Hose Baffle Seal - Zero Degree (Straight Thru), for AE466-6 hose (the brown one). 
 
Lycoming, Continental, and others
 
A part to pass a hose through the engine cooling air baffle.  Uses #8 washer head screws (included).  Max temperature = 300 Fahrenheit.   A drill jig is included for ease of assembly.
 
A drill jig is recommended for drilling the holes to mount the seal because the split line holes have a line fit.  Using the seal as a drill jig may oversize the holes and reduce the tight clearance fit.  A free drill jig will be included in order to complete the installation for the engine.   
 
Note: These are priced and sold per assembly.  Each assembly contains 2 pieces.  The item will ship exactly as pictured.
