Yellow Jacket 93047 Ritchie Pump Drive Coupling

Buy this updated part from Yellow jacket. The original part (same part number) is a plastic/rubber sleeve that goes around the two shafts. Really poor design but nice to see Yellow Jacket step up and update the design and at a very reasonable price. If you have the sleeve type, replace it sooner rather than later. How do you know the sleeve type failed. It is the quietest electric motor and the pump is dead silent.

Fit like a glove on both shafts and turned a non-working Yellow Jacket vac pump into a working one. Cant beat perfection.

got the job done. What else is there to say?

This coupling saved me buying a new vacuum pump. Works great so far.

Fit my Yellow Jacket pump perfectly.

works great

Fit my older pump like a charm. Easy install. Much improved design over the plastic piece that was on it.

Fast shipping, exactly as described

it works

Thanks to OEM for upgrading this coupler as it works really well on my 15 year old vacuum pump
