## Discrepancy

STATIC CONDENSATION BULB P/N S-1258-1 FOUND SEPARATED FROM AN 1/8 PIPE BY PIPE 90 DEGREE FITTING. THESE CONDENSATION BULBS ARE OF VERY CHEAP PLASTIC AND ARE FAMOUS FOR LEAKING RIGHT OUT OF THE BOX. THERE SEEMS TO BE NO OTHER PART OF BETTER QUALITY. I HAVE SEEN THESE PARTS CAUSE THE 91-411 TEST TO FAIL MANY TIMES. AIRCRAFT SPRUCE SELLS THEM AND THEY WILL AUTOMATICALLY SEND ANOTHER IF THE NEW PART FAILS BECAUSE THEY KNOW THE PROBLEM. LOCAL REPAIR STATION SAID WE NEEDED TWO IN A 182 SO WE ORDERED FOUR-YUP TWO WERE BAD RIGHT OUT OF THE BOX. PLASTIC CRACKS EASILY WITH EVEN MILD TORQUE IN INSERTION IN THE AN FITTING.
