American Grease Stick CFS-4B Brass Compression Sleeve 3/8 Inch Tube

The American Grease Stick CFS-4B is a brass compression sleeve designed for 3/8 inch tubing applications. This precision-manufactured fitting component provides a reliable, leak-free connection when used with compression unions in low-pressure systems.

Key Features:

• Constructed from durable brass material for corrosion resistance
• Designed for 3/8 inch tube size applications
• Compatible with copper, brass, and aluminum tubing
• Creates leak-free connections through wedging action between fitting body and nut
• Ideal for low-pressure air, oil, and water applications
• Manufactured to strict AGS quality standards

Installation: Place the compression nut over the tubing first, followed by this sleeve. Insert the tube into the fitting body and tighten. The sleeve's wedging action between the body and nut creates a secure, leak-free seal.

This compression sleeve is sold individually (1 per bag) and is part of the comprehensive American Grease Stick line of brass and steel fittings for professional and industrial fluid handling applications.
