The optional bowl with a female thread allows an extension to be fitted quite simply. The one piece design also allows for inline applications. Leakage Oil Connection Seal or case drain lines can be connected to the filter through either of the clogging indicator ports providing that the leakage oil can accept a pressure of 3 bar / 43.5 PSI. It ensures that no unfiltered oil can return to the reservoir. Filter Bowl with Threaded Connection and Diffuser Diffusers mounted to the filter bowl minimise foaming and reduce noise of high Return-Line flows. For further details on STAUFF Diffusers please refer to the Catalogue No. 10 - Hydraulic Accessories. Attention: Connection pipe not included in scope of delivery!
