When selecting phthalate-free tubing for your peristaltic pump, be sure to verify its compatibility with your specific application requirements and regulatory standards to ensure compliance and optimal performance.

Fluoropolymer Tubing

Fluoropolymer tubing is an advanced option for peristaltic pumps, offering exceptional chemical resistance and temperature tolerance. Made from materials such as PTFE (polytetrafluoroethylene) or FEP (fluorinated ethylene propylene), fluoropolymer tubing is highly inert and can withstand exposure to aggressive chemicals, high temperatures, and extreme conditions. This makes it an ideal choice for demanding applications such as chemical processing, pharmaceutical manufacturing, and laboratory research, where the pumped fluid may be highly corrosive or reactive.

One of the main advantages of fluoropolymer tubing is its non-stick and low-friction properties, which prevent adhesion and buildup of the pumped fluid on the tube surface. This leads to improved fluid flow, reduced maintenance requirements, and minimal risk of contamination, especially in sensitive applications where cleanliness and purity are essential. Fluoropolymer tubing is also known for its excellent dielectric properties, making it suitable for use in electrical and high-purity fluid handling systems.

While fluoropolymer tubing offers superior performance, it is generally more expensive than other types of tubing and may require specialized installation and handling due to its unique properties. Additionally, care should be taken to ensure compatibility with specific peristaltic pump models, as fluoropolymer tubing may have different elasticity and compression characteristics compared to traditional elastomeric materials. Overall, fluoropolymer tubing is an excellent choice for applications requiring the highest levels of chemical resistance, purity, and durability.

Nitrile Tubing

Nitrile tubing, also known as Buna-N or NBR (nitrile butadiene rubber) tubing, is a versatile and cost-effective option for peristaltic pumps. Nitrile rubber is known for its excellent resistance to oils, fuels, and hydrocarbons, making it a popular choice for applications such as fuel transfer, oil pumping, and industrial fluid handling. Nitrile tubing is also available in FDA-compliant grades, making it suitable for use in food processing, beverage dispensing, and other sanitary applications where regulatory compliance is essential.
