I can't even imagine.... Normally I would say, so that the customer has problems finding DIY parts so they would have to go back to DangerDen for some repeat business... However, seeing that Danger Den's R&D VP still hasn't found the right fittings I don't see that being the case this time. Maybe they got a good deal on a bulk order of 9/16th-18 threaded hose barbs... who knows.qdemn7 said:So whay did DD use such an oddball thread?
