Steyr air pistol filling adapter is a critical component used to safely refill compressed air cylinders (rated for 200/300 bar) on competition models like the EVO 10, LP 10, LP 50, and Challenge series. It connects the air cylinder to a high-pressure source, such as a SCBA scuba tank, manual hand pump, or compressor.
Key Features and Variations Thread Types: Standard adapters usually feature a 1/8" BSPP female thread or a quick- disconnect (Foster) fitting, allowing them to hook up directly to standard fill lines.
Bleed Capability: High-quality aftermarket versions (like those from Best Fittings or Scuba Equipment Servicing Centre) are "through-drilled." This allows you to bleed the air charging system without unscrewing the reservoir under pressure, preventing premature thread wear
Model Specific: While there are universal adapters that fit most Steyr PCP pistols, you should ensure compatibility with either air pistols or air rifles
