The tesla valve is just amazing. Like a standard valve, it only allows fluids to flow in a single direction (in but no out). However the tesla value is one single entity without any moving parts.

(Other valves may use things such as flaps to achieve similar results.)

Since it doesn't have any moving parts, you'll never to worry about the valve being worn down.

(or at the very least, it'll take way longer to wear down)
