Features & Benefits

• Industry‑leading flow rates；
• Anti‑leak spring‑loaded poppets instantly stop gas flow upon disconnection, greatly enhancing safety and reducing debris ingress into the system；
• Specifically designed for high‑pressure CNG service；
• Stainless steel construction provides corrosion and wear resistance；
• Hardened segment connection style increases gripping surface area, significantly reducing wear on male couplings；
• Designed to be coupled/uncoupled only at atmospheric pressure (0 psi gauge), making accidental disconnection very difficult and improving device safety；
• Integrated lock‑in‑place sleeve ensures correct coupling engagement；
• A green ring is visible on the female half only when properly coupled, providing visual confirmation of correct mating with a male half before pressurization；
• Male coupler includes a recommended dust cap；
• Service kits are readily available and easy to install；
