The EZ Siphon Hose is 6 feet long, 1/2 inch wide and has a brass connector on one end with a ball inside to aid in suction. I have several of these and I like them. about a gallon per minute. When you get it, pull the hose and remove all kinks and never twist it very tight for storage and it will last a very long time. With the brass end valve you have to go up and down quickly. into a liquid such as water, gas, etc. to start the siphoning process. Thing works, I pump 50 gallons of gas in 50 minutes with this device. quickly! easy! great device!
