<p class=MsoNormal><span style='color:#1F497D'>No, they do not look like your
Genovas. I don’t have a source for a picture, so I cannot direct you.
But they have the barbed ends that you commonly see on PVC items (and, as I
said earlier, they are exactly what Jude Reveley is using with good success
with Nitrile hose. I did stop by Lowes and bought a piece with a 1 ¼”
barb to just try with the hose. It was too loose in the 1 ½” hose for me
to want to try it, plus I spent over a hundred dollars on these end fittings and
spent a lot of time putting them together so that they do not leak (they don’t,
but the crapola Home Depot hose I started with sure did!) So I am invested in
making these items work, plus the Nitrile hose was $168.00 for 50 feet of it. <o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>An update on my efforts today:
I stopped by an auto parts store and bought a pipe expander (used to expand an
end of an auto exhaust pipe to fit over another pipe. It will expand from 1 ½ to
2 7/8”. <o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>I was able to insert it part way
into the end of tubing that I worked so hard on yesterday. When you turn it,
it expands the cylinder, which in turn expands the pipe. It does work, but I
found that it is just slightly too big for my task. The net result was that,
because I was not able to insert it far enough into the hose, it expanded the
hose at the end with a bit too much taper, so the barb would get started, but
go only so far. It’s just barely the wrong size, but it worked well enough
to tell me that the proper sized one should work. <b><i>Grainger</i></b> sells
what looks like what I need:<o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>This is made by Westward, with a
range of 1 1/8 to 1 ¾”. It sells for $21.43 as item no. 1MUE3. The
smaller size should allow me to fully insert the expandable portion fully into
the hose. As I tighten it, it will do so for as much of the length of the hose
as I will need to fit the barb, and with very little taper. I already know
from the size that I have that it will permanently expand it, so I believe this
will work. <o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>It should work pretty quickly
too. I have a pneumatic screw gun, and put the proper size socket over the end
(the part you see on the right), and was able to expand and contract it quite
quickly. So I believe that, once I get it set up, I should be able to do what I
need to do quickly, and in a controlled fashion. <o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>I’ll give a further report
to all who are interested once I secure the proper size pipe expander. By the
way, the 1 ½” size I have now would work well with those who prefer 2”
hose. <o:p></o:p></span></p>

(the old fashioned gray stuff) and get the cap started in the hose. Through a

will insert all the way.<o:p></o:p></span></h1>

the cap inserted about half way, the hammering technique involves (assuming

partially inserted cap thread area and tapping. Strange as this sounds it will
work. Use hose/band clamps to tightly secure.<o:p></o:p></span></h1>

your using the 1.25” stuff for the end caps. I’ll head over
to Lowe’s tomorrow morning and buy one or two barbs of that size and see
if that is going to be a workable solution in a test fitting. If that
seems to be the ticket, then I can go about securing some ones of sufficient
quality. <o:p></o:p></span></p>

hose to twist and hammer – by hand? I was finding that the hose
wanted to fold over against the pressure of the barb against it instead of
staying straight on. I have some large channel lock pliers, so I will try
that too.<o:p></o:p></span></p>
