I have a Intex Hi-Output Air Pump, DoubleQuick II, model # 68614.
I could not find a size for a replacement O-ring (seal). But here is one that worked:
417 Buna-N O-Ring, 70A Durometer, Round, Black, 3-1/2" ID, 4" OD, 1/4" Width (Pack of 10)

. Pump works just like new now, and 10 for under $10.00!
