· Product Overview
Introducing the YITECH Precision Push-to-Connect Pneumatic Quick-Coupler Pair — a CNC-machined, self-sealing male/female coupling system engineered for tool-free, bubble-tight fluid/gas transfer in industrial automation, medical devices, and lab instrumentation.
Each pair delivers:
- Solid 316L stainless steel construction (standard); optional: 304 SS, 6061-T6 aluminum, or titanium
- Push-to-connect (PTC) male end: Accepts standard polyurethane (PU) or nylon tubing (Ø6 mm, Ø8 mm, or custom OD) — no ferrules, no tools required
- Threaded female end: G1/8"BSPP (parallel) or 1/4"-18 NPT (tapered) — for secure panel mounting
- Valved design: Internal spring-loaded ball/pin seals automatically close upon disconnection — preventing air loss, contamination, and pressure drop
- Hexagonal body (10 mm AF) — enables secure wrench tightening without slippage
- Mirror-polished sealing surfaces (Ra ≤ 0.2 μm) — ensures leak-tight performance at up to 10 bar (145 PSI)
Unlike plastic or low-grade brass QD couplers (prone to cracking, swelling, or valve failure after 5,000 cycles), our monolithic couplers withstand >100,000 connect/disconnect cycles with zero leakage — verified per ISO 15877 and ISO 4414.
Ideal for designers building collaborative robots, dental units, lab autosamplers, or portable medical devices where speed, reliability, and sterility are mission-critical.
