Main Seal
The main O-ring seal should be replaced at least every 1000 cycles. FasTest recommends a daily visual
inspection of the sealing O-ring, located at the tip of the lling nozzle. Inspect for tears or cracks in the
O-ring surface. Replace O-ring if tears or cracks are visible or veried. Some applications require more
frequent seal changes.
