- Made from high-strength aluminum alloy for a balance of durability and light weight — resists corrosion while minimizing added weight during transport and use. - 8 mm / 0.31 inch filling nipple with quick-disconnect design for fast separation and a secure tank connection — simplifies hookups and reduces time on the fill station. - Built-in pressure gauge provides accurate pressure readings during refilling so you can monitor tank pressure in real time and avoid under- or overfilling. - Portable, compact construction that ensures easy installation and removal — designed for quick field use and simple handling in busy shops or on-site servicing. - Function: a dive refill adapter that enables safe, controlled transfer of gas into dive tanks with clear pressure feedback and reliable mechanical connection. - Compatibility: intended for tanks and fill systems that use an 8 mm / 0.31 in filling nipple and standard refill procedures; suitable for professional and recreational refill setups. - Performance benefits: reduces refill time, improves safety through accurate pressure monitoring, and withstands repeated use thanks to rugged aluminum construction. Typical use scenarios - Scuba shop or service center: speed up cylinder refilling with a quick-disconnect nipple and monitor pressure on every fill. - On-site tank servicing or dive boat operations: lightweight and portable adapter makes installations and removals faster and less cumbersome. - Training and rental operations: consistent, measurable refills using the integrated gauge to ensure tanks are filled to the correct pressure for customer safety.
