This is a handy adapter that connects a 1/4-inch SAE 45-degree female flare fitting to a 1/8-inch NPT male pipe thread. It's brand new, unused, and comes in its original packaging (manufacturer packaging likely). Made from rust-resistant material (typically brass), it's versatile and suitable for LP gas, LNG, air, water, hydraulic systems, brakes, power steering, and more. Great for automotive, HVAC, refrigeration, and industrial uses. The model is SAE45-33-4A, and it works with copper tube, flared tube, and welded steel hydraulic lines. It's unbranded/generic but made in Taiwan, which often means decent quality for fittings like this. UPC doesn't apply. If you're plumbing a fuel line, setting up a propane system, or working on hydraulic connections and need to transition between these two common fitting types, this adapter does the job. Simple, solid, and new in package. Always check your thread sizes and application to make sure it's the right fit.
