Safety Coupler 1/4″ Industrial Socket NPT Female

Infinity Safety Quick Coupler: 1/4″ Industrial Socket (Female NPT)

The Safer Standard for Hard-Piped Connections

Bring advanced safety technology to your air drops with the Infinity Safety Quick Coupler (1/4″ Industrial – Female NPT). This high-performance coupler is designed to screw directly onto male-threaded pipe nipples or hose ends, transforming a standard connection point into a zero-recoil safety outlet.

Traditional couplers can be hazardous; disconnecting a tool under pressure often causes the plug to eject violently (“hose whip”), creating a risk of injury and a loud, startling noise. The Infinity Safety Coupler eliminates this danger using a patented Two-Step Disconnection System that vents trapped pressure before the tool is released.

Two-Step Release Technology

1. Step 1 (Vent): Press the button once. The supply valve closes, and the air trapped in the tool or downstream hose is vented safely and silently. The plug remains locked in the socket.
2. Step 2 (Release): Press the button a second time. The plug is released with zero pressure behind it, allowing it to slide out smoothly without kickback.

Key Features & Benefits

• Female NPT Connection: Features a sturdy Female NPT thread, making it the perfect choice for installing onto the end of male-threaded pipe drops, rigid steel nipples, or male hose fittings.
• OSHA Compliance: Meets safety standards for compressed air devices by preventing projectile disconnection. It protects your employees from impact injuries and reduces sudden noise spikes in the facility.
• Industrial Standard (M-Style): Fully compatible with standard 1/4″ Industrial Interchange plugs (MIL-C-4109 / ISO 6150 B). You can upgrade your safety without replacing every plug in your shop.
• Scratch-Free Composite Body: Constructed from a high-impact technopolymer. Unlike heavy metal couplers, this lightweight body won’t dent or scratch delicate surfaces (like vehicle paint or finished products) if dropped or dragged.
• Push-Button Ergonomics: The intuitive push-button mechanism is easy to operate with one hand, even while wearing heavy work gloves.
