About Us

A Fittings Manufacturer That Treats a Seal as Engineering

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.

Precision Machined. Certified. Traceable.

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.

  • 316 stainless steel, instrumentation grade, certified material
  • Double ferrule design — leak-free under vibration and shock
  • No-weld assembly for faster, cleaner installation
  • 100% dimensional interchangeability with international standards
  • EAC · Lloyd's Register · ISO 9001

We also supply industrial process valves — ball valves, butterfly valves and special-service valves — on a project basis.
