Luer Fittings

Above are an assortment of Luer connection devices. At the top are hoses, you can see various T and Y connectors. Devices that connect a hose to a fitting are know as "Barbs". The device at right is a Luer Barb because one end is a Luer connection and the other is a barb spigot that a hose slides over, it stays in place with a sharp edge on that barbed collar. Luer devices come in male and female.

Above Left is a Male Luer connector that is pointed at and will connect to the Female Luer Barb above right wih a half twist. Just the opposite of a garden hose, the part you turn to tighten is the male because it posseses the insert element into the protruding female element.

Do you need to know any of this? Not unless you want to make your life easier with standard connectors that will save you ink spills, allow you use your equipment more efficiently and pay less for the funny little connector gizmos that some companies will charge you $5 each for. You can buy a bag of these things for a few bucks.

Below is a Female Luer Barb on a syringe being used to fill a "Dog House" Pitney Bowes 769 with phosphorescent ink. Well, not really, there is no ink in the syringe. But you get the idea. You can buy a 769 compatible for $4-5 or you can refill one in 30 seconds for pennies. Your customer pays you $24.99 or buys one at Staples for $39.99. The 1/16 or 3/32 Luer fitting is 15 cents. Call if you need a manual that tells how to do it.
