Technical Specifications Product Type: Wall Sleeve Length (Inches): 4" – 7.5" (Telescoping) Width (Inches): 3" Features: Telescoping, UV-Resistant, Indoor/Outdoor Brand: RectorSeal | MPN: 83017 Material: PVC (Polyvinyl Chloride) Compatibility: Mini-Split Condensate Drain Hoses (MRCOOL DIY) Country of Origin: Japan 💡 Pro Tip: The RectorSeal 83017 sleeve is about 1/2" narrower than the standard 3.5" sleeve used on MRCOOL DIY Series systems. This is because MRCOOL’s Quick Connect line sets have a larger diameter than traditional flare-style lines. You can still use this sleeve with pre-charged line sets — simply separate the individual lines slightly before feeding them through, and finesse the insulation to avoid tearing the inner lining. With a bit of care, it provides a snug, professional-looking fit for DIY installations.
