WaterFLEX™ 70G/W Braided PVC Tubing is engineered specifically for reliable potable water transfer and deionized water applications. Enhanced with an inner nylon braid, this tubing provides the structural integrity needed to withstand much higher pressures while maintaining the flexibility for easy installation. With a non-marking opaque cover that helps reduce UV degradation, WaterFLEX™ 70G/W Braided PVC Tubing delivers dependable performance in water, laboratory, and food and beverage applications.
Regulatory Compliance & Safety
WaterFLEX™ 70G/W Braided PVC Tubing is NSF-51 and NSF-61-G listed, ensuring suitability for food and potable water applications. Manufactured from FDA-compliant ingredients, it is approved for all food types, including beverages containing up to 50% alcohol, under conditions of use B through H, not to exceed 100°C. It meets USP Class VI’s strict biological safety requirements, ISO 10993, and 3A standards for milk transfer, making it ideal for critical fluid handling applications.
The tubing is RoHS and REACH compliant and free from PFAS, Proposition 65-listed chemicals, and EPA TSCA-listed substances. Additionally, it meets UL94 HB/V-1 flame resistance standards and offers self-extinguishing properties that enhance safety in industrial environments.
Material Performance & Durability
WaterFLEX™ 70G/W Braided PVC Tubing is reinforced with an inner nylon braid, providing superior pressure resistance while maintaining flexibility. Its embedded braid design prevents material entrapment and allows easy cleaning.
The tubing operates within a temperature range of -5°F to 175°F (-21°C to 80°C) and supports high-pressure applications with a maximum working pressure of 276 PSI at 73°F and 138 PSI at 125°F. With a tensile strength of 2,425 PSI and an ultimate elongation of 400%, WaterFLEX™ 70G/W Braided PVC Tubing ensures longevity in demanding environments.
