HP plugs are designed to fit holes with a total diameter tolerance of -O/+01.mm. This tolerance is obtained with a simple drilling operation. HP caps are made of one piece for quick and easy installation. Installation is achieved by simply pushing the steel ball into the socket, allowing the socket to expand, the grooves pressing into the material in the surrounding hole, providing a reliable seal and anchoring of up to 270Mpa. These simple instructions must be followed when installing HP expansion caps:
1. Drill the installation hole to the recommended diameter with a normal drilling operation. Further reaming is NOT NECESSARY.
2. Check the installation hole for the correct depth, diameter and verify that it is free of cutting oils, grease and processing residues.
3. Place an HP expansion plug in the hole so that it bottoms out.
4. Using the correct installation tool, press the HP cap into the hole. The ball must be pressed into the socket below or flush with the edge. The correct tolerance is O/ -0.25 mm.
5. For mass production, fixed or portable pneumatic or hydraulic tools can be used.
6. HP expansion plugs provide reliable performance and high pressure resistance. Periodic pressure tests must be carried out to verify that the installation is correctly carried out.
