Largest Off-the-Shelf Splittable Mechanical Duct Sealing Systems for Retrofit Installations

Introduction

In the industrial world, sealing solutions play a pivotal role in maintaining the integrity and efficiency of installations. Whether it's sealing a water line, power cable, or communication lines in core drills or wall sleeves, the need for reliable and versatile sealing systems is paramount. Universal mechanical duct seals, particularly those made in Germany, offer an innovative and superior alternative to traditional press seals like pressing water split seal inserts.

Precision Engineering at Its Finest

Our German-engineered universal mechanical duct seals provide you with unparalleled opportunities for effective sealing of core drills and wall sleeves accommodating one or multiple pipes. These seals range from options suitable for first-time installations to splittable seals designed for retrofit applications involving pipes and cables that are already in place. This versatility ensures that we can offer the ideal mechanical duct seal for every requirement and task, whether tailor-made to precise measurements or suitable for universal on-site use, all while being quick and cost-effective.

Peelable Layer Technology for a Perfect Fit

One of the standout features of our seals is the innovative peelable layer technology / segmented ring technology. Each seal consists of layers that can be easily pulled and cut away to match the exact outer diameter (O/D) of your cables or pipes. This design allows for a flexible and precise fit, accommodating various cable sizes without the need for multiple seal types. The result is a flexible sealing solution that ensures optimal protection against environmental hazards.

Advantages Over Traditional Press Seals

While traditional press seals have been commonly used, our universal mechanical duct seals stand out due to several key advantages:

  • Splittable Design for Retrofit Installations: Unlike closed seal inserts that are only suitable for new installations, our seals can be split and installed around existing cables and pipes, making them ideal for retrofit projects.

  • Peelable Layer Technology: Our seals feature segmented layers that can be peeled & cut away to match the exact outer diameter (O/D) of the cable or pipe, ensuring a flexible and precise fit.

  • Patented Torque-Rated Nut: Simplifies installation by ensuring correct tightness without the need for special tools. The nuts "click" & spin freely once optimal tightness is achieved, preventing under-tightening or over-tightening, achciving a consistent failsafe duct sealing system.

  • High-Quality German Engineering: Manufactured in Germany, our seals are precision-engineered from high-grade, non-corrosive stainless steel V2A, ensuring durability and reliability.


Easy Installation with Patented Torque-Rated Nut

Installation is straightforward, thanks to the unique, patented torque-rated nut. This feature guarantees that all tightening nuts are correctly torqued without the need for special tools like torque wrenches. The nuts are designed to "click" & spin freely once the optimal tightness is achieved, preventing both under-tightening and over-tightening. This not only simplifies the installation process but also ensures a consistent and failsafe reliable seal every time.


Ideal for Water Lines, Power Cables, and Communication Lines

Our universal mechanical duct seals are perfect for sealing:

  • Water Lines: Providing robust protection against water ingress, even in ducts with running water issues.

  • Power Cables: Ensuring safety and preventing gas infiltration or humidity that could compromise electrical systems.

  • Communication Lines: Protecting vital communication infrastructure from environmental hazards and rodent intrusion.
