A MP-06-08 | 3/8" hose x 1/2" NPTF male pipe is a type of hydraulic fitting that consists of two parts: a hose fitting with a 3/8" inside diameter and a male pipe fitting with a 1/2" size and NPTF (National Pipe Taper Fuel) thread type. The NPTF thread has a tapered design that allows the fitting to create a seal as it is tightened into a matching female NPTF fitting, without the need for a sealing washer or O-ring. It is often used in conjunction with a matching female NPTF fitting and sealing tape or thread sealant to ensure a leak-free connection.
