AF C3249 Male O-Ring Boss To Male Pipe Adapter - 3/4-16 To 1/4 Pipe Thread

Hydraulic system folks, this AF C3249 adapter is one of those specialized fittings you need for specific connections. It's a male O-ring boss (that's the ORB side) to male pipe thread adapter, with the O-ring boss being 1/2 inch size with 3/4-16 threads and the pipe side being 1/4 inch with .540-18 threads. Made from plated steel, this fitting handles the pressures and demands of hydraulic systems without leaking or failing. The O-ring boss side creates that reliable seal with the included O-ring, while the pipe thread side connects to your standard pipe threaded components. It replaces Parker part number 8-1/4 F5OF-S and Weatherhead C3249X8X4, so if you're working with those systems, you know this is the right match. These adapters are crucial when you're connecting different types of components in hydraulic circuits - maybe converting from ORB flanges to pipe-threaded hoses or valves. The quality construction means it won't strip or cross-thread easily, and the plating helps resist corrosion in tough environments. Whether you're maintaining equipment, building custom hydraulic systems, or doing repairs, having the right adapters like this one makes the job so much smoother. Always use proper thread sealant on the pipe thread side and make sure the O-ring is properly seated on the boss side for leak-free performance.
