Robinair R-134a Manifold Gauge Set A/c Rob40134a - Page 3 Questions & Answers
My robinair 347002k does not hold a vacuum.
Please check 1# Both service hoses (Red and Blue) fittings to the machine for damage of any "O" ring. 2# Check small compression fitting hoses back side of both gauges (Low and High) for any lose. 3# Check Vacuum check valve and Vacuum solenoid (see attach picture for location of Vacuum check valve and Vacuum solenoid) for any blockage or damage of check valve gasket and solenoid plunger. Hope this will help you to solve the problem.
