A unique flexible port used for the injection of our cartridge resin systems on various substrates. This port includes a one way check valve to purge air during the injection process but closes when the resin system hits the valve. The bladder is designed to expand with the flow of resin product to maintain a positive pressure into the void area. Simple to distinguish the port that requires additional resins to complete the injection process. Will not over-pressure a void area to create baseplate distortion.
