【Widely Applicable】JDIAG gas can vent caps kit fit any 3 gal/5 gal non-vented plastic fuel/gas cans, provides vents and allows for quick and smooth flow of gas.
【High Quality】JDIAG gas tank vent caps are made of "High Density Polyethylene"(HDPE) plastic, which is fastened and durable. Do not need a pair of pliers to open when the gas can is vacuumed and do not pop when the can is pressurized either.
【Easy to Install】 You need to drill a 31/64" or 15/32" hole(which is slightly smaller than 1/2") into the can, or used a step drill bit with a 18 normal drill bit as a pilot drill and drilled the step bit to one half inch hole. Put soapy water on the vent and tapped the gas can cap replacement into the hole with a small mallet. (Be careful not to get debris inside your gas can)
【Easy to Operate】If the hole of the gas tank vent cap is drilled a little bigger, it is recommended to use a touch of sealant/silicon or fuel grade epoxy to the outer rim of the vent cap insert, it needs to be securely fastened to the gas tank to provide a good leak-proof seal.
【Warranty Service】Use the vent cap insert to retrofit these inconvenient gas cans in order for them to function properly and no more spill gas on your mower. 12 months warranty provided.
