Cap-Check is a portable, self contained hydraulic power unit with auxiliary equipment especially adapted to cleaning refrigeration capillary tubes. A 0-6000 PSI gauge shows pressure build-up if cap tube is restricted and also shows when chaser has passed through the tube.

A trigger operated gauge shutoff is provided so the gauge will not be damaged if pressures greater than 6000 PSI are desired. A 30 inch high pressure hydraulic hose with a 1/4 inch SAE male flare outlet connects the cap tube to the Cap-Check for simple handling. An adapter is supplied to connect the cap tube directly to the hose outlet without a flared fitting.
