Professional High-Pressure Transfer Adapter – G5/8 to 8mm Quick Coupler with Gauge

This compact and lightweight transfer adapter is designed for safely moving high-pressure air from a main cylinder (e.g., carbon fiber tank, DIN tank) to a smaller device or secondary bottle. Made from **7075 aircraft-grade aluminum**, it offers exceptional strength-to-weight ratio – strong enough for 300 BAR (4500 PSI), yet light enough for portable use.

Perfect for diving, PCP air rifles, HPA systems, and field maintenance, this adapter ensures precise control, real-time pressure monitoring, and fast depressurization.
