Injection Packer75mm

Injection Packer75mm About

91 000 74051 Injection packers are ports or fittings inserted into drilled holes in concrete, masonry or other structural elements so that injection materials (epoxy, polyurethane, acrylate gels etc.) can be pumped into cracks, voids, or joints. They act as sealed access points so the injection grout or resin enters the structure under pressure without escaping.
Important Specifications / What to ChooseDiameter of packer: depends on how much flow you need and what crack size / pressure. Common diameters 6 mm, 10 mm, 13 mm, 16 mm etc. Length / Shaft length: Longer packers help in weak or deteriorated concrete so they grip well in the hole without blowing out. Short ones are fine for shallow cracks. Valve type / fitting type: Zerk type vs Button-Head vs Anti-Return Valve. Anti-return valves help prevent backflow and ease multiple injections. Button-head or flat-head help with fast hose connection. Material strength & corrosion resistance: Steel gives high strength and good pressure resistance; aluminum/brass cheaper; plastic lighter. Choose depending on environment and pressure.
Q. What diameter should I choose? Depends on volume / flow and crack/void size; 10-13 mm common for concrete crack injection.Q. Can these packers be reused? Some metal packers may be reusable; plastic ones often single use.Q. What injection materials can be used? Epoxy, PU, acrylate, silicate etc. Check compatibility with valve and packer material.Q. How to finish after injection? Pull out or break off the packer stem if needed, seal hole with patch repair mortar.
