STAUFF FI-ELD-10S-B-W3-DKO-MS

DKO cutting ring connections are a common metric fitting standard used across European-style and industrial fluid power systems, so if your setup is already running metric tube fittings in that format, this indicator should line up without needing adapters. The FI-ELD-10S-B-W3-DKO-MS is built around that connection type, and the size 10 designation tells you where it sits in the filtration circuit sizing range. If your existing hardware uses DKO ports, you're in the right ballpark.

In a hydraulic filtration circuit, this part serves as a filtration indicator component used for contamination monitoring, so it fits the role of showing when the filter condition needs attention.
