If you are looking to an alternative to cutting tubing and pressing it over hose barbs with hose clamps, with the resultant difficulty in dissassembly, you might find the DuoTight System interesting. Based on double O ring sealed push in fittings, DuoTight allows easy repeated hose attachment and removal, as well as EVABarrier lined odorless tubing that costs no more than economy PCV tubing.
DuoTight features a patented dual O ring sealing system using high quality EPDM o-rings. The double o-ring means DuoTight have twice the sealing surface surface when compared with other push in fittings. This makes DuoTight even more reliable and reduces the chance of a leak. The double o-ring system also means that you can bend the hose with much tighter radius without causing leaking issues.
Clamps are not needed. To use the DuoTight System, simply cut your EVABarrier tubing to length (cut tubing square for best results, not at an angle), and push into the DuoTight fitting. To remove the tubing, simply press back on the sealing flange and pull the hose out. EVABarrier Hose and DuoTight fittings are rated up to 100 PSI.
This bulkhead fitting fits 8mm DuoTight outer diameter tubing. Fits into a 1/2" diameter hole and seals with an included O ring and stainless 1/4" BSP thread nut. This is the same part as Z87, except with a sealing back nut.

A: No, the thermowell bulkhead is slightly different, and the two are not interchangeable.
