Installation tools for sealing plugs

Installation tools for sealing plugs, also called expansion plugs, are available both as manual hand tools—ideal for simpler or occasional installations—and as pneumatic tools (air hammer tools) for fast, efficient, and consistent installation in high-volume applications. The choice of tool depends on the demands of the application and the working environment. With the right equipment, you ensure correct and reliable installation every time.

How installation works

Installation takes place in a few simple steps: the sealing/expansion plug is placed into the pre-drilled hole in the hydraulic manifold, and the ball or pin inside the plug is driven down using the installation tool. This causes the sleeve to expand outward, pressing tightly against the walls of the hole, creating a secure and durable seal—even under high pressure.

For sealing auxiliary drill holes

To seal auxiliary drill holes in hydraulic systems, sealing plugs are used. These plugs expand mechanically during installation, creating a pressure-resistant and reliable seal.
