UNDERSTANDING AIRLINE

Airline Fittings (Hose Tail Fittings) are commonly used for many applications. When deciding on what fitting to use it is important to understand the following.

Hose is measured by the internal diameter (ID) and can be connected with all Hose Tail Fittings. The most common types of industrial hoses are CVT (Clear Vinyl Tube), PVC (Braided Poly Vinyl Chloride) and various forms of rubber hose. Note That CVT is actually a hose and not a tube.
Self Store Hose is measured by the ID. (1/4" Self Store Hose is 5/16" OD Nylon Tube)

ABOUT HOSE TAILS

Hose Tail fittings are designed not to damage the inner wall of the connecting hose. They are not a push and lock style and do require Hose Clamps or "O" Clips to secure the hose.

It should be noted that most fitting manufacturers describe hose in imperial size.
E.g. 4TM4 1/4" x 1/4", while most hose manufacturers describe hose in metric.
