It’s NOT an expiration date! It’s the BORN date, or date the tank was made. Brand-new tanks are tested and stamped with a “born date” located near the neck of the bottle. Tanks are good for 5 years until re-testing will be required.
5 Year HYDRO CYCLE EXPLAINED.. The term "hydro cycle" refers to the process of hydrostatic testing. Hydrostatic testing is a mandated safety measure to ensure tanks remain structurally sound under pressure, etc.. All paintball tanks undergo an initial hydrostatic test to ensure they meet safety standards. This test determines the tank’s “Born Date” or date of manufacture. From there, all tanks require re-hydrostatic testing every 5 years - Hence, 5 YEAR HYDRO CYCLE.
Expect “Born Dates” within up to 1 year of purchase. All Tanks ship empty. Tanks must be filled prior to use.
Paintball tanks are typically filled at your local paintball field, sporting goods store, welding supply shop, brewery supply, SCUBA shop, etc. Double-check in your local area prior to purchasing to ensure convenient tank fills! Be sure to specify CO2 vs. HPA Compressed Air filling services.
