The PENTENS Injection Packer is a high-quality tool used in pressure injection systems for the delivery of PU (polyurethane), epoxy resins, and other sealants into concrete cracks and voids. Designed for reliable performance in crack repair, waterproofing, and structural rehabilitation, this packer ensures a tight seal and effective material delivery under high pressure.
High-Pressure Tolerance – Capable of withstanding pressure levels typically used in injection processes.
Durable Construction – Made with corrosion-resistant zinc-plated steel or aluminum body for long-lasting use.
Rubber Expansion Sleeve – Expands to create a tight seal inside the drill hole, preventing backflow of injection materials.
Easy Installation – Simple to insert and tighten using standard hand tools.
Leak-Proof Design – Minimizes material waste and improves injection efficiency.

Drill a hole (typically Ø12–14 mm for Ø13 mm packers) at 45° angle into the crack.
Insert packer tightly into the drilled hole.
Tighten using a spanner to expand the rubber sleeve.
Connect injection pump and begin material injection.
Remove and dispose of or clean the packer after curing, depending on the project type.
