Robertshaw 11-193 Aluminum Tubing

The Robertshaw 11-193 is a professional-grade 1/4" aluminum tubing roll designed for high-reliability applications in HVACR systems. This 50-foot coil is engineered specifically for use as pilot gas lines, refrigeration connections, and general service applications where corrosion resistance and ease of forming are critical. Constructed from 1435 aluminum alloy, this tubing provides the ideal balance of structural integrity and workability for the field technician. It meets rigorous ASTM B483 standards, ensuring consistent wall thickness and performance under pressure.

With a 0.035" wall thickness and a dedicated 90 PSI pressure rating, the 11-193 is built to handle standard gas delivery without the risk of kinking or premature failure. The material offers an 11,000 tensile strength and 9,500 yield strength, featuring a 25% elongation rate that allows for precise tube bending around tight furnace and boiler components. Whether you are performing a standing pilot retrofit or replacing a damaged pilot assembly line, this tubing ensures a secure, leak-free connection when used with standard 1/4" compression fittings.

Key Benefits

• Corrosion-Resistant Alloy: The 1435 aluminum alloy is specifically chosen for its longevity in environments exposed to combustion byproducts.
• Field Workability: High elongation properties allow for tight-radius bends without collapsing the inner diameter.
• Standardized Compliance: Fully compliant with ASTM B483, providing predictable performance for commercial and residential installations.
• Pressure Integrity: Rated for up to 90 PSI, making it suitable for a wide variety of secondary gas and refrigeration lines.

Common Questions

Is this tubing compatible with standard compression fittings?
Yes, the 1/4" outside diameter (OD) and 0.035" wall thickness are designed for standard HVACR compression ferrules and nuts.

Can the Robertshaw 11-193 be used for high-pressure refrigerant lines?
This tubing is rated for 90 PSI and is primarily intended for pilot gas lines and low-pressure applications. Always verify your system's peak operating pressure before installation.

Does this roll include any fittings or orifices?
This item is the raw 50-foot aluminum tubing roll only. Fittings and gas orifices must be sourced separately based on the specific appliance requirements.
