APPLICATION AREA

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.

 

VERSIONS

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 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 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.

 

SPECIAL VERSIONS

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.

 

MOUNTING INSTRUCTIONS

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).
