Installation & Usage Guidelines
- Hose Preparation: Cut hose squarely using a sharp blade. Ensure the internal diameter matches 12.7mm for optimal fit.
- Tailpiece Installation: Push hose firmly onto the barbed tailpiece until it reaches the shoulder. For added security, use a hose clamp rated for pneumatic applications.
- Thread Connection: Apply PTFE tape or thread sealant to the 1/2" BSP male thread of your air line. Hand-tighten the coupling, then use a spanner to achieve a secure seal (typically 1-2 turns past hand-tight).
- Pressure Testing: Before full operation, pressurize the system gradually and inspect all connections for leaks using soapy water solution.
- Maintenance: Periodically inspect seals and clean the coupling face. Replace if wear or damage is evident.
⚠️ Safety & Compliance
Always depressurize air lines before connecting or disconnecting couplings. Wear appropriate PPE including safety glasses. Ensure all components are rated for your system's maximum operating pressure. This product is designed for compressed air use only—do not use with flammable gases or liquids.
