Just purchased a grapple that has 1/2 #8 fittings on the hoses. I plan on using the rear remotes on the tractor to run the grapple claw. The female quick couplers on the tractor remotes are pioneer 4050 3p (3/8 poppet style) So I plan to run hoses from the rear to the front. The trick is when I get to the front. Does anyone know if you can you mate a 4050 3p (3/8) female to the 4050 4P (1/2) male. I was told that the actual coupler i.d and the nipple i.d. were the same size??? My goal would be to have all the stuff consistant Any advice would be great. Mike
