YING ZEARK FLOW is a manufacturer of 316 stainless steel instrumentation tube fittings, forged instrument valves and vacuum components — built around one idea: a connection that holds under pressure, vibration and time.
We machine our fittings from certified 316 stainless steel barstock (GOST 03X17H14M2) — the same material family specified across oil & gas, chemical and process instrumentation worldwide. Every lot is dimensionally inspected and traced from barstock to finished part.
Our two-piece ferrule fittings are designed for leak-free service under vibration and pressure shock, and are dimensionally interchangeable with international instrumentation fitting specifications — so customers can switch suppliers without re-engineering their systems.
We also supply industrial process valves — ball valves, butterfly valves and special-service valves — on a project basis.
Compression fittings pressure-rated to 6000 psig (413 bar) for demanding instrument service.
Full service range from −54 °C to 648 °C without compromising the seal.
Complete size coverage from 1/8″ to 2″ (6 mm to 50 mm) across the product range.
Because the specification matches, the certificates are in place, and the seal holds. Our fittings are built to international instrumentation standards, qualified for the EAEU market, and backed by independent type approval — without the premium price of legacy brands.
