If you own a boat or ever think you might own a boat, you are going to deal with stubborn boat hoses and connections at some point.
Using hose barbed fittings is an essential part of the equation and they come in several types. White nylon, gray PVC, and bronze are the main types and of course there are many other less common options.
The white nylon fittings are common, user friendly and the wimpiest of the choices. I only use them for the most light-duty plumbing chores. You have to be careful not to crush them with the clamps and I would never use them where it counts. The matching size hose does slide on them easily and that is the only real plus.
The gray PVC fittings are much sturdier and can be used to plumb most interior type plumbing, meaning don’t use them if their failure will sink you. The main negative to this type is that they are extremely tight to insert even into the matching hose size. This makes them a bear when you are in the normal awkward, hyper-extended position required by most boat projects.
Of course on a boat, you are usually trying to get leverage while hanging in a hole by your toes.
So the last type is the bronze fitting. They are the sturdiest of the three and of course the most expensive. I always used bronze fittings when plumbing hoses to the outside of the boat, or anywhere that failure is not a good option. Hoses do pretty well as far as sliding on and you will break the hose clamp before you hurt the bronze fitting.
So my quick tip is really for the grey PVC fittings.
Take a heat gun and warm the end of your hose. It should be just hot to the touch, but not beyond as the hose will loose enough rigidity to go on the fitting. A gentle warming and some spit should really help you get the hose over the grey fittings. Don’t forget some generous cussing cause it really does help. Of course when it cools, the hose is rigid again and most times you will need the heat again if you want to take the hose off.
Always double clamp where it counts and use the best stainless steel clamps you can find. Double clamp everywhere if there is room on the fittings.
