The TechT Stainless Steel Phenom Flex Valve Pin replaces the plastic stock flex valve retaining pin on the X7 Phenom Paintball Marker. It is constructed of 100% Stainless Steel and treated with a black oxide finish to match the Phenom. Many players have requested this replacement due to the stock pin cracking and/or breaking. This pin will assure that your phenom never goes down due to pin issues. The pin includes 2 sets of o-rings in the package.
