Screw-in Plug (block off recirc or atmo outlet)
If you have a GFB blow-off valve with two outlets and want to plug one of them, this is the plug to use. It replaces either a trumpet or recirc outlet to effectively disable the venting port. On Hybrid valves for example, it is used to change from 50/50 to full atmosphere or full recirc venting, by plugging the appropriate outlet.
It is also commonly used to plug the trumpet outlet of the Stealth FX and Deceptor Pro in order to pass roadworthiness examinations, by preventing the valve from "easily" being adjusted to atmosphere-venting.
*Screws into any GFB trumpet or plumb back outlet. Valves manufactured before 2003 require thread adaptor #6309
