This is the full service kit for MSR MiniWorks and WaterWorks microfilters, the parts that keep an older pump filter working like it did on its first trip. It covers the wear items that fail after seasons of pumping silty Cascade creeks: the O-rings, valves, inlet filter and washer, plus silicone lubricant and instructions. Worth keeping one in the gear closet so a tired seal never ends a backpacking trip.
