Stainless Steel Quick Connect Fitting
This stainless steel quick connect fitting is a high-precision fluid pipeline connector designed for pneumatic systems, hydraulic equipment, automated production lines and fluid transmission workstations. Made of corrosion-resistant stainless steel and processed via precision CNC turning, it features external thread connection, hexagonal wrench positioning and multi-stage barb hose joint structure. It delivers leak-proof, stable fluid transmission connection for air pipes, liquid pipelines and equipment fluid circuits, ensuring reliable sealing and long service life in long-cycle industrial fluid transmission scenarios.
- Machining Process: Precision CNC turning, drilling, deburring, surface polishing optional
- Material: SUS304 Stainless Steel (SUS316L customizable for corrosive media)
- Accuracy: ±0.01 mm, ultra-precision version up to ±0.005 mm
- Surface Finish: Bright polished, matte finish optional
- Features: Excellent anti-corrosion, leak-tight sealing, easy installation, high pressure resistance
We specialize in custom CNC machining of stainless steel pipeline fittings. Our workshop is equipped with high-precision CNC lathes, turn-mill composite centers, internal & external deburring machines and full surface treatment facilities. With years of experience manufacturing quick connect fittings, pipe adapters and hose connectors, we can stably control core dimensional tolerances within ±0.01 mm. We provide one-stop services including drawing optimization, CNC turning, precision deburring, surface polishing and full finished-product inspection, serving clients engaged in pneumatic automation, hydraulic machinery, chemical fluid equipment and food processing industries.
Core Advantages
- Powerful Corrosion Resistance: SUS304 stainless steel raw material resists rust, oxidation and weak acid & alkali liquid erosion, suitable for wet, humid and chemical fluid working environments.
- Zero-Leak Sealing Performance: Precision CNC machined thread and barb structure perfectly match standard hoses and pipe nuts, effectively avoiding gas or liquid leakage under working pressure.
- Easy & Fast Assembly: Integrated hexagonal wrench surface for convenient tightening without slipping; stepped barb design locks rubber/plastic hoses tightly for quick plug-and-play installation.
- High Pressure Resistance & Durability: Integrated one-piece turning structure with no assembly gaps, capable of sustaining stable high fluid pressure, resisting cracking and deformation during long-term repeated disassembly.
- Fully Customizable Non-standard Sizes: Custom thread standards, thread diameters, barb outer diameters and overall lengths available to match all kinds of pneumatic and hydraulic pipeline layout requirements.
