Refill Adapters

The SMACO S-Series Refill Adapters make it easy to transfer high-pressure air from a larger donor tank into your smaller mini-scuba or PCP cylinder. Each adapter is built with precision-machined aluminum components, a smooth-turn control valve, and an 8mm quick connector for secure filling. With YOKE, DIN, and compressor-direct options, the S-Series lets you choose the right setup for fast, safe refills across a wide range of cylinder sizes. YOKE, DIN, or compressor-direct compatibility Optional pressure gauge for real-time monitoring Optional dump valve for controlled pressure release Hose options for flexibility and fast filling Supports cylinders from 0.25L to 4.0L (model-dependent) Durable aluminum alloy construction
