819-03-BLK -3 Tube Sleeve | Black Anodised

Speedflow 819-03-BLK | -3 Tube Sleeve — Black Anodised

The Speedflow 819-03-BLK is the matching tube sleeve for the SF818-03-BLK -3 AN tube nut, completing the compression-style hard line adapter system. Used together, the tube sleeve and tube nut convert steel or aluminium hard line tubing to standard -3 AN fittings — no welding or brazing required. Simply flare your tubing to 37°, slide the sleeve over the tube, and secure with the matching tube nut for a clean, leak-free hard line connection.

Why Choose the Speedflow 819-03-BLK?

• Compression tube sleeve — works in conjunction with the SF818-03-BLK tube nut to create a complete AN hard line adapter
• 37° JIC/AN flare compatible — designed for use with tubing flared to the standard 37° AN flare angle
• Black hard anodised aluminium — corrosion and fluid resistant with a clean, professional finish
• -3 AN sizing — suits the smallest AN hard line size, commonly used for brake and hydraulic clutch lines
• Ultralight at just 1g — negligible weight impact for brake and clutch line applications
• Sold individually — order the exact quantity needed for your build

Ideal Applications

Brake hard line fabrication, hydraulic clutch line connections, and any -3 AN hard line plumbing circuit requiring a compression tube sleeve.

Important Note

Must be used with the matching SF818-03-BLK -3 AN tube nut and a 37° flaring tool. The tube must be flared before fitting the sleeve and nut. Sleeve is not compatible with braided hose — for hard line use only.
