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 spring 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. This port can be injected thru the plunger using any of our cartridge systems. The design allows resins to move into the void area with the fear of air entrainment.
