slipping reinforced exhaust hose on fittings

[gary gerber]

Reinforced large diameter exhaust hose doesn't want to expand easily as we all know. I fell upon the idea of using an auto tail pipe expander to swell the hose. It works perfectly and no cursing is involved.

Once you expand the hose, release the expander and remove it quickly and slip the hose on the fittings.

In all seriousness, this method could also be used for installing sanitary hose for our heads. What an effort-saving idea!!!

Hot Water

I used some clear plastic reinforced hose on the high pressure side of my pool,, and when I replace it I heat the ends in some boiling water,, it then slides over the barbed ends real well.

Head and exhaust hose can be heated, carefully as to not over do it,
with a inexpensive heat gun available at home depot etc.

The large tailpipe expander 2-1/8'' to 3-1/4'' costs $13.99 at Harbor Freight. The medium one (1-1/2'' to 2-5/16'') is $11.99. The small one (1-1/8" - 1-3/4") costs $9.95. No electricity or flame required.

A heat gun at Home Depot runs from $59.95 to $169. One could buy all three sizes from Harbor Freight for less than one heat gun.

Checking account says: DING! Expander is more economical!!!

Like Jeff I use the boiling water technique which costs very little and is especially good on the high end sanitation hose.

The heat gun will be useful multiple times as hoses need to be replaced
throughout the boat, especially head hoses.

I've had luck using a hair dryer on high, something you probably already have laying around the house.

[ArtJ]

If you use a hair dryer, heat gun or torch (not recommended) be very
careful not to place in vicinity of gasoline or other flammables as you
may already know.

I agree with Baltimore sailor, that's why I suggested the tailpipe expander. In forty plus years of boating and having gone the "boiling water routine" the expander is easy, fast and inexpensive. My suggestion was published in DIY BOATING a few years ago.
