SS 300 Tubing Replacement

Tools/items needed

-Hot/Cold water
-3/8 inch clear PVC flexible hose tubing

There’s one thing that seems to be a certainty in life, at some point if you own an SS 300, something will happen which involves you needing to fix it.  Inevitably, a few months ago it was my 300’s turn to have something render it out of action until I fix it.  Thankfully it was an easy issue to fix; given the nature of what can happen to a 300 if not careful then things could be an awful lot worse so I should be quite thankful.  This problem was inevitable from the moment I opened it from new; the tubing on this example was kinked to the point of it showing a slight cut internally on both sides of the kink.  Efforts to use hot and cold water to smoothen it out can only last so long, and a few months ago the cut fully opened, meaning the tubing wasn’t sealed anymore and water spurts out when pumping.


Because of this I decided that because the original tubing was so annoyingly kinked there anyway, the best thing to do would be to replace it all together with some new better tubing.  First thing this involves is unscrewing the yellow tubing clamps on each end of the connections, to get to where the original tubing is sealed in.


Thankfully the tubing is weakly glued on, for the main connector to the blaster I pried it a little with a flathead screwdriver, but there really is no need as you can just bend it and wiggle it off with the force of your hands/arms, which I did on the other end.


It easily and quite cleanly comes off.



Now it is time to find some new tubing, I thought I would have to buy some spend ages finding the right size.  But no, turns out that the 3/8 inch clear PVC flexible hose tubing that I used on the previously done Hydro Cannon 2500 FF mod of mine was just right, and I had enough left.  It is really good tubing as well, and much stronger than the stock tubing and fitted over perfect.  I measured it against the old tubing and cut to length, I actually made it a bit shorter, the original tubing length was a bit long for me.


The it was time to get the kettle boiling and applying hot water to each end of the tubing to make fitting it over the connector pieces easy as shown.


Then with the tubing still hot I screwed the yellow clamps back on so they could mold in better, with that done I then just had to run cold water on it so it could stiffen up and seal nicely.


And with the process applied to both ends, repair complete!


The end result is more improved than before, stronger and more ideal in length and most importantly, not kinked to begin with like the stock tubing.  A quick test and it has all worked, no leaking on either end and pumping water through fine.
