Speedflow 814-16-BLK | -16 Hex O-Ring Port Plug — Black Anodised

When you need to seal a large-bore -16 AN port cleanly and permanently, the Speedflow 814-16-BLK is the professional's choice. Precision machined from high-grade aluminium and finished in a durable black hard anodise, this hex o-ring port plug is built for the demands of serious motorsport and high-performance automotive builds — where a weeping port plug simply isn't an option.

Why Choose the Speedflow 814-16-BLK?

• Precision CNC machined aluminium — tight tolerances ensure consistent thread engagement and a positive o-ring seal every time
• Black hard anodised finish — resists heat, corrosion, and fluid exposure in even the harshest engine bay environments
• -16 AN / ORB (O-Ring Boss) thread — designed for large-bore -16 ORB ports on high-flow oil, fuel, and coolant system components
• Hex drive — fits a standard spanner or socket for fast, tool-friendly installation and removal
• O-ring included — ready to install straight away with no additional hardware required
• Large port coverage — purpose-built for blanking high-volume flow paths on tanks, coolers, and reservoirs during builds or system changes

Ideal Applications

High-flow dry-sump oil tanks, large-capacity oil coolers, remote filter housings, fuel surge tanks, transmission coolers, power steering reservoirs, and any performance component with unused -16 ORB ports.
