Review on 🔧 6 Pack of Gas Can Spout Gaskets - Replacement Rubber Rings for Fuel Washer Seals and Spout Gasket Sealing Rings - Compatible with Most Gas Can Spouts by Trey Angus

If you mean FR1G501, you can! Your jar comes with a round o-ring that fits into a groove on the dispenser. These are thicker flat o-rings with an internal groove. The lower bottom edge of this o-ring fits into the groove that holds the original o-ring. The o-ring groove fits over the top wall of the dispenser o-ring groove and the top wall of the new o-ring now covers the top surface of the dispenser. When you screw the dispenser back onto the can, you may feel the resistance of the new o-ring long before the old o-ring, and the new thickness gives you the confidence that you can tighten it to its limit. A quick reverse test of my 4 canisters showed that not a drop of fuel escaped 👍🏻👍🏻👍🏻
