This TiAL Sport diaphragm assembly is a direct replacement for Q and QR blow-off valves, supplying the diaphragm and associated components needed to refresh a BOV. Use it when the original diaphragm shows wear or damage to restore correct valve response and sealing. The assembly is intended to maintain the valve’s designed movement and help preserve consistent venting or recirculation behavior.
