These are the replacement fittings that thread into the base of your AirDog product. All fitting options have descriptions of what model AirDog products they fit. Please align your model number and thread type to the option set below to determine what fittings you need! There is one clear way to tell whether a fitting is ORB (O-Ring) or NPT (Pipe Thread). If your current fitting is threaded into the base and is tight, if you can still see the threads on the fitting, it is an NPT fitting. ORB Fittings have an O-Ring at the base of the fitting that seals them, and no threads show when they are tight! If no model number is present on your pump, you can call our technicians to verify fitment!
