Tefen barb connectors are designed to operate with all PE tubes class 2.5-4 PN, at the range. They can work with other flexible plastic and rubber pipes. The fitting and sealing mechanism is based on a barb that holds the tube from the inside diameter. This is a push fit solution and hose clamps are not required. Fittings size indicate the nominal outside diameter of the Tube. For example 5/8" barb fitting, fits a 5/8" irrigation tube class 2.5, with inner diameter of 1/2". Tefen barb connectors are essential components in fluid transfer systems, widely used in various industries including medical, agricultural, and industrial applications. These connectors are designed to securely join flexible tubing to rigid pipes or other fittings, ensuring a leak-free connection that can withstand pressure and temperature variations. Made from high-quality materials such as polypropylene and polyethylene, Tefen barb connectors offer excellent chemical resistance and durability. Their unique barb design provides a strong grip on the tubing, preventing disconnection during operation. Available in multiple sizes and configurations, Tefen barb connectors cater to diverse needs, making them an ideal choice for professionals seeking reliable fluid handling solutions.
