Giilayky Fill Station Charging Adaptor is sports refill equipment that lets divers and PCP owners connect tanks for controlled high-pressure refills. Peace of mind while topping up keeps cylinders ready for diving and shooting sessions. Is the adaptor the right addition to a home refill setup?

⚡ At a Glance
  • Connection Compatibility: DIN G5/8inch fitting fits both 232bar and 300bar diving cylinders
  • Best for: PCP refilling enthusiasts and divers who use DIN-equipped cylinders
  • Not ideal for: Owners without a matching male plug or a 1/8 inch BSPP male charging probe

Supplied as a compact refill adaptor with hose and bleed valve for hands-on topping up. Designed to link scuba DIN tanks to PCP refill setups.


Clear pressure feedback - with a compact sealed 40MPa/6000psi gauge

A sealed 40MPa/6000psi gauge is supplied with the kit, mounted to the fill hose to register pressure during refills. The sealed construction helps keep the gauge stable under high-pressure conditions.

On-the-spot readings make it straightforward to monitor tank pressure while topping up, reducing guesswork and helping avoid overfill.

Wide tank compatibility - thanks to a DIN G5/8inch fitting

The DIN G5/8inch fitting is compatible with both 232bar and 300bar diving cylinders, allowing direct connection to commonly used scuba tanks. The hose ends in a stainless quick coupler socket for secure hookups.

One connection handles the most common high-pressure cylinders used by divers and PCP users, simplifying the refill process across equipment types.

Controlled refills - with an integrated bleed valve and quick coupler

A bleed valve is included to release residual pressure safely during disconnect, while the stainless quick coupler socket allows fast, secure attachment and removal of the hose. The hose assembly completes the flow path between source tank and receiving cylinder.

Safe, manageable fills are possible even for home setups, since pressure can be bled off deliberately and connections are quick to make and break.
