L-Shaped Connectors, Polypropylene for Laboratory Tubing

Description

The L-Shaped Connectors, Polypropylene, also known as polypropylene elbow connectors, 90-degree tubing connectors or laboratory L-shaped fittings, are designed to connect two sections of compatible laboratory tubing while changing the direction of liquid flow by 90 degrees. Manufactured by PolyLab, these laboratory tubing connectors feature durable polypropylene (PP) construction for routine liquid transfer and circulation applications. Their lightweight, rigid structure provides a practical connection point between flexible tubing sections used in laboratory fluid handling systems.

The 90° L-shaped design allows users to redirect tubing around laboratory equipment, containers and other components without creating a sharp bend in the flexible tube itself. This helps organise tubing arrangements and reduces the likelihood of flow restriction caused by tubing kinks. These polypropylene L connectors are available in 6 mm, 8 mm and 10 mm sizes, allowing users to select a suitable fitting for their laboratory tubing. The manufacturer identifies these sizes for tubing with corresponding nominal internal diameters. Actual fit should be checked against the tubing material, internal diameter and wall flexibility.

Each connector is designed to create a secure, leak-resistant joint between two tubing sections. For proper installation, the tubing should be pushed fully onto both connector ends, with the connection checked for secure engagement before liquid circulation begins. Leak resistance depends on the tubing fit, operating pressure and condition of the assembled system. The connectors are manufactured from polypropylene, a laboratory plastic valued for its chemical resistance and durability. Polypropylene is compatible with many water-based solutions and common laboratory chemicals, although resistance varies with chemical concentration, temperature and exposure conditions. Compatibility should be confirmed before use with particular solvents or aggressive chemicals.

These L-shaped tubing connectors are suitable for laboratory liquid transfer arrangements where the direction of flow needs to change without installing additional tubing bends. They can be incorporated into compatible gravity-fed dispensing systems, water circulation arrangements and low-pressure laboratory fluid transfer assemblies. The availability of three connector sizes and pack quantities of 12, 24 and 36 pieces makes the range suitable for laboratories requiring multiple tubing connections across different experiments or routine testing setups. Users can select the appropriate size and pack quantity based on their tubing requirements.

For installation, cut the flexible tubing ends squarely and push each section firmly onto the corresponding connector end. Check that the tubing remains securely fitted and that no leakage occurs during initial operation. Additional retention methods may be necessary where operating conditions require them. Safety Precautions: Verify the chemical compatibility of the polypropylene connector and tubing before use. Avoid excessive pressure, incompatible solvents and temperatures outside the permitted operating range. Do not assume suitability for high-pressure or high-temperature applications without confirmed manufacturer specifications. The product is supplied as the selected PolyLab Polypropylene L Connectors in 6 mm, 8 mm or 10 mm size, with pack quantities of 12, 24 or 36 pieces as selected. Flexible tubing, pumps, clamps and other laboratory accessories are not included unless specified separately.

LabChoice Australia supplies Polypropylene L Connectors and laboratory tubing accessories for chemistry laboratories, university teaching facilities, research institutions, industrial testing laboratories and quality control environments requiring reliable fluid transfer connections.
