COMPATIBILITY
- See the details below for individual compatibility
While these fittings may fit more applications than what is listed below, these are the fitments that we are aware of. If you need to know if one will fit your application and it is not listed, use the measurement information below to help determine if there are compatible fittings.
OVERVIEW
V2 Quick Connect fittings are found on many OEM vehicles including BMW, VW, Audi, Lamborghini, Ford, Porsche, SEAT, Mercedes, etc.
These Radium Engineering fittings are used with many crankcase ventilation and turbo inlet connectors. They are primarily used for air/oil separation catch cans.
MEASUREMENT
No exact measurement from the actual fitting determines the size (in millimeters). The number associated with the size is actually the inner diameter of the tube (or hose) that will be installed onto the fitting. Shown below is a 19mm V2 quick connect fitting. NOTE: it is not necessarily the ID or the OD of the fitting. The size will be in between these 2 values.

IMPORTANT: Always lubricate the mating O-rings with a light amount of oil prior to installing.
