With the soul of forged steel, we forge the ultimate sealing art of zero leakage through 10,000 pulses.

Core Product Matrix

A Four-Dimensional Performance Revolution

Revolutionizing Pulse Fatigue Life

After 100,000 pulse tests (0→150 MPa):

◉ Sealing surface indentation <3μm (ISO 8434-1 standard allows 15μm)

◉ Thread root stress <30% σs** (industry average >50%)

Micron-level sealing surface control

Generation failed, ask another way

▸ 24° cone roundness ≤0.005mm

▸ Flat seal end runout ≤0.01mm

Corrosion Terminator

Intelligent anti-loosening design

◼ Triple locking structure: Serrated locking ring + deformation preload groove + torque indicator groove

◼ Vibration table tested: 100,000 cycles with zero loosening at 30Hz/5mm amplitude

Extreme Performance Benchmark:

🔩 150MPa Ultra-High-Pressure Threading: M42×2 threads withstand 9800N·m of torque

🛢️ Deep-Sea Adapter: 6000m pressure resistance with zero leakage (equivalent to 60MPa hydrostatic pressure)

⚡ Explosion-Proof Welding Joint: Passes 20kJ electrostatic discharge test (IEC 60079 standard)

Quality Control: Exceeds aerospace standards
