RaceFlux O-Ring Boss Plug
RaceFlux O-Ring Boss Plug
The low-profile way to block an ORB port: this socket-style plug sits nearly flush in the port, drives with an Allen key, and seals on its Viton O-ring against the port face — no sealant, no tape, and it reseals reliably every time. The MilSpec Type III hard anodized finish shrugs off repeated wrenching and heat cycles.
