Product Introduction

Rubber‑plastic insulation tubes for split air conditioners are closed‑cell elastic foam tubes specially for air‑conditioner copper refrigerant pipes. Made of NBR‑PVC by vacuum microcrystal foaming technology. Available in black, red and blue for pipeline identification. It wraps the connecting copper pipes between indoor and outdoor units, delivering cold‑keeping, anti‑condensation and noise‑reduction performance. Standard insulation accessory for residential & commercial split air conditioners.

Key Features

1. Superior Cold Insulation & Anti‑condensation High closed‑cell structure with low thermal conductivity to reduce cooling loss. High vapor diffusion resistance prevents condensation dripping, protecting ceiling and wall from damp and mildew.
2. Multi‑color for Pipeline Identification Red, blue, black options to distinguish high‑pressure and low‑pressure pipes conveniently, improve installation efficiency.
3. Flexible & Bend‑resistant High elasticity, no cracking upon bending. Perfect for turning and wall‑penetrating wiring, fits tightly on copper tubes without delamination.
4. Fire‑retardant Safety Complies with GB 8624‑B1 flame‑retardant grade, low‑smoke halogen‑free, self‑extinguishing for safe operation under air‑conditioner working temperature.
5. Vibration & Noise Reduction Foam buffer structure absorbs vibration from compressor, lower pipeline resonance noise for quieter indoor environment.
6. Aging & Moisture Resistance Good ozone and humidity resistance. Hardly pulverize, shrink or crack after long‑time service, suitable for indoor and embedded outdoor installation, long service life.
7. Easy Installation Easy to cut, directly sleeve on copper pipes. Joints sealed with special foam adhesive for fast construction.
