Certified Quality

Independent Verification, Market by Market

Our fittings are qualified for the markets where they work hardest — from EAEU certification to classification-society type approval.

EAC Certified

Eurasian Economic Union conformity — one certificate covers Russia, Kazakhstan, Belarus and the wider EAEU.

Lloyd's Register

Type-tested by Lloyd's Register for marine and offshore instrumentation service.

ISO 9001

Manufactured under an ISO 9001 quality management system with full material traceability.

Applications

Where Our Components Work

From oil & gas instrumentation to chemical process skids and hydraulic control systems.

Oil & Gas

Instrumentation tubing for wellhead, gathering and processing systems.

Chemical Process

Corrosion-resistant connections for analyzers and sampling systems.

Hydraulic Control

High-pressure fittings for control panels and actuation circuits.

Industrial Automation

Compact valve and fitting packages for skid-mounted instrumentation.

Manufacturing

Precision Machined. Tested. Traceable.

Every fitting is machined from certified 316 stainless steel barstock (GOST 03X17H14M2) and dimensionally controlled to meet international instrumentation specifications — interchangeable with leading global fitting brands.

Two-piece ferrule design, precision sealing surfaces and no-weld assembly mean faster installation, fewer leak paths and lower lifecycle cost.

100% dimensional interchangeability with international standards
Leak-free performance under vibration and pressure shock
Full material certification and batch traceability
