Surface mount epoxy crack injection port. 1/4" OD (3/16" ID) adapts to many static mixing nozzles. Includes crimp-it collar (see below) to prevent backflow of material before it has cured.
For injecting bulk epoxy use plastic injection port coupling #791-3 with any of our DL-45 or DL-59 style bulk guns with 426-G01 front caps. Also can be used with standard metal nozzles with 1/4" ID. Ports also available in drill-in style 772-4.
