Can you run plutonium through this hose to fill a spaceship? Asking for a friend.

In the first answer, Sid V is confusing Plutonium with Uranium. With Plutonium the fuel/weapons/reactor grade isotope is Plutonium 240. With Uranium it is 235. With Plutonium 240 the Flexzilla hose should work just fine

Have you tried rolling this on a hose reel? Does this make a difference with it's supposedly non-kinkyiness?

This hose goes onto all my reels perfectly 75-100’. We usually roll onto the reel with the hose pressurized as it works and looks great. We love these hoses

How much does the 100' hose weigh? One description lists an item weight of 7 pounds and a shipping weight of 15.3 pounds.

100' is 16 pounds, 75' is 12 pounds and 50' is 9 pounds. Definitely about the lightest weight hose you can find. Gatorhide is a very similar hose with similar weights. They feel deceptively light weight. The great thing about these hoses is they almost absolutely never kink when they are under full water pressure. Well, they do, but because of the rubbery construction the water pressure pops the kink out by itself in about 1/4 second or so. You wouldn't even know the hose kinked if you blinked. I have a business soft washing dirty roofs, houses and building exteriors and my employees and I absolutely love this hose.

What is the burst/psi strength?

At http://www.flexzilla.com/water/garden-hose/ , Flexzilla states, "Max. working pressure at 70°F: 150 psi." If the pressure at your hose cock exceeds 150 psi, this is not the hose for you. Furthermore, the maximum working pressure rating will drop off quickly as the hose temperature rises.
