A rigid port used for the injection of our resin systems on various substrates. This port will accept premixed “A” & “B” components into its reservoir for large volume injection processes without the requirement of a pump. The injection is completed via a plunger on the reservoir and a rubber band system providing a constent pressure on the mixed resins to maintain a positive pressure on the injection process. Resins are easily visible through the polyurethane translucent reservoir. Reservoir can be repeatedly refilled without the fear of injecting air into the void cavity.
