I have two 27mm, 3.5m hoses that I want to join together. I'm looking for a fitting that will join the two without causing a stiff, inflexible portion in the hose length or as little as possible. I know I could change hose end fittings, then put a barrel-type fitting in between, however that causes that longer-than-desired straight portion and I don't want that. Is there such a fitting?
