901-06 Aluminium washer 9/16"-14mm (EACH)

Speedflow 901-06 | 9/16" (14mm) Aluminium Sealing Washer — Sold Individually

The Speedflow 901-06 is a precision-made 9/16" (14mm) aluminium sealing washer — an essential consumable for motorsport and performance automotive builds running banjo bolt fittings, drain plugs, and ported components with 9/16" / M14 fasteners. Soft aluminium construction compresses on tightening to conform to mating surfaces, creating a clean, reliable, leak-free seal without thread sealant or PTFE tape. The 9/16" / 14mm size is commonly found across oil system drain plugs, larger banjo bolt applications, and engine porting on performance and motorsport engines.

Why Choose the Speedflow 901-06?

• Soft aluminium construction — compresses to conform to mating surfaces for a positive, leak-free crush seal
• 9/16" (14mm) internal diameter — suits 9/16" / M14 banjo bolts, drain plugs, and port fittings on engines, gearboxes, and oil systems
• No sealant required — aluminium crush washers seal on compression alone for a clean, professional result
• Single-use design — should be replaced each time the fitting is removed to ensure a fresh, reliable seal
• Ultralight at just 1g — negligible weight for a critical sealing component
• Sold individually — order the exact quantity needed for your build or service
