As a specialized manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory is proud to present our high-quality Stainless Steel Serpentine Coil (Model: 304, 3/8 Inch OD, 0.032 Wall, 15 Ft, 200 PSI, 8 FPI). Established in 1998, we have been serving global markets including North America, Europe, and Southeast Asia, with annual export values reaching US$5–10 million. Our coils are engineered for superior heat transfer efficiency and durability, making them an ideal choice for condensers, evaporators, and industrial cooling systems.
This serpentine coil is crafted from premium 304 stainless steel, offering excellent corrosion resistance and long service life even in demanding environments. The 3/8-inch outer diameter and 0.032-inch wall thickness ensure a perfect balance between strength and flexibility, while the 15-foot length provides ample coverage for various applications. With a working pressure rating of 200 PSI and 8 fins per inch (FPI), this coil delivers consistent performance under moderate pressure and temperature conditions.
Key Features & Technical Specifications
- Material: 304 Stainless Steel – exceptional corrosion resistance, suitable for water, oil, and mild chemical environments.
- Dimensions: 3/8" OD x 0.032" wall – optimized for efficient heat transfer and easy installation.
- Length: 15 ft (4.57 m) – pre-coiled for convenient handling and integration into systems.
- Pressure Rating: 200 PSI (13.8 bar) – reliable for most HVAC and refrigeration applications.
- Fin Density: 8 FPI – provides a good balance between heat transfer surface area and airflow resistance.
- Coil Configuration: Serpentine (U-bend) design – maximizes contact area and reduces fluid velocity for better heat exchange.

Our serpentine coils are manufactured using advanced bending and welding techniques to ensure consistent pitch and radius. The 304 stainless steel construction provides excellent resistance to oxidation and scaling, making it suitable for both high-temperature and low-temperature applications. The 8 FPI fin density is optimized for typical air-cooled condenser and evaporator coils, delivering efficient heat transfer without excessive pressure drop.
Each coil undergoes rigorous pressure testing and visual inspection to guarantee leak-free performance. The 200 PSI rating covers a wide range of commercial and industrial systems, including HVAC, refrigeration, heat pumps, and process cooling equipment. The 3/8-inch OD is a standard size that easily connects to common tubing and fittings.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum operating temperature for this coil?
A: 304 stainless steel can typically handle temperatures up to 870°C (1600°F) in continuous service, but for optimal performance in heat exchanger applications, we recommend staying below 400°C (752°F). -
Q: Can this coil be used in potable water systems?
A: Yes, 304 stainless steel is safe for drinking water applications. However, local regulations may require specific testing; please verify with your local authorities. -
Q: Is the coil supplied with fittings or connectors?
A: The coil is supplied as a bare coil without fittings. Standard compression or solder fittings for 3/8" OD tubing are widely available and can be used. -
Q: How is the coil packaged for shipment?
A: Each coil is individually wrapped and secured in a sturdy carton or wooden crate to prevent damage during transit. Bulk packaging is available for large orders. -
Q: Can you provide coils with different fin densities?
A: Yes, we can customize fin density (e.g., 10, 12, 14 FPI) based on your heat transfer requirements. Please contact our sales team for details. -
Q: What is the bending radius of the serpentine shape?
A: The standard inside bend radius is approximately 1.5 times the tube OD (about 0.56 inches for 3/8" OD). Custom radii are available upon request. -
Q: Do you test the pressure rating of each coil?
A: Yes, we perform 100% hydrostatic pressure testing at 1.5 times the rated pressure (300 PSI) to ensure leak-free performance. -
Q: What is the lead time for custom orders?
A: Standard coils are in stock and ship within 3-5 business days. Custom orders typically require 15-20 working days depending on complexity.
