GOORY 1/4″ Copper Tubing For HVAC And DIY

The GOORY 1/4″ copper tube features a seamless, coil-form, annealed UNS C12200 copper designed to meet ASTM-B280 standards. With dimensions of 1/4″ OD and 0.195″ ID, the tube provides efficient heat transfer and reliable pressure handling for swamp cooler lines. Its nitrogen charged treatment helps slow oxidation and prolongs lifespan, making it a practical choice for systems exposed to moisture and temperature fluctuations. The 10-foot length allows flexibility in routing between the cooler, pump, and reservoir, reducing the need for splices in short runs.
Key considerations:
– Suitable for low to moderate pressure refrigerant or water circuits in swamp coolers.
– Seamless coil reduces leak points, improving reliability.
– 0.7 mm wall thickness offers a balance between flexibility and durability.
XIFOWE 1/4″ Copper Tube 3/16″ ID, 5 Feet

This XIFOWE copper tube comes in a 1/4″ OD by 3/16″ ID profile with a 5-foot length. It uses a smooth, seamless surface and adheres to ASTM-B280 specifications. The wall thickness is 0.8 mm, offering robust resistance to pressure and external impacts, which is beneficial in swamp cooler lines subject to movement or vibrations. The tube is marketed as a soft coil, enabling easy bending around corners without kinking, a common issue when configuring intake and drain lines for evaporative coolers.
Key considerations:
– Short run suitability for tight installations.
– Improved machinability for custom bends and fittings.
– Long-term durability in humid environments due to nitrogen-treated features.
XIFOWE 1/4″ Copper Tube, 10 Ft, 3/16″ ID

This longer XIFOWE option extends to 10 feet, providing flexibility for installations that require more reach between components of a swamp cooler. The tube maintains a 1/4″ OD with a 3/16″ ID, and a 0.8 mm wall thickness to support higher transient pressures typical in evaporative cooling systems. As with the shorter version, it is a seamless, soft coil product manufactured under ASTM-B280 standards with nitrogen charged treatment for corrosion resistance and oxidation control.
Key considerations:
– Ideal for longer runs without multiple joints.
– Consistent diameter supports predictable fittings and manifolds.
– Durable under recurring temperature and humidity exposure.
YullSorom Copper Tube, 3/8″ OD x 0.328″ ID, 5 Ft

The YullSorom tube offers a 3/8″ outer diameter and a 0.328″ inner diameter with a 5-foot length. The 0.8 mm wall thickness, combined with nitrogen charged treatment, helps resist oxidation and maintain structural integrity in humid environments. This size is useful for swamp coolers with larger tubing needs or when matching to broader inlet/outlet fittings. The seamless coil design minimizes potential leaks and supports efficient coolant flow in compact or challenging installations.
Key considerations:
– Higher flow capacity for larger swamp cooler systems.
– Robust durability against corrosion and environmental exposure.
– Suitable for scenarios where wider tubing is required to prevent bottlenecks.
GOORY 1/2″ Copper Tubing 1/2″ OD x 0.445″ ID, 10 Ft

This GOORY tube provides a larger bore with 1/2″ OD and 0.445″ ID, offering higher throughput for swamp coolers with substantial water circulation needs. The tube length is 10 feet, and it is described as seamless and coil-form. As with other tubes in this collection, it is annealed C12200 copper meeting ASTM-B280 standards, and nitrogen charged treatment aims to curb oxidation and condensation buildup. The increased diameter makes it a strong option for systems with wider manifolds or where long runs are required without frequent joints.
Key considerations:
– Enhanced flow for big evaporative coolers.
– Increased stiffness compared to smaller tubes; plan routing accordingly.
– Durable in moist environments due to protective treatment and alloy composition.
Buying Guide: Copper Tubing For Swamp Coolers
When choosing copper tubing for a swamp cooler, several factors matter beyond basic size. Durability, compatibility with fittings, and resistance to oxidation influence long-term performance. The following insights summarize different perspectives to help you select the best option for your setup.
- Size and compatibility: Match tubing OD/ID to your fittings and manifolds. A 1/4″ or 3/16″ ID often suits compact evaporative coolers, while a 1/2″ bore supports higher flow in larger systems.
- Wall thickness and durability: A thicker wall (around 0.8 mm) improves resistance to pressure changes and external impacts, which can occur when routing tubing through walls or ceilings.
- Seamless vs. coil form: Seamless tubes reduce leak risk, while soft coil tubes offer easier bending. Consider the installation geometry and whether additional fittings will be needed.
- Material quality and standards: Look for tubes that conform to ASTM-B280 and use high-purity UNS C12200 copper. Nitrogen charged treatment helps prevent oxidation and prolongs life in moist environments.
- Length and routing: Plan for minimal joints. Longer runs reduce potential leak points but require precise bending to avoid kinking.
- Application considerations: For swamp coolers, correlate tubing size with water flow requirements and pressure conditions. For higher flow or large installations, a larger diameter may be beneficial.
- Maintenance and accessibility: Ensure tubing is accessible for inspection and possible replacement. Consider corrosion resistance and ease of cleaning to maintain system efficiency.
In summary, selecting copper tubing for swamp coolers involves balancing diameter, wall thickness, and durability with the physical layout of your installation. The products highlighted here provide a spectrum of sizes and build qualities to fit various swamp cooler configurations. Prioritize compatibility with your fittings, and favor seamless, nitrogen-treated options for enhanced longevity in humid environments.
