KabSeal Pro: An Airtight Finish for Lunos Penetrations

A practical upgrade for any Lunos installation in new builds and retrofits. Lunos Canada has partnered with Partel Canada to offer a simple, durable solution for airtight sealing around Lunos pipe sleeves during installation.

When installing a Lunos e², e²60, or Ego system, the wall penetration is one of the most critical points in the entire ventilation assembly. Installers often look for a clean, dependable way to finish the seal around the pipe sleeve. The KabSeal Pro airtight pipe grommet offers a clean, reliable way to maintain continuous airtightness around Lunos wall penetrations—without relying on tapes, improvised solutions, or site-built detailing.

KabSeal Pro is a flexible EPDM grommet designed to provide a durable, long-term seal around pipes and conduits passing through the building envelope. For installers and builders working with Lunos systems, it delivers a simple and robust solution that aligns with high-performance building expectations.

Airtightness Made Simple

Lunos installations benefit from clean, consistent detailing around the wall sleeve. KabSeal Pro provides a straightforward way to complete this connection with a tidy, professional finish. The flexible EPDM collar conforms neatly to the Lunos sleeve and integrates smoothly with common air-barrier membranes, offering installers a ready-made alternative to tapes or improvised site-built solutions.

Durable Exterior Detailing

KabSeal Pro incorporates a flexible EPDM interface that pairs well with the membranes typically used in Canadian construction. Its elasticity and material resilience help create a neat, weather-resistant finish around the penetration, making it a practical accessory for builders who want a dependable way to complete the exterior detail around a Lunos sleeve.

Fast, Clean Installation

One of the advantages of KabSeal Pro is its simplicity. The grommet requires no specialized tools, no curing time, and no multi-step adhesive process. It slides easily over the sleeve and settles into place, creating a clean, uniform seal in seconds. This makes it particularly useful on job sites where installers appreciate speed, repeatability, and minimal fuss—whether the project is a new build, a modular assembly, or a small retrofit.

Works Seamlessly With Modern Air-Barrier Systems

KabSeal Pro is compatible with the air-barrier and weather-resistive membranes commonly used in Canadian construction, allowing installers to achieve a clean, integrated finish around the Lunos sleeve. The combination provides a tidy, professional detail that aligns with expectations for high-performance building envelopes.

A Practical, Cost-Effective Upgrade

Although not required for Lunos installations, KabSeal Pro offers meaningful value for builders, tiny-home manufacturers, modular construction teams, and homeowners alike. It offers a simple, consistent way to complete the penetration detail, reduces potential rework, and helps maintain the overall quality of the installation. For many projects, it becomes a small upgrade that supports long-term durability and workmanship.

In a typical installation, the grommet is applied after the opening is cored, the Lunos sleeve is placed, and the air-barrier or weather-resistive barrier has been installed. Once those steps are complete, KabSeal Pro is simply slid over the sleeve and pressed into position against the membrane. The remaining interior and exterior components are then installed as usual. This sequence results in a clean, durable penetration detail that performs well across a range of climate conditions and building types.
