Hi, kindly post a picture. Maybe we can figure something out. And yes, the nonstandard fitting and hose sizes are a very expensive pain in the wallet. Nothing matches anything. You have to buy oversize and use duct tape and other methods to fit different brands together. I finally gave up and stick with Rockler stuff. They seem to understand that the OD of a connector needs to be ever so slightly smaller the the ID of a hose. I have a box of parts that fit nothing. Makes a fella wanna shout Ratzanfouterdrizzlehump!

I have a big box of nonstandard, supposedly same size, fittings. What works best is sticking with one brand for the most part, but using schedule 20 pipe and aluminum duct tape to seal the leaks. I have done my best to avoid T connections since the dramatically reduce air flow. I go with Y connections or two 45s to ease the change in direction.
