About Measuring Fittings

Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Compression Orifice Valves

Compression fittings bite down on the outside of hard metal tubing for a secure connection. Also known as flow restrictors and precision orifice valves, these orifices are used to throttle, vent, bleed, or regulate the flow of liquids and gases.
