WebNPT threads in that NPT threads are designed for mechanical or low-pressure air or fluid applications. Visually, the two look identical. However, the thread forms are different. … WebPipe thread sizes do not refer to any physical dimension. The outside diameter of each pipe fitting must be measured and compared to the table for size identi-fication. For example, a 1” MPT pipe thread has an outside diameter of 1.315” NPT Size Thread Diameter OD of MPT (ID of FPT will be slightly less than this.) 1/8” 0.405” 1/4” 0. ...

Insert the barbed end of the fitting into hose, then position the interlocking clamp over the hose and bolt into place. The clamp firmly grips your hose as it locks into the ring of the barbed end, creating a leak-tight seal.
