Overview
The Foster SV6706 is a safety vent coupler from the ZSi-Foster SV Series, engineered for maximum safety in pneumatic and hydraulic systems. This 1″ male pipe thread (MPT) connection is a quick-disconnect fitting that allows safe, easy connection and disconnection under zero line pressure. The steel body with silicone-free assembly design prevents accidental disconnect and potential hose whip incidents, making it essential for high-safety applications.
Key Features
- Zero-Pressure Design: Vents downstream pressure during disconnect, eliminating dangerous hose whip and accidental separation.
- Safety-Focused Construction: Minimizes inadvertent disconnection and reduces risk of pressure-related accidents in pneumatic and hydraulic lines.
- Non-Marring Encapsulation: Fully encapsulated design reduces risk of surface nicks and scratches on finished materials.
- Heavy-Duty Steel: Extra thick, heat-treated steel walls extend service life in demanding environments.
- Silicone-Free Assembly: Meets ISO 4414 quick-action coupling standards without silicone contaminants.
- Industrial Interchange Compatible: Designed for industrial standard quick-disconnect applications across multiple systems.
