Size of threads are on an inflation needle?

The size of threads on an inflation needle typically refers to the standard size of the threaded portion that screws into a pump or gauge. Most commonly, inflation needles have a thread size of 1/4 inch NPT (National Pipe Thread), which is a standard size used in many inflating devices. It's essential to ensure compatibility between the inflation needle and the equipment to avoid leaks or improper fitting. Always check the specifications of your equipment for the correct thread size.
