Description
Overview:
The PCL Safeflow Coupling 7.9mm (5/16 inch) I/D Hose Tail - SC21S is a safety quick‐release pneumatic coupling for compressed air lines on construction and garden machinery. Built with a durable metal body and a corrosion‐resistant finish, it is designed for regular use in workshops and on site. The 7.9mm (5/16 inch) internal diameter hose tail fits small‐bore rubber or PVC air hose, providing a reliable connection for air tools and equipment. Safeflow technology helps manage air flow and disconnection safely, supporting efficient operation of tools such as impact wrenches, nailers, blow guns, tyre inflators and general workshop airlines. The coupling connects to matching PCL adaptors of the same series and profile, making it a practical choice for maintenance, repair and installation tasks across a wide range of pneumatic setups.
Key Features:
- 7.9mm (5/16 inch) I/D hose tail for a secure fit on common small‐bore air hose
- Safeflow two‐stage release vents downstream pressure before disconnect to reduce hose whip and noise
- High air throughput to help tools run efficiently
- Robust metal construction with a wear‐resistant, corrosion‐resistant finish
- Positive sleeve action for quick, one‐handed connection and release
- Compatible with PCL adaptors of the same series/profile
- Simple to fit using a suitable hose clip or crimp ferrule
- Suited to workshop, site and mobile service use in demanding conditions
Typical Applications:
Used on compressor airlines for connecting air tools, spray equipment, tyre inflation devices and blow guns. Suits maintenance of construction equipment, garden machinery servicing, and general workshop setups. Ideal for tasks where frequent, safe connect/disconnect is needed while maintaining consistent airflow and minimising hose movement.
