Haltech 1/4in Stainless Compression 1/8in NPT Thread Fitting Kit w/Nut & Ferrule

This kit from Haltech gives you a 1/4 inch stainless steel compression fitting, complete with a nut and ferrule. It's designed to connect to a 1/8 inch NPT threaded port, offering a solid connection for your fuel or oil lines. Stainless steel is a good choice here because it holds up well against corrosion and won't degrade over time, even with different fluids running through it.

When you're setting up custom fuel rails, oil pressure sensors, or any other line that needs a reliable connection to a threaded port, fittings like these are essential. The compression style means you get a tight seal by squeezing the ferrule onto the tubing, and the nut tightens it all down. It's a straightforward way to ensure your lines don't leak under pressure.
