General Installation and Safety Tip: Before connecting, verify both system ports and adapter threads are clean and undamaged. Hand-tighten firmly until snug—do not use tools that could over-torque and damage threads. When disconnecting, allow the auto-shutoff to engage fully before removing. Store adapters in a clean, dry case to protect threads and sealing surfaces from debris.Material: Brass Color:Gold (As Pictures Show)Types:Male 5/16 x F1/4 SAEQuantity: 6pcsNote:1.

• Reverse Thread Safety Design: The specialized thread orientation physically prevents connection to incompatible refrigerant systems, eliminating accidental cross-contamination and ensuring correct pairing with equipment for safe operation
• High-Purity Brass Material Construction: Machined from premium brass stock that resists corrosion and wear, each adapter maintains structural integrity through repeated connections and disconnections in demanding service environments
• Built-in Automatic Shut-Off Valve: An integrated check valve closes instantly when disconnected, trapping residual refrigerant within the hose to prevent finger burns from escaping gas and minimizing refrigerant loss during system servicing
• Precision-Machined Leak-Proof Threads: The finely cut thread surfaces create a tight metal-to-metal seal when engaged, preventing refrigerant escape at connection points and maintaining system pressure for efficient cooling performance
• Knurled Grip Surface for Easy Handling: The textured exterior provides positive finger traction even when wearing work gloves, enabling secure manual tightening and loosening without slipping or requiring additional tools
