Tip to get Hose on bronze elbow

[SanDiegoChip]

We recently installed a new bronze through hull and valve and 90 deg elbow.
The 90 elbow is the problem.
The is set up to be used with our new macerator. We are using 1 ½ inch ID odor shield sanitation hose.
The problem is I cannot seem to get the hose more than an inch or so over the 90 deg bronze elbow.
The other problem is that this setup is not in an easily accessible place. I cannot seem to get good tourqe on the hose. Even still it should not be this hard. I was not happy with the first try so I cut the hose off (not easy) and tried again. I used soap and heated the hose. The hose even got a little distorted the second time from too much heat.
Question:
What if I took the 90 deg bronze elbow off and tried to find a plastic one?
Took it off and grinded it down. Not a safe solution I would think.
Any tricks to get the hose on better? It does work but I am not happy without two hose clamps on it. Now there is only room for one. This is below the water line.





Thanks,
Chip

I've had good luck using a heat gun, but it sounds like you have already tried that. Before using a heat gun I would submerge the end of the hose in a bowl of boiling water for a minute or two.

If it is really bad, you may have a metric barb or hose trying to get on to an SAE. Or a 2" hose trying to get onto a 2 1/4 barb or some equal there of.

A lot of the hardware items on my boat are metric being as it is french built, but hoses etc are in SAE, so makes for some "FUN" times (NOT) trying to get things to work. Altho from the pics, looks like everything is new! so this should not be an issue......then again.......

Otherwise, I like heat as you have tried.

The hose and elbow we purchased at Marine Exchange here in San Diego.
I will see what I can do to measure them at the store and see how they work together there.
Does putting the hose in boiling water make it too nimble to force onto the hose barb?
I have never tried it, worth doing. I have heard about that method but forgot it.

Warm the hose end in some VeRy hot water, then smear some peanut butter on the end of the barb. Tie a prussic with a grab loop onto the hose and brace the back of the fitting.

Hard and steady does the trick.

HOT water, close to boiling if you can, heat gun or hair dryer, then a torch or equal for heating up the hose, all work. Torches get touchy with the hose you have, down low and farther from the hose the better so the hose does not overheat and distort. I use torches for the heavy plastic wter hoses going into homes. I've also seen some take PVC glue on the end, and light a match, but this is frowned on by some jurisdictions........

have not used peanut butter, but have used other slippery items like oils to help slip things over barbs.

Best thing you can do is sit it in hot water and apply some soapy lube to the nipple. Using any greater heat source like a heat gun or torch will overheat the hose causing a molecular change in the characteristics of the hose. This can lead to premature failure.

FYI, the Odorless hose you are using is pretty lousy for head applications. You should be using Trident 101 which is recognized by many experts as the best hose for odor permeation.

I saw something on practical sailor or somewhere else talking about hose expanders. Obviously you need to worry about stretching the hose out too much.

After softening the hose in hot water, spray WD40 inside the end of the hose - works wonders.

+1 on the hot water and lube on the barbs.Good luck
