The straight version of the -3 to female M10x1.0 hose end, machined from SUS303 stainless. Where the port has clear space in front of it, a straight fitting is the first choice: it is the shortest, lightest and least restrictive of the three body styles and adds no offset to your hose length calculation. It suits master cylinder outlets, rear axle unions and any run where the hose leaves the port in the direction it already wants to go. Confirm the port is M10x1.0 rather than M10x1.5, and that the male fitting’s seat form matches the female seat here, before you commit to building the hose.
