Product Overview
The PVC twin clear hose features a parallel dual-channel design, creating two independent flow paths within a single hose. This structure retains the visibility advantages of standard PVC clear hose while enabling simultaneous transfer of different liquids.
Made from food-grade PVC material, the hose has uniform wall thickness with a separation layer between the two channels to prevent liquid mixing. Common specifications include combinations like 6mm/8mm or 8mm/10mm inner diameters, with the overall outer diameter slightly larger than single hoses while maintaining good flexibility.
Compared to single hoses, the twin design reduces tangling issues and is particularly suitable for applications requiring concurrent transfer of two media. The transparent material allows visual monitoring of liquid flow in both channels.

Usage Precautions
Installation Notes
Verify channel correspondence before connection to avoid reversal
Minimum bending radius should exceed 5x hose diameter to prevent deformation
Operating Guidelines
Flush both channels with clean water before first use
Maintain temperature differences below 30°C when transferring liquids
Maintenance
Regularly inspect separation layer for leaks
Store flat or in large coils to avoid crushing
Cleaning and Care
Routine Cleaning
Flush both channels after each use, using soft brushes if necessary. For food/medical applications, monthly disinfection with 75% alcohol solution is recommended.
Long-Term Storage
Drain all liquid and store dry away from direct sunlight. Quarterly air pressure testing is advised to check separation integrity.
