Colder Products Company - Options to Luer Fittings

Options to Luer Fittings

In September 2007, Medical Design Technology published an article “Connection Selection: Identifying Fluid Connector Options.” This article addressed the variety of choices between fittings, luers, and couplings and suggests which connection type is best for specific uses.

To help prevent serious medical misconnections and give design engineers connector options, Colder offers a wide variety of small bore connectors. These connectors are designed for use with 1/16″to 3/16″ inside diameter (ID) tubing.

The SRC is a safer small bore connector for medical tubing applications. Not only does it eliminate the potential for dangerous tubing misconnections with luer fittings, it has a more secure latch design and allows tubing rotation to prevent accidental disconnections or kinked tubing. Available in medical-grade polypropylene with a TPE overmold, the SRC offers a smooth, gap free flow path for less turbulence or unswept volume.

The SMC twist-to-connect couplings provide a reliable and more secure alternative to luer-type connections. Colder’s SMC also allows for the tubing to rotate freely when connected. This important feature prevents both kinked tubing and accidental disconnection during use. Available in acetal, polypropylene and polycarbonate, the SMC product line provides a variety of different configurations and cannot be misconnected to luer fittings.


	For some applications, luers fittings are still a small bore connector option. Colder’s luer fittings are suitable for small flow applications, typically less than 1/4", and feature parting line-free hose barbs. They mate with luers manufactured to ISO Standards 594-1 and 594-2.


Colder offers the largest selection of quick disconnect couplings and fittings for medical applications - both standard and custom products. The MPC, PMC, and PLC product lines offer larger flow sizes and other materials and are just a few of the many different proven fluid connector solutions Colder offers.
