This fitting is an equal tee and is made out of food grade plastic. They are commonly used to split gas lines in kegging setups.

Duotight fittings are designed to work by simply pushing in the compatible tubing.

Inside each fitting are dual EPDM o-rings that provide superior sealing capacity due to having twice the sealing surface area when compared to other push in fittings. This makes Duotight fittings even more reliable and significantly reduces the chance of a leak.

For optimal performance it is recommended that when cutting your tubing it is cut straight, not on an angle, this helps to ensure a complete seal.

Meant to be used with 5/16" OD (8mm) EVABarrier & Polyethylene Tubing.
