FX Boss parts

Update on urethane D90 orings for FX Boss inlet air valve. While the oring worked for a short time, the urethane is not a strong enough material for a lasting repair. FxUSA has a new parts out let headed up by Ernest Rowe 1-866-639-0772 and they can furnish you with the o-ring of proper strength. Thanks to all who posted responses to help me with this and I hope the info on FX will help someone in the future.
