Threaded Flow Control Orifices
Connect these orifices to threaded pipe, or insert them into threaded holes. Also known as flow restrictors and precision orifice valves, they are used to throttle, vent, bleed, or regulate the flow of liquids and gases.
316 stainless steel orifices have better corrosion resistance than 303 stainless steel orifices.
- For Use With: Air, Argon, Carbon Dioxide, Helium, Neon, Nitrogen, Oil, Water, Xenon
- Max. Pressure: 4,000 psi @ 70° F
