Abstract
A hydraulic gun for injecting sealant including an elongated barrel in which a floating piston separates a bore onto a material receiving chamber and a hydraulic fluid chamber. A manual hydraulic fluid pump assembly is mounted on the barrel in parallel juxtaposition. Mounting blocks serve to join the hydraulic pump assembly to the barrel and to provide support feet for the gun. The hydraulic pump is mounted on the barrel in a manner that permits the gun to be operated in a vertical orientation with continued supply of hydraulic fluid.
