AirForce Universal DIN Refill Assembly with Quick Disconnect – PCP Airgun Charging Adapter

The AirForce Universal DIN Refill Assembly with Quick Disconnect is a purpose-built accessory that allows you to connect a high-pressure scuba tank (DIN valve) to your PCP (precharged pneumatic) air rifle’s fill system using a quick-disconnect fitting. This setup significantly simplifies the process of topping up your rifle’s air supply compared with hand pumps, letting you fill quickly, reliably, and with minimal effort.

Key Features

DIN Valve Connection:
• Designed to screw onto a standard DIN valve on scuba tanks or high-pressure storage bottles, creating a secure high-pressure connection for PCP rifles. This makes it easier to use commonly available tanks for refilling your airgun.

Quick Disconnect Fitting:
• The assembly includes a paintball-style quick disconnect fitting that mates with your airgun’s fill nipple for fast, tool-free attachment and detachment during each refill.

Broad Compatibility:
• Works with rifles and external tanks that use the standard quick disconnect/paintball fill nipples, including many AirForce models and other PCP platforms.

High-Pressure Usage:
• Built to handle the high pressures associated with scuba and carbon-fibre supply bottles (typically up to ~300 bar / 4,350 psi), providing a robust solution that’s much easier than manual pumping.

Durable Construction:
• Durable metal fittings and robust quick-disconnect components are engineered for repeated use under demanding high-pressure conditions typical of PCP refilling.

Technical Specifications

Note: Always verify the rated fill pressure and compatibility with your specific airgun and high-pressure supply before use.

Performance & Practical Use

This Universal DIN Refill Assembly makes refilling your PCP air rifle much faster and more effortless than using a manual hand pump alone. By tapping into a scuba tank or other high-pressure air source, you can quickly bring your rifle’s reservoir up to working pressure, significantly reducing time and physical effort. The quick-disconnect design means you can attach and detach the airgun with minimal fuss — ideal for multiple fills during range sessions or field use.

Many shooters find this approach far more convenient than hand pumping, particularly if they fire frequently or use multiple PCP airguns. In field scenarios or on extended outings, having this adapter lets you leverage a high-pressure tank safely and efficiently without needing extra tools or connectors.

Best Suited For:

✔ Shooters with PCP airguns that use standard quick-disconnect fill nipples
✔ Users who fill from scuba tanks or high-pressure air bottles
✔ Target shooters and hunters who want faster refill cycles
✔ Anyone upgrading from hand pump fills to a more efficient setup

User Tips

Check Compatibility:
Before use, make sure your PCP airgun’s fill nipple matches the quick-disconnect type on this assembly — most modern PCP rifles use the standard paintball-style fitting.

Use Proper Pressure Sources:
Only connect to certified scuba tanks or high-pressure air bottles rated for PCP filling (typically up to ~300 bar / 4,350 psi). This reduces safety risk and protects your rifle’s air reservoir.

Bleed Safely:
After filling, always slowly bleed residual pressure from the fill assembly before disconnecting to avoid sudden air release.

Store Dry and Clean:
After use, wipe down the quick disconnect and connections to prevent dirt or debris from entering your air system.
