TADERUILY 25 Ft Mini Split Copper Tubing Pipe Extension Set
This 25-foot copper tubing expansion kit from TADERUILY features tubing with outer diameters of 1/4″ and a thicker 1/2″ pipe to accommodate specific mini split models requiring a larger diameter line. Like other models, it withstands high and low pressure and suits air conditioning and heat pump use, backed by copper construction for durability and resistance to leaks.
findmall 50 Ft Air Conditioning Copper Tubing Hose Extension
The findmall 50-foot copper tubing hose extension offers one of the longest lengths available for mini split systems. Its 1/4″ and 3/8″ copper tubes are protected by thickened insulation cotton, ensuring internal tubing remains safe from damage. The copper material provides good ductility and hardness, which helps extend the service life of the line set. It’s designed to keep the insulation temperature under 80°C for optimal performance.
Buying Guide for Mini Split Copper Line Sets
Choosing the right mini split copper line set is driven by several factors crucial for HVAC efficiency and longevity. Consider these key points to ensure optimal performance and compatibility:
- Length: Measure the distance between your indoor and outdoor units accurately. Line sets come in lengths ranging from 10 feet to 50 feet or more. Overestimating slightly is safer than underestimating the needed length.
- Copper Tube Size: The most common sizes are 1/4″ (liquid line) and 3/8″ (suction line). Some systems require different dimensions like 1/2″. Verify your mini split’s specific requirements before purchasing.
- Wall Thickness: Thicker copper tubing walls (e.g., around 0.65mm or higher) provide enhanced durability and resistance to leaks under high pressure conditions.
- Insulation Quality: Good insulation preserves refrigerant temperature and prevents condensation. Look for triple-layer insulation systems combining polyethylene film, foam, and insulating cotton for superior thermal protection.
- Pre-Flared Ends and Nuts: Pre-flared tubing with compatible nuts simplifies installation and reduces the risk of leaks. Confirm the nut sizes fit your mini split connections.
- Temperature & Pressure Resistance: Choose a line set rated to endure both high and low temperature extremes encountered in HVAC applications, ideally stable down to -40°F and up to 248°F.
- Compatibility: Confirm the product is suited for mini split air conditioners, ductless systems, or heat pump models as applicable.
Considering these factors together ensures you choose a reliable and efficient mini split copper line set, promoting optimal cooling and heating system performance while minimizing maintenance and leak risks.
