FMSI Fittings C4-100 1/4" Silver Zinc Hydraulic Tubing Coil 100 Foot

The FMSI Fittings C4-100 is a 100-foot coil of 1/4" O.D. silver zinc hydraulic tubing designed for brake, fuel, transmission, and oil cooler line applications. This professional-grade tubing features double-walled steel construction with no open seams, ensuring maximum strength and durability for critical hydraulic systems.

Key Features:

• Double-walled steel tubing construction with copper coating applied prior to rolling
• Silver zinc dichromate plating protects against road abrasion and corrosive chemicals
• Double annealed for improved workability, easy bending and flaring
• 0.028" wall thickness meets or exceeds OE specifications for brake line tubing
• Zinc plating thickness specification ≥ 13μm (manufactured to 13.3-13.8μm)
• 1/4" outside diameter suitable for domestic and import applications
• 100-foot coil length provides ample material for multiple repair jobs or custom fabrication

This tubing is ideal for professional technicians and experienced DIYers who need reliable, corrosion-resistant hydraulic line material for vehicle brake systems, fuel lines, transmission cooler lines, and oil cooler applications. The double annealing process makes the tubing easier to work with using standard bending and flaring tools.
