in type.



Upon request, UMETA manufactures hydraulic-type nipples in other versions, with respect to e. g.

  • dimension
  • material
  • thread size
  • thread form (e. g. with cylindrical thread)
  • different opening pressure
  • surface colour (e. g. yellow passivated)
  • further surface treatment
  • unhardened
  • etc.



In order to allow for a proper lubrication with all common grease guns, the head space, which is necessary for installation, should be considered (please see table with dimensions).
