️ HIGH QUALITY MATERIALS FOR LONGER RELIABILITY: Made of smooth, flame retardant synthetic rubber with high resistance to temperatures and wear for optimal tightness. Reinforced by rust-proof, galvanized steel components and anti-slip screws for lasting stability. Note: Our product may have a typical rubber smell. Please ventilate it in a well-ventilated place before first use.
️ Excellent sealing performance: By tightening the steel screws evenly, the sealing ring is compressed, ensuring a tight fit both around the drill holes in the wall and around the cables. This ensures a reliable seal even at pressures of up to 1.5 bar, making the product the ideal choice for demanding construction projects.
Reliable sealing for pipe: our ring space seal forms a flexible and waterproof barrier between wall breakthrough and pipe. Guarantees a reliable, ring-shaped seal for gas, water, sewage pipes and electrical cables in construction, industry and solar systems. Protect your building reliably from moisture, dust and pest infestation.
Flexible adjustment for optimal sealing: using the onion ring technology, you can manually adjust the seal to the exact dimensions of your pipes. The universal solution for all diameters from 0-55 mm. For best results, please measure the diameter of your cable or pipe first.
Flexible & Quick Installation Just cut a suitable opening into the ring space seal, then open the side to sheathe the cable before inserting it into the central bore(99-105mm). Tighten the screws to achieve an instant seal and secure locking - flexible installation with firm grip.
