This BOWEX M-65 coupling insert is the flexible sleeve that connects the motor to your Busch vacuum pump. Made of durable polyamide material, it acts like a shock absorber for your pump’s drive system. It fits perfectly on Busch RA 0400 C, RA 0502 C, RA 0630 C, and RA 0760 A PLUS series pumps . If your vacuum pump feels shaky or makes clunking noises, this part is likely what you need to replace.
