Best for: Quick, small-scale connections and service tasks in compact systems.
Why selected: Small footprint and good flexibility make it convenient for tight spaces and retrofit jobs.
Caution: Short length may require additional joints for longer runs; ensure compatibility with fittings.
Buying Guide
- What size should I choose? Consider the system’s refrigerant capacity and space. Smaller OD tubes (1/4″) fit tight spaces; larger tubes (3/4″, 3/8″) carry more refrigerant and support bigger units.
- Why choose nitrogen-charged tubes? Nitrogen charging helps prevent oxidation and impurities, extending life and reducing leaks in many applications.
- Is coil vs. straight length important? Coils simplify handling and storage; straight lengths provide clean, straight runs. Choose based on installation layout and bend requirements.
- What about ASTM B280 compliance? This standard ensures the tubing is appropriate for refrigeration and HVAC use, with consistent composition and performance.
- How to plan for bends and fittings? Account for minimum bend radii and available fittings. Excessive bending can cause micro-cracks or flow restrictions.
Practical considerations
- Material purity: All selected products are UNS C12200 copper, a common grade for refrigeration work.
- Length planning: Match tubing length to the actual run to minimize waste and ensure proper routing.
- Installation environment: For DIY, choose easier-to-handle sizes and shorter lengths to reduce complexity.
