Steel Injection Packer with Conical Head Nipple

Product Description

The Steel Injection Packer with Conical Head Nipple is a high-pressure drill (mechanical) injection packer manufactured from solid steel and fitted with a special adhesive rubber sleeve. It is used to deliver polyurethane and epoxy injection resins under pressure into cracks, voids, and joints in concrete and masonry structures.

The conical head nipple is the universal connection format used by virtually every injection gun, high-pressure injection pump, and check-valve hose on the market — making this packer drop-in compatible with the equipment already in your kit.

Characteristics and Advantages

• Steel body — withstands the high injection pressures generated by twin-component PU and epoxy pumps without deformation
• Adhesive rubber sleeve — expands when the packer body is tightened, gripping the drill hole and creating a positive seal against blow-back
• Conical head nipple — universal industry-standard fitting; works with every brand of injection gun, hose, and pump
• Versatile resin compatibility — equally suited to flexible polyurethane foams, semi-rigid PU resins, and rigid two-component epoxy resins
• Reusable — after the resin has cured, the head nipple can be removed and reused on the next packer in the next job

Application Instructions

1. Mark the injection points along the crack at the spacing specified by the resin manufacturer (typically 100–250 mm depending on crack width and substrate thickness).

2. Drill the holes at a 45° angle across the crack using a 14 mm SDS masonry drill bit. Drill depth should be at least two-thirds of the substrate thickness so the rubber sleeve seats fully inside the concrete.

3. Blow out the holes with compressed air to remove all dust and loose debris that would otherwise prevent the rubber from sealing.

4. Insert the packer into the drill hole until the head is flush with the surface.

5. Tighten the packer body using a spanner — this expands the adhesive rubber sleeve, locking the packer into the hole and creating a pressure-tight seal.

6. Connect the injection gun or pump hose to the conical head nipple.

7. Inject the resin under pressure until you see resin returning from the next packer along the crack. Close that packer’s check valve, move to the next, and repeat until the full crack length is filled.

8. Allow the resin to cure for the time specified on the resin technical data sheet.

9. Remove the head nipples for reuse. The packer body remains permanently in the structure and is cut flush with a grinder after curing.

Applications

• Concrete crack repair — Seal structural cracks in walls, slabs, beams, and columns
• Waterproofing — Stop active leaks in basements, tunnels, and underground structures via PU foam injection
• Structural rehabilitation — Restore monolithic strength to cracked concrete with epoxy injection
• Joint and construction-joint sealing — Re-seal cold joints in concrete tanks, dams, and retaining walls
• Brickwork and masonry repair — Inject resin into delaminated or cracked masonry
