Featuring a single shut-off valve activated by a metal button, it allows for fast and easy fuel flow control and quick disconnection of carburetors or fuel tanks. Ideal for professionals seeking efficient maintenance tools, it comes with a 1-year warranty but is not pressure-resistant. ## Description Features:1. Quick disconnect coupling for 6mm (1/4 inch) inner-diameter fuel hose. Splits the fuel line in seconds so you can lift the tank or remove the carburetor without draining fuel.2. Single shut-off valve: the valved half closes the tank side automatically when the coupling is separated. The other half has no valve, so a few drops may come out of that hose. Keep a rag handy.3. Press the metal button to release. Push the halves together until they click. Can also be used as an inline fuel switch.4. Nylon body, rubber O-ring seal, metal release button. Made in Taiwan.Check before you order:For gravity-fed carbureted engines only: motorcycles, scooters, ATVs, dirt bikes, generators, lawn mowers and other small engines. Not for fuel injection (EFI) or any pressurized fuel line; this is a non pressure-resistant coupling.Measure your hose inner diameter. 6mm / 1/4 inch = this listing. 8mm / 5/16 inch = KiWAV 8mm coupling.Installation tips:Push the hose fully over the barb and secure with a hose clamp on each side. Before the first ride, connect the halves, tug to confirm the latch, then check for leaks with the fuel tap open.
