Male Straight Push Lock 1/16in NPT to 1/4in Tube

The Male Straight Push Lock 1/16in NPT to 1/4in Tube adapter by VIBRANT PERFORMANCE is a critical fluid transfer fitting for any serious engine builder or custom automotive project. Whether you're routing fuel, boost reference lines, or cooling system bypasses in a tight engine bay, this adapter bridges the gap between metric and imperial pneumatic standards. Designed for builders who demand reliability under pressure, this push-lock connector eliminates the guesswork of mismatched port sizes and prevents costly leaks in high-vibration environments.

This straight push-lock fitting features a 1/16-inch NPT (National Pipe Thread) male port on one end and a 1/4-inch push-to-connect tube inlet on the other, allowing you to integrate metric vacuum and pressure lines into NPT-threaded ports without additional adapters or reducers. The push-lock mechanism—a time-tested design in performance plumbing—grips the tube securely and seals without thread sealant, reducing assembly time and the risk of contamination in precision fuel and coolant systems. VIBRANT PERFORMANCE's reputation for aerospace-grade fittings ensures minimal pressure drop and consistent performance whether you're running 5 psi vacuum or 80 psi boost reference.

Install this adapter wherever your custom turbo setup, standalone ECU, or aftermarket fuel system requires a seamless transition between 1/4-inch silicone or nylon tubing and NPT-threaded bosses on manifolds, intercooler tanks, or catch cans. Mechanics and fabricators working on LS swaps, rotary conversions, or fuel cell installations will appreciate the versatility—it solves port mismatch problems without reducing flow or adding bulk. Tighten the NPT end into your port, push the tube firmly home until you hear or feel the lock engage, and move on to the next line with confidence.
