783. Do I need compression nuts for air tubings to connect onto air switches?

Compression nuts for air tubing are not available and are not required for air switches and air buttons that we sell individually. Compression nuts are also not required on SpaGuts brand Peumatic spa controllers with air switches and provided air buttons. New style air switches and air buttons have nipple fittings that allows air tubing to stay on firmly and tight without a compression nut being installed. Just make sure to insert the 1/8 inch or 1/16 inch tubing, by hand, all the way in as much as possible into the center nipple fitting of the air switch or air button.
