Robertshaw 4590-069 Ferrule

The Robertshaw 4590-069 is a high-performance 1/4" breakaway ferrule designed for precision reliability in HVACR pilot line applications. Engineered for a secure, leak-proof seal, this brass compression sleeve is compatible with 1/4 inch O.D. copper or aluminum tubing commonly found in gas valves and pilot burner assemblies. Featuring a specialized breakaway design, it ensures a uniform crimp around the tubing wall, preventing over-tightening and potential stress fractures in the line. This OEM-grade Robertshaw component is a critical gas valve pilot fitting for field technicians performing maintenance on residential and commercial heating systems. By maintaining a gas-tight connection, it facilitates consistent pilot flame stability and prevents nuisance service calls related to line leaks. This 1/4 inch pilot ferrule is built to withstand the thermal cycling typical of furnace and boiler environments, making it the preferred HVAC replacement part for ensuring system integrity and long-term durability in the field.

• Precision Fit: Specifically machined for 1/4" O.D. tubing to ensure leak-proof pilot line performance.
• Breakaway Design: Engineered to snap at the correct torque, providing a tactile indicator of a proper seal.
• High-Grade Brass: Resistance to corrosion and mineral buildup, essential for HVACR gas line fittings.
• Contractor Grade: Streamlined installation for Robertshaw gas valve pilot assemblies.

Is this ferrule compatible with aluminum pilot tubing?
Yes, the Robertshaw 4590-069 is designed for use with both copper and aluminum 1/4" O.D. tubing in low-pressure gas applications.

Can this breakaway ferrule be reused after the pilot line is disconnected?
No, fitting a new 1/4 inch compression ferrule is required whenever a pilot line is detached to maintain a gas-tight seal and meet safety standards.

Does this fit all Robertshaw pilot burner assemblies?
This part fits most standard Robertshaw and competitive pilot burners requiring a 1/4" breakaway sleeve, but always verify the O.D. of your specific tubing before installation.
