High-Pressure Thread-Lock Quick-DisconnectHose Couplings for Hydraulic Fluid. Use these couplings at pressures up to 10, 000 psi. The plug and socket thread together to form a stronger connection than other quick-disconnect couplings. They are compatible with High-Pressure Thread-Lock-shape plugs and sockets.

We have compiled a simple step-by-step guide to help you identify your thread type. In addition, we'll cover some of the most common port thread types including NPT/NPTF, BSPP (also known as G), BSPT, PT, Metric (M) and SAE. You'll need a couple tools on hand to make the process easier, but a straight steel ruler may work as well.

For example, G threads are not compatible NPT threads because of their differing angles, shapes, and thread Metric Thread Type Chart.

Metric Thread Tolerances. The tolerances TD for internal threads and Td for external threads is derived from the class. The approximate tolerances can be calculated according to the below

Whitworth's new standard specified a 55° thread angle and a thread depth of 0.640327p and a radius of 0.137329p. Where p is the pitch. The thread pitch increases with the diameter in steps specified on a chart. The Whitworth thread system was later to be adopted as a British Standard to become British Standard Whitworth (BSW).
