Got a hydraulic line running NPT on one end and the block port is SAE O-ring boss. This adapter gonna bridge that gap straight without any offset?
Question by: Lance W on Aug 13, 2025, 1:55 PM
That's exactly what this fitting is built for. One end is 3/4-14 female NPT and the other is 1-5/8-12 male SAE O-Ring Boss, so it connects those two thread types in a straight inline configuration with no angle or offset. The O-ring boss end uses a straight thread with an O-ring seal, which gives you a much tighter, leak-resistant connection at the port compared to a tapered thread seal alone. Steel construction holds up well in demanding fluid handling setups.
