1/2 in. I.D. x 5/8 in. O.D. x 10 ft. Clear Vinyl Tubing

The tubing does soften with heat from a heat gun. I have used it to get the tubing onto a hose barb, but, caution, it can get so soft that it doesn't have enough internal strength to be pushed onto the barb. I also can't tell how much strength is left in the tubing that has been heated when it is cooled back down. But, when heated it does get stretchy. Be careful not to overheat so it melts completely and watch out that when heated, touching the tubing can burn your fingers. I would recommend you experiment a bit with some extra tubing just to make sure it works for you.

I used it over a pex fitting when making a special hose pump setup for pumping fresh water into our trailer fresh water tank so I wouldn't have to lift the large jugs of water and get them into the filler neck. So far, after one year, it has worked very well. I connected a piece of the stiff PEX to a right angle fitting which goes into the water can and a piece of vinyl tubing to the other end of the fitting which then goes into the pump and then to the trailer. The pump doesn't generate a lot of pressure and everything is holding very well. Hope that makes sense.

I don't think the tubing is rated for this type of pressure. I would use the tubing and connectors designed for irrigation systems. You don't want it to come apart again and have to dig it up all over again.
