TWL: Hose and fittings
I am looking for help sourcing some hose and fittings for my holding tank.
Like replacement for the existing 21 year old hose is what I would like to
find.
The hose is double wall black rubber. Wall thickness is all of 1/4 inch and
likely more. It is made of two layers bonded by a fabric layer. There is no
reinforcement wire. The fittings are preformed elbows with insets of two
brass hose barbs. The hose barbs can be removed with a little effort,
leaving a detent of the thickness of the inside hose layer for a length of
about 1 1/4 inch. This means that the hose barb can be placed on the hose
and the elbow then set on the rubber collar bonded to the barb. It also
readily adapts to modern ABS hose barbs with a vary good seal.
As I have come to work with this stuff vs. the modern plastic, it is amazing
how neat and easy stuff goes together. But mainly this hose has remained
odor impermeable over 21 years while the white plastic holding tank hose is
such a bitch to work with, leaks at the joints, and worst is permeable to
odor.
I have found a replacement hose from Trident but it is reinforced with wire
so it can't be used as well with these fittings.
Would like to find the original manufacturer.

I have had good luck with Amazon Hose & Fittings, dowtown Miami. They are
listed and have a decent catalog.
They have a strong commercial Marine customer base and the help is usually
on the ball.

Don't know about 21 years, but 3 years ago I bought some "odour
impermeable" hose from my local marine store. It was a bit tough to
get it over the barbs until I started softening it with an electric
space heater. There are two types of septic hose, one is quite
thin-walled with a wire reinforcement and relatively inexpensive
(that's what was in the boat and it reaked). The other, also white is
heavy walled and sinfully expensive. This is the type I'm using and
sofar - no odour, no leaks and I am a liveaboard.
There was an extensive comparison on this subject in Practical Sailor
a few months ago. You might find that interesting reading.

Just finished a new installation and used the Extra Heavy Duty Hose
listed in the Boat/US Catalog. As George pointed out very expensive and
you need a source of heat to but the fitting on with. This far no sign
of odor.

I'm replacing the holding tank in my 34 MT. It's under the fwd. cabin
sole and is a major pain to get to as well as too small - 9 gal. for a boat
with 2 heads is incredibly weenie.
It is a long run from the aft cabin head to the holding tank forward. I'm
planning on using schedule 40 PVC pipe for the long straight run and use the
heavy wall sanitation hose on each end for strain relief.
OK, I'm bracing myself. Who's gonna tell me what a bad idea this is?
Seriously, I'm open to suggestions, I don't want to put all the effort in to
have a problem.
