912-04-02-BLK 1/4" to 1/8" NPT Reducer | Black Anodised

Speedflow 912-04-02-BLK | 1/4" to 1/8" NPT Reducer — Black Anodised

Adapt a 1/4" NPT female port down to a 1/8" NPT male fitting with the Speedflow 912-04-02-BLK — a precision-machined NPT reducer bushing in black hard anodised aluminium. One of the most commonly needed thread reducers in performance automotive plumbing, this fitting allows 1/8" NPT-threaded sensors, gauges, and fittings to be installed into larger 1/4" NPT ports cleanly and without thread sealant complications. An essential adapter for any workshop building oil, fuel, or coolant monitoring systems.

Why Choose the Speedflow 912-04-02-BLK?

• Precision CNC machined aluminium — accurate 1/4" 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
• 1/4" NPT male to 1/8" NPT female — reduces a 1/4" NPT port to accept 1/8" NPT male fittings and sensors
• Most common NPT reducer size — the go-to adapter when fitting 1/8" NPT sensors into 1/4" NPT ports on oil, fuel, and coolant systems
• 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 1/4" NPT engine ports, installing 1/8" NPT temperature senders into 1/4" NPT coolant ports, adapting 1/8" NPT fuel pressure gauges to 1/4" NPT fuel system ports, and any application requiring a 1/4" to 1/8" NPT thread reduction.
