Auburn S222-36 Oil Line

The Auburn S222-36 Oil Line is a professional-grade 36" 3/8" flare flexible oil line designed to provide reliable fuel delivery in residential and commercial heating systems. Engineered with a durable braided steel covering, this high-performance hose is specifically built for use as oil burner suction and return lines. Its flexible construction is the ideal solution for swing-out burner doors and oil de-aerator installations, allowing for easy maintenance access without disconnecting the fuel supply. This versatile component supports No. 1 and No. 2 heating oil, as well as various BioHeat blends. With a technical rating of 145 PSI at temperatures up to 200°F, it ensures a secure, leak-free flare connection for critical HVACR applications. By replacing rigid copper with this flexible oil line, technicians can reduce vibration transfer and eliminate the risk of kinking during routine burner service.

Key Benefits

• Industrial Durability: The braided steel covering protects the inner line from abrasion and environmental wear.
• Enhanced Flexibility: Simplifies the installation of swing-out doors, allowing the burner to be serviced without straining the fuel connections.
• Broad Compatibility: Suitable for standard heating oils and modern BioHeat fuel blends (B20 to B100).
• Leak-Resistant Design: Precision-engineered 3/8" flare connections provide a high-pressure seal for suction and return applications.
• Simplified Maintenance: Facilitates complex routing in tight spaces where traditional copper piping is difficult to maneuver.
