Yellow Jacket 93047 Ritchie Pump Drive Coupling

Great price

Fit perfectly, got my Yellow Jacket Evac pump running again. Much better coupler design!

Fit perfect

works great

Perfect fit. Better design than original.

The quality and value.

Pump came with a metal and plastic coupling. The plastic got brittle with age and broke. This coupling is one heavy duty metal assembly which is easy to install and will never break. Highly recommend this product!

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

I just installed this 93047 coupling on my older YJ 6-CFM pump and it is now up and running again. The old coupling was original to the pump and had a splined plastic tube setup, similar to what JB uses on their pumps, but a little longer. This new YJ coupling design uses a rubber spider in between the metal halves instead of the plastic tube and fit my pump perfectly.

Solved my problem.
