5.1.6.8Front Panel Tubing Plate Quick Disconnect (QDC) O-Ring Replacement

The front panel quick disconnect (QDC) blocks (if your 98RK-1 Scanner Interface Rack is equipped with front-mounted tubing) are individually removed. If a leak is suspected in the front panel quick disconnect (QDC) block:

(1)Remove the six (6) 4-40 x 3/8" anodized Allen-head screws from the face plate of the front QDC, and remove the QDC panel.

(2)Inspect the front QDC O-rings and if any are suspect, carefully remove with tweezers. (Do not scratch the QDC block, as this may induce additional leaks.)

(3)Clean the O-ring cup with a lint-free applicator moistened with a cleaning fluid such as acetone, alcohol, Freon, or any other substance that evaporates quickly and leaves very little residue. Remove any excess cleaner with supply air (dry) as soon as possible. Do not blow air directly into the holes of the surface since that could drive the fluid into the scanner.

(4)With clean hands, apply a small amount of Krytox® fluorinated grease to the palm of one hand and rub it out evenly with your index finger. Place one of the new (red) O-rings onto your greased palm. Work the O-ring around until it is evenly greased. There should be no white area of excess grease on the O-ring. Make sure there is only a thin film of lubrication on the O-ring. Using your greased finger, roll the greased O-ring over the flared portion of the tubing connector and into the O-ring cup. Ensure that no grease enters the hole that leads into a transducer.

(5)Apply a very small amount of Krytox® fluorinated grease to the entire manifold, being careful not to allow any excess grease to cover any tubing port.

(6)Re-install the QDC assembly. Use the aligning pin in the QDC panel to ensure that proper pin alignment.

(7)Test your scanner to ensure proper operation.
