SANLI Grease Nipple 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 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.
