Also, instead of using the couplings, maybe you could try making a connector out of PE tubing that's one step smaller in diameter than the one you are using. Not sure it will work, but that's how my polypro is connected.

lower the length of the connector, I typically use a 3in. connector so it's 1.5 in. in on both sides.

 

*using another connector besides the grey connector will require extra work to keep the connector in place(rivets glue, drilling holes etc.), using grey connectors for pvc or pex tubing is the best.Hdpe and polypro are different plastic material so grey connector tind to not work.

What I have done is take my pipe cutters (which might have made them a little dull) and cut the gray connectors down, usually about 3 ridges.  Don't go to short however, especially if its a smaller hoop, because there won't be enough connector to get a good grip on the tubing, found this out with my minis! Give that a try and hope it helps!
