TiAL Sport QRJ 41mm Blow-Off Valve - 1.5 PSI Spring - Black

The TiAL Sport QRJ is a compact 41mm modular blow-off valve built for a wide range of configurations, flowing 91 lb/min. It runs primarily as a recirculating or diverter valve, with a diffuser outlet flange available for vent-to-atmosphere use, and its side-mounted inlet means boost can never push the valve open. Construction is all billet aluminum with a black anodized cap, a Nomex-reinforced silicone diaphragm and an M10 vacuum port; it ships with the 1.5 PSI spring installed, while inlet and outlet flanges are sold separately to match your plumbing.
