The bolt’s M12 x 1.25 threads and the upper 1\/8\" NPT port provide a secure mechanical connection while allowing pressure-sensing or auxiliary tapping through the NPT opening. The kit ships with two crush washers to ensure a leak-resistant seal when installed.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this banjo bolt work with common fuel and oil systems?\u003c\/h3\u003e\n\u003cp\u003eThe banjo bolt passes fluid through a hollow center and radiating holes into the joined fitting, creating a low-profile, leak-minimizing connection ideal for tight spaces. The included 1\/8\" NPT upper port accepts sensors, bleeders, or small tubing for additional plumbing or pressure monitoring. Installation is straightforward and uses standard 12mm banjo adapter geometry.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHollow M12 bolt body routes fluid through the banjo fitting\u003c\/li\u003e\n  \u003cli\u003eUpper 1\/8\" NPT port allows tapping for sensors or auxiliary lines\u003c\/li\u003e\n  \u003cli\u003eTwo crush washers included to ensure a sealed joint\u003c\/li\u003e\n  \u003cli\u003eWorks with fuel, oil, coolant, water and compressed air\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the exact thread and compatibility specifications?\u003c\/h3\u003e\n\u003cp\u003eThe bolt uses an M12 x 1.25 external thread, matching most 12mm banjo adapters and fittings.
