GFB 4AN Vacuum Fitting – Mach 2/Hybrid/Respons/Deceptor Pro BOV – Universal

Application: Universal – GFB Mach 2 / Hybrid / Respons / Deceptor Pro II BOVs
Part Type: 4AN Vacuum Fitting


GFB builds some of the most popular blow off valves on the market, and this AN-4 vacuum adaptor is a genuine GFB accessory designed to upgrade the standard brass hose barb on their Mach 2, Hybrid, Respons and Deceptor Pro II BOVs. If you are running higher boost and want the durability and clamping security of braided vacuum line, this fitting lets you ditch the barb and hose clamp setup for a proper AN connection.

This listing covers the SKU 6215 fitting only, machined from stainless steel and supplied with a Viton o-ring for a reliable seal against the BOV body. It suits the Mach 2, Hybrid, Respons and Deceptor Pro II range where the vacuum port has a female hex machined into the hole.

Important: Early versions of these GFB BOVs used a round hole with a different thread and are not compatible with this fitting. Check your BOV's vacuum port for a female hex before ordering.
