912-08-04-BLK 1/2" to 1/4" NPT Reducer | Black Anodised

Speedflow 912-08-04-BLK | 1/2" to 1/4" NPT Reducer — Black Anodised

Step down a 1/2" NPT port to accept 1/4" NPT fittings, sensors, and adapters with the Speedflow 912-08-04-BLK — a precision-machined NPT reducer bushing in black hard anodised aluminium. A practical one-step reducer for builds where large 1/2" NPT ports on oil pans, filter housings, and high-flow engine components need to accept the more common 1/4" NPT thread standard used across a wide range of aftermarket fittings, sensors, and plumbing adapters.

Why Choose the Speedflow 912-08-04-BLK?

• Precision CNC machined aluminium — accurate 1/2" NPT male and 1/4" NPT female threads for a reliable, leak-free connection
• Black hard anodised finish — corrosion, heat, and fluid resistant for long-term reliability in demanding engine bay environments
• 1/2" NPT male to 1/4" NPT female — reduces a large 1/2" NPT port to accept the widely used 1/4" NPT thread standard
• One-step reduction — directly bridges 1/2" to 1/4" NPT without needing intermediate adapters
• Compact bushing design — minimal protrusion for tight engine bay installations
• Lightweight construction — negligible weight impact for race and performance builds

Ideal Applications

Reducing 1/2" NPT oil pan ports to accept 1/4" NPT fittings, adapting large filter housing ports to 1/4" NPT plumbing, fitting 1/4" NPT oil pressure sensors and temperature senders into 1/2" NPT engine ports, and any application requiring a 1/2" to 1/4" NPT thread reduction.
