American Grease Stick CFS-3B Brass Compression Sleeve 5/16 Inch Tube

The American Grease Stick CFS-3B is a brass compression sleeve designed for use with 5/16 inch tubing in low-pressure fluid transfer applications. This essential fitting component works in conjunction with compression nuts and fitting bodies to create secure, leak-free connections for air, oil, and water lines.

Key Features:

• Precision-engineered brass construction for durability and corrosion resistance
• Compatible with 5/16 inch copper, brass, and aluminum tubing
• Creates leak-free seal through wedging action between fitting body and nut
• Ideal for low-pressure applications including air lines, oil systems, and water connections
• Manufactured to strict quality standards for reliable performance

Installation: To install, slide the compression nut over the tubing first, followed by this compression sleeve. Insert the tubing into the fitting body and tighten the nut. As the nut is tightened, the sleeve wedges between the body and nut, compressing against the tubing to form a secure, leak-proof seal.

This fitting is commonly used in automotive, marine, industrial, and general maintenance applications where reliable fluid connections are required. Sold individually, one sleeve per package.
