912-08-02-BLK 1/2" to 1/8" NPT Reducer | Black Anodised

Speedflow 912-08-02-BLK | 1/2" to 1/8" NPT Reducer — Black Anodised

Fit a 1/8" NPT sensor, gauge, or fitting into a large 1/2" NPT port with the Speedflow 912-08-02-BLK — a precision-machined NPT reducer bushing in black hard anodised aluminium. This larger reducer bridges the significant size difference between 1/2" NPT ports — commonly found on oil pans, large filter housings, and high-flow engine components — and the smaller 1/8" NPT thread standard used by the majority of aftermarket pressure and temperature sensors. An essential adapter for any build where large NPT ports need to accept standard sensor hardware.

Why Choose the Speedflow 912-08-02-BLK?

• Precision CNC machined aluminium — accurate 1/2" NPT male and 1/8" 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 1/8" NPT female — reduces a large 1/2" NPT port to accept standard 1/8" NPT sensors and fittings
• Bridges a large size gap — purpose-built for applications where 1/2" NPT ports need to accept the smaller 1/8" NPT sensor thread standard
• Compact bushing design — minimal protrusion for tight engine bay installations
• Lightweight construction — negligible weight impact for race and performance builds

Ideal Applications

Fitting 1/8" NPT oil pressure sensors into 1/2" NPT oil pan or filter housing ports, installing 1/8" NPT temperature senders into large 1/2" NPT coolant ports, adapting standard sensor hardware to large-bore NPT ports on high-flow oil and fuel system components, and any application requiring a 1/2" to 1/8" NPT thread reduction.
