819-04-BLK -4 Tube Sleeve | Black Anodised

Speedflow 819-04-BLK | -4 Tube Sleeve — Black Anodised

The Speedflow 819-04-BLK is the matching tube sleeve for the SF818-04-BLK -4 AN tube nut, completing the compression-style hard line adapter system. Together, the sleeve and tube nut convert steel or aluminium hard line tubing to standard -4 AN fittings — cleanly and without welding or brazing. Flare your tubing to 37°, slide the sleeve over the tube end, and secure with the matching tube nut for a professional, leak-free hard line connection suited to brake, fuel, oil, and clutch line applications.

Why Choose the Speedflow 819-04-BLK?

• Compression tube sleeve — works in conjunction with the SF818-04-BLK tube nut to create a complete -4 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
• -4 AN sizing — one of the most commonly used AN hard line sizes across brake, fuel, oil, and hydraulic clutch applications
• Lightweight construction — negligible weight impact for race and performance builds
• Sold individually — order the exact quantity needed for your build

Ideal Applications

Brake hard line fabrication, hydraulic clutch line connections, fuel hard line conversions, oil hard line plumbing, and any -4 AN hard line circuit requiring a compression tube sleeve.

Important Note

Must be used with the matching SF818-04-BLK -4 AN tube nut and a 37° flaring tool. The tube must be flared before fitting the sleeve and nut. Sleeve is for hard line use only — not compatible with braided hose.
