MRCOOL ADVSLEEVE — Advantage Series Wall Entry Sleeve Kit
The clean, professional solution for routing mini-split line sets through exterior walls — protects your installation and delivers a finished look.
What Is the MRCOOL ADVSLEEVE?
The MRCOOL ADVSLEEVE is a wall entry sleeve kit specifically designed for the MRCOOL Advantage Series mini-split systems. It provides a clean, weatherproof passage for refrigerant line sets, communication cables, and condensate drain lines through exterior walls during mini-split installation. The sleeve protects the line set from abrasion at the wall penetration point and creates a professional, finished appearance — eliminating the rough, unfinished hole that results from drilling alone.
This accessory is an essential finishing component for any Advantage Series installation where aesthetics and long-term line set protection matter. The sleeve is made from durable UV-resistant plastic and includes a matching cap/escutcheon plate that covers the wall opening from the interior side.

Installation Tips
- Drill the correct hole size: Before installing the sleeve, drill a hole through the exterior wall that matches the sleeve's outer diameter. Typically 3.5" for Advantage Series line sets. Angle the hole slightly downward toward the exterior to ensure condensate drains outward.
- Install before threading line sets: Insert and secure the sleeve in the wall before feeding the line set through. This is much easier than trying to install the sleeve after the line set is already in place.
- Seal around the sleeve: Apply weatherproof caulk or foam sealant around the exterior edge of the sleeve where it meets the wall to prevent air infiltration, moisture, and pest entry.
- Use with LineGuard for best results: Pair the ADVSLEEVE with MRCOOL LineGuard line set cover kits for a completely finished, professional-looking installation from the wall exit point to the outdoor condenser.
- Compatibility note: The ADVSLEEVE is designed specifically for the Advantage Series. For DIY Series systems, use the MRCOOL MCSLEEVE instead.
Frequently Asked Questions
What is the difference between the ADVSLEEVE and the MCSLEEVE?
The ADVSLEEVE is designed for the MRCOOL Advantage Series mini-split systems, while the MCSLEEVE is designed for the DIY Series. They may differ slightly in diameter and fit. Always use the sleeve that matches your specific MRCOOL series to ensure a proper fit.
Do I need a wall sleeve for my mini-split installation?
A wall sleeve is not strictly required, but it is strongly recommended. Without a sleeve, the line set rests directly against the raw edge of the drilled hole, which can cause abrasion damage to the insulation over time. The sleeve also provides a cleaner finished appearance and helps seal the wall penetration against air, moisture, and pests.
What size hole do I need to drill?
The required hole size depends on the sleeve's outer diameter. For the ADVSLEEVE, drill a hole that matches the sleeve's outer diameter — typically 3.5 inches. Always check the product dimensions before drilling. Drill the hole at a slight downward angle toward the exterior (approximately 5°) to encourage condensate drainage away from the building.
