You can find most any brand coupler available here. Most couplers provide a swivel action which is said to be less stressful on the wrist and forearms. Also, be sure to purchase o-ring kits for any used swivel couplers you purchase. This will ensure you get a good snug fit with maximum efficiency, and minimum air and water loss. If the coupler you are looking for is not available here, you might consider posting in Handpiece Forum to see if anyone has the one you are looking for.
