That tubing looks a lot like the stuff I bought. I think the brand was Beckett? I've worked with various kinds of tubing my entire working life. That stuff is expensive, and it's cr*p. It punctures very easily between the ribs, tears when you try to remove it, and it's an odd-duck I.D. that doesn't fit correctly on the barbed fittings that are available at the local hardware stores. I never woulda bought any of it if I'd known how many failures it would cause.
Next time I'll get the real ribbed PVC pipe, or something - anything - that's more durable than that junk.
