Coaxial Circuits are designed with a durable outer tube that encases a flexible inner tube which carries inhaled gases. The exhaled air in the outer tube helps heat the gases in the inner tube as it travels from the anesthesia machine to the patient.
Note: All circuits featured above come with an integrated CO2 GSL. Some of the circuits and kits may have an initial lead time.

Company Return Policy
Endure Policy on Returns: As a customer you always maintain the right to return a product you no longer wish to use as long as the product is still in good, working condition (i.e. unopened/unused for disposables). For products returned within 90 days of purchase, we will issue a full refund upon receipt of the return. For returns made after 90 days of purchase, an Endure representative will be happy to discuss refund and credit options.
To help facilitate the returns process, your Endure Customer Service Representative will provide you with a prepaid return label free of charge. For single-use devices that have been opened, we usually recommend that you discard the product and request a substitute right away. Our support staff also works with you in each instance to find the product replacement/refund approach that is most cost-effective and helpful for you!
