Versil Flare Flareless Tube Ferrule For 0.50 Inch Tube

Description & Features

Designed for precision and durability the Danfoss / Eaton FF9605 Series Steel Adapters Sleeve is optimal for industry-specific applications involving 0.50-inch tubes. This Versil Flareless Tube Ferrule ensures a secure fit and reliable performance crucial for maintaining system integrity.

Constructed by Danfoss Power Solutions (II LLC Aeroquip) this fitting stands out for its robust engineering and reusability withstanding a minimum of 10 reassemblies. The initial assembly process involves sliding the ferrule and nut onto the tube ensuring lubrication with a heavy-duty lubricant like Aeroquip 222070 lube for optimal mating. Tightening and proper marking ensure alignment and effective sealing.

To enhance installation integrity it's crucial to deburr all cut tubes both internally and externally and ensure they are cut squarely within a tolerance of +/- 1deg;. Maximum tubing hardness for compatibility is Rockwell B65 excluding stainless steel tubing. This fitting is tailored for rigorous applications meeting the highest standards.

Question by: Ronnie T on Dec 15, 2025, 11:31 AM
Got a half-inch tube I'm trying to fit this ferrule on, just want to make sure I'm not mixing up OD and ID before I order. This is for the outside diameter, right?
Answer by: Customer Support on Dec 17, 2025, 6:01 AM
Correct, the 0.50 inch dimension refers to the tube's outside diameter. The B attribute on this part confirms that 0.50 inch OD tube is what this ferrule is sized for. As long as your tube measures a half inch on the outside, you're working with the right part.
