The Kleinn 1/8" F NPT compression fitting is made for connecting 1/4" O.D. tubing to a 1/8" female NPT port via a compression seal. It’s intended where a smaller threaded inlet must serve a standard 1/4" nylon line on onboard air systems. The fitting provides a straightforward, pressure‑rated transition between tubing and a 1/8" female NPT component.
