J/B Industries PR-308 Flexible Vacuum Pump Coupler Sleeve Only

It was perfect fit for my jb platinum vacuum pump.

Perfect match

Fit my DV-142N perfect and got me up and running.

Quick delivery worked perfect

Used this on a JSB 3cfm vacuum pump. Works like a charm. Material seems to be tough enough to hold up under normal conditions.

I chose the part for my pump per suppliers information. Easy to replace and worked perfectly.

Cumple con su propósito, mi esposo logró reparar su bomba de vacío con esta pieza

This part broke and my generator and was more readily available than the Kohler part so I took the gamble and fit perfectly. Considering the application of both pieces I expect it to have the same longevity and will definitely order another for backup.

Easy to install , just remove 4 long bolts on back of motor , put the new one on the shaft , line up the splines and re install the motor. I guess the replacement green one will have a longer life expectancy or work better than the black one.
