Robertshaw 4590-065 Ferrule
The Robertshaw 4590-065 Ferrule is a critical component for technicians performing maintenance or installation on gas-fired equipment. This 1/8" breakaway ferrule is engineered specifically for secure attachment of pilot burner tubing and capillary lines to gas valves in heating, cooking, and water heating systems. Utilizing a screw machined brass construction, it provides a reliable, leak-proof seal without the need for an additional compression nut, streamlining the assembly process during field service. The unique breakaway design ensures that the fitting secures itself firmly around the 1/8-inch OD tubing once tightened, preventing common failures associated with over-torqueing or vibrations in HVACR control systems.
Key Benefits- Single-Piece Installation: Replaces the standard nut and ferrule combination, reducing part count and potential leak points.
- Precision Machined: Manufactured from high-grade brass to withstand the thermal stressors found in commercial cooking and residential heating applications.
- Mechanical Integrity: The breakaway mechanism ensures consistent clamping force on 1/8" tubing for gas-tight pilot lines.
- Universal Compatibility: Fits standard Robertshaw gas valves and various OEM pressure sensing and temperature control capillary tubes.
Is this ferrule compatible with aluminum or copper tubing?
Yes, the Robertshaw 4590-065 is designed to bite into and secure both aluminum and copper 1/8” OD tubing commonly used for pilot assemblies.
Do I need to carry a separate compression nut when using this part?
No, the breakaway design integrates the functionality of the nut, allowing the technician to thread the fitting directly into the valve body.
Can this be reused once the ferrule has broken away?
No, this is a one-time use component. Once the ferrule base breaks free to lock the tubing in place, a new 4590-065 is required for any future re-connections to ensure a safe seal.
