Pushrod Tube Seal Kit for Continental Engines GTSIO, LTSIO, TSIO-520; IO, IOF, TSIO, TSIOF-550   Real Gasket Tennessee has received FAA-PMA approval for improved design on the pushrod tube seals for Continental engines. These seals are designed to give 37% more sealing area at the point of contact with the pushrod tube.  The beveled top of the seal and companion crown washer will allow more spring pressure to the tube therefore ensuring a tighter seal.
