8mm Scuba Adapter - Large To Small Bottle Converter For Diving (0.5L/1.0L, Quick Connect, 6061 Aluminum)

Divers, lighten your load! This clever 8mm scuba adapter lets you transfer oxygen or other gases from a large, heavy scuba tank into a compact, portable 0.5L or 1.0L bottle. It's perfect for short dives, backup gas, or surface-supplied diving setups where you don't want to haul a full-sized tank around.

The adapter is machined from high-strength Aviation Aluminum 6061 and features a reliable ball-lock quick-connect mechanism on the 8mm female end. This ensures a secure, leak-free seal even under pressure. The large, ergonomic spiral knob is designed to be easily operated with one hand, even while wearing thick dive gloves.

It includes a pressure relief feature – when you unscrew the knob after filling, it automatically vents any excess gas safely. Weighing only about 265g (9.3oz), it adds minimal bulk to your gear bag. The black anodized finish resists corrosion from saltwater.

This is commercial-grade equipment, proven in over 2000 dive center installations and built to exceed standards like EN250. It's compatible with about 90% of bottle valves on the market. A must-have tool for recreational and technical divers looking for efficiency and safety.
