NEST Reducer Tube Connectors provide a flexible solution for transitioning between different tubing diameters within a closed fluid path. Their secure barbed design, smooth internal surface, and wide selection of sizes support efficient system configuration in biopharmaceutical and single-use fluid-transfer applications.
It connects two pieces of compatible flexible tubing with different inner diameters, allowing the fluid path to transition from one tubing size to another.
Each barbed end is inserted into appropriately sized tubing. The dual-size barbed design helps retain both tubes and maintain a secure, sealed fluid path.
NEST Reducer Tube Connectors are manufactured from polypropylene that meets USP Class VI requirements.

Select a configuration that matches the inner diameter of each tube. Tubing material, wall thickness, flexibility, operating conditions, and assembly method should also be evaluated.
The connector provides a transition between two tubing sizes and may be incorporated according to the required flow direction. Users should evaluate the complete assembly for its intended flow rate, pressure, and process conditions.
Yes. Its smooth internal surface is designed to reduce flow restriction, residual liquid, and product hold-up during transfer.
No. NEST Reducer Tube Connectors are supplied non-sterile.
Yes. It supports either irradiation at 50–55 kGy or steam sterilization at 121°C for 30 minutes. Users should validate the selected process for the completed assembly.
No. The two sterilization methods are mutually exclusive and must not both be applied to the same connector.
Yes. The product documentation states that it complies with USP <87>, USP <88>, and ISO 10993 requirements.
They are suitable for tubing-size transitions in media and buffer transfer lines, sampling systems, filtration assemblies, manifolds, bioreactors, storage systems, and other single-use fluid paths.
Yes. The Tube Connector Collection is identified as animal-origin-free with respect to BSE/TSE.
Each manufacturing lot is sampled and tested for appearance and dimensions, sealing performance, temperature tolerance, and insoluble particulates.
The connectors have a five-year shelf life from the date of manufacture when stored at room temperature with the packaging intact.
NEST Reducer Tube Connectors are double-layer packaged with 100 connectors per bag.
