For logistics reasons, our Customer Care team is unable to answer questions regarding specific dates of manufacture or expiration on products with limited shelf life such as: rebreather oxygen sensors with 6 month shelf life, CO₂ absorbents with 60 month (five year) expiration dates, and cylinders with 60 month (five year) hydro re-test dates. We guarantee you will receive products dated well within current supply-chain norms: rebreather absorbent and cylinders will be less than two years from date of manufacture, oxygen sensors will be less than six months from date of manufacture.

We turn over our inventory frequently and can assure you that the products we ship are fresh.
