Review on 🚀 Ritchie Pump Drive Coupling for Yellow Jacket 93047 by John Thawngzauk

Yellow Jacket is a good product BUT a vacuum pump repair will normally require both parts shown. Unfortunately what comes is a one piece so I returned it and used a less expensive one piece plastic bushing that fits either end of the drive. I would have preferred Yellow Jacket's metal cases, but the plastic cases last a few years.
