Fox DHX/VAN Bleed Fitting (Fox 803-00-463 Equivalent)
 
This is a WSS brand, model STBP1103 bleed fitting. It has the same threads on both ends as the OEM Fox 803-00-463 fitting. 
 
This bleed fitting threads onto the MTB Hydraulics bleed syringe like a Fox bleed fitting. 
 
This fitting is used to bleed most older Fox shocks from as early as the DHX coil shock from 2005, all the way through the DHX Air, DHX RC2/4, 2016-2023 Float X2, 2016-2023 DHX2, etc. It is also useful to bleed through the screw hole on most Fox IFPs such as the one found in the Float DPX2, Float X, DHX2, Float X2, etc. This fitting also works for bleeding Push 11.6 shocks.
 
The easiest way to identify if a Fox shock uses this fitting is by 2 mm (or the imperial equivalent) allen head bleed screw. If the bleed screw is torx head, then it uses the 803-00-463 fitting.
