Okay what size brass goes over petg and 9/16 or 17/32 can fit into?
You would need at least 3/4" brass depending on the exact measurements of your petg. Though in that size I assume it would be outragesouly expensive.
Time for some math. 17/32" fits inside 9/16" or 18/32". 1/2" fits inside 17/32". I assume your trying to make some sort of breech? 9/16" fits into 1/2" pvc.
Correct me if I'm wrong on anything thing.

If you're talking about thickwall/medium PETG (.572" OD), good luck finding something to nest over it. 3/4" brass is way too large (.692" ID). 5/8" brass is .597" ID, and 19/32" brass is .566" ID.You would need at least 3/4" brass depending on the exact measurements of your petg. Though in that size I assume it would be outragesouly expensive.

9/16" (.5265" OD) brass fits in 1/2" PVC (~.608 ID, varies greatly), but not very well, and won't seal on it's own if you're trying to make this air tight.

-Stick a 1/2"PVC sheath into a coupler, mark the exposed PVC
-Cut the loading port 1/2" offset from the mark
-Take a 1" stub of 17/32" brass and put a couple tightening rings on it
-Remove the PVC from the coupler
-E-taped and goop it to the back of a PVC sheath
-Take your desired length of PETG and stuff it into the other end of the sheath
-The brass should make a decent seal(mine is airtight)
-There should be some exposed PETG. If not, remove the PETG and cut the sheath down
-Goop another piece of PVC onto the exposed PETG. Pull on this to open the breech
Ta-Da! Cheap but effective breech. The nice thing about medium-walled PETG is it's elasticity, which this breech employs. DeadDumpter did a similar writeup on Canadian Nerfers a long time ago.
