The green stripe is 101 sanitary hose. It will be good for odor permeation
for several years. The white may be of three different types. 148 is a
medium wall sanitation and general purpose hose that is subject to
permeation rather quickly. 144 is slightly heavier walled with a hard vinyl
spiral and will last a little longer. The third is AVS96 manufactured by
AGS in Australia that SeaLand was once the exclusive dealer for. It ain't
cheap but it is as good or better than 101. Actually resists odor
permeation better than all of them.

Here is a message that appeared recently on the CS mailing list about hose
replacement. I'm interested in your comments.

What is the black hose with green stripes that he referred to?

I have a lot of experience with this. In my CS 30 I replace the hose I
think you're
talking about with that white Head hose that is supposed to be the best
hose for that job.
It was brutal to work with and had to be heated to get it to fit over the
fittings it was
supposed to attach to. After hours and hours of just absolute brutal work
I finished it.
Within two months you could smell the head smells. Later I learned that
hose will not work
anywhere that water sits in the hose. The oder will come right through.

Next boat next attempt. I used that black rubber hose with the green
stripe on the outside
and reinforced with wire. It is just as brutal to work with and extreemly
expensive but, no
smell after 2 years!!!!!!!!
