I'm replacing two cockpit
drain seacocks with new bronze Groco seacocks. The hose barb adapter for the Groco seacock takes 2 1/4" ID hose. The cockpit
drain tube on the other end takes 2 3/8" hose.
So the question is how to go from 2 1/4" on one end to 2 3/8" on the other end.
Would it be possible with a heat gun and some lubricant to get a 2 1/4" ID hose onto a 2 3/8" OD tube (a difference in diameter of 1/8"). I've never tried it and don't have any 2 1/4" hose on hand to test with so I thought I'd turn the collective wisdom of cruisers forum!
Unfortunately I can't find any adapters for the seacock to make it take 2 3/8" hose (which would be the ideal solution).
