BraidFlex™ 70N Braided PVC Tubing is engineered for demanding fluid transfer applications that require enhanced pressure resistance and durability. Designed with an embedded polyester braid, this tubing offers superior strength while maintaining flexibility, clarity, and compliance with industry safety standards. Whether used in laboratory settings, pneumatic systems, or high-pressure food and beverage applications, BraidFlex™ 70N Braided PVC Tubing delivers exceptional reliability and performance.
Regulatory Compliance & Safety
BraidFlex™ 70N Braided PVC Tubing meets NSF-51 and NSF-61-G certifications, 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. It meets USP Class VI’s strict biological safety requirements, ISO 10993, and 3A dairy 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
BraidFlex™ 70N Braided PVC Tubing is reinforced with a polyester braid, providing superior pressure resistance while maintaining flexibility. Unlike traditional non-reinforced tubing, 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%, BraidFlex™ 70N Braided PVC Tubing ensures longevity in demanding environments.
Key Features
