Fox Nitrogen Pellet Valve Assembly - 7/16-20 Thread (Needle Fill)
Genuine Fox Racing Shox Nitrogen Pellet Valve Assembly.
This is the "Pellet Style" fill port used on many older Fox shocks. It uses a rubber pellet (included) to seal the nitrogen charge and requires a Needle Fill Tool to service.
Specs:
- Thread Size: 7/16"-20 (O-Ring Boss)
- Valve Type: Nitrogen Pellet (Not Schrader)
- Fill Method: Requires Nitrogen Needle Tool
Original Fox Nitrogen Port
This is the authentic replacement nitrogen valve for older Fox shocks that use the "Pellet" sealing system. Unlike modern Schrader valves (which work like a tire stem), this assembly uses a compressed rubber puck to seal high-pressure nitrogen inside the reservoir.
Critical Fitment Notes
- Requires Needle Tool: You cannot fill this valve with a standard tire chuck. You must use a Motion Pro or Fox Nitrogen Needle Tool to pierce the rubber pellet.
- Thread Size: This fitting has 7/16"-20 threads. (Note: Newer Fox shocks often use smaller 5/16"-32 threads. Please measure your port before ordering).
- Pellet Included: Comes complete with the brass housing, O-ring, and the rubber sealing pellet pre-installed.
Common Applications
- Older Fox 2.0 and 2.5 Series shocks.
- OEM shocks on older snowmobiles (Arctic Cat, Polaris) and UTVs.
- Replaces the "Self-Healing" rubber valves found on many early reservoir caps.
