Achieve Leak Free And Safe Connections With Tubing Sleeves

Connecting capillary tubing to coned receiving ports can be challenging—ports are rarely designed for direct tubing use, and fixed-length ferrules often create leaks or unwanted dead volume. IDEX Health & Science offers tubing sleeves as a flexible, cost-effective solution to these challenges, ensuring reliable, low–dead-volume connections across life science and medical device applications.

Unlike ferrules, tubing sleeves are not permanently attached, allowing them to accommodate varying port depths. Extruded polymer construction ensures consistent concentricity and alignment for secure, leak-free connections. MicroTight® Tubing Sleeves, made from PEEK polymer, are pressure rated up to 4,000 psi (276 bar), operate up to 125 °C, and feature color-coded inner diameters for quick identification. NanoTight™ Tubing Sleeves, manufactured from FEP fluoropolymer, also handle pressures up to 4,000 psi and are optimized for 1/16” OD tubing, with a recommended operating temperature of 50 °C.

For higher pressures or stainless-steel fittings, 1/16” and 1/32” OD PEEK Tubing Sleeves provide ratings up to 6,000 psi (414 bar) and temperatures up to 125 °C. These sleeves work with wrench-tightened fittings such as SealTight™, or standard nuts and ferrules (U-400, U-401), providing versatility across multiple instruments.

By using tubing sleeves, researchers achieve safer, cleaner, and more reliable connections while maintaining system flexibility. With a broad range of sleeve materials, sizes, and compatibility options, IDEX Health & Science tubing sleeves streamline assembly, protect sensitive flow paths, and support demanding laboratory and medical applications.
