The carbon fiber shell paired with a 6061 aluminum alloy lining provides a robust internal surface and a resilient exterior you can trust in demanding conditions. With a working pressure of 300 bar, it maximizes air supply per fill while keeping overall weight manageable for extended dives or frequent travel.\u003c\/p\u003e \u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eVolume: 3L\u003c\/li\u003e \u003cli\u003eMaterial: Carbon fiber shell; lining: 6061 aluminum alloy\u003c\/li\u003e \u003cli\u003eWorking pressure: 300 bar\u003c\/li\u003e \u003cli\u003eWeight: 2.3 kg\u003c\/li\u003e \u003cli\u003eMouth thread: M18x1.5\u003c\/li\u003e \u003cli\u003eModel: 3L\u003c\/li\u003e \u003cli\u003eOrigin: Mainland China\u003c\/li\u003e \u003cli\u003eCertification: CEF\u003c\/li\u003e \u003cli\u003eRe-test interval: 3 years\u003c\/li\u003e \u003cli\u003eDesign life: 15 years\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWhy this cylinder stands out\u003c\/h3\u003e\n\u003cp\u003eThe combination of carbon fiber construction with a durable aluminum lining strikes a balance between strength and weight that traditional steel cylinders can’t match. At approximately 2.3 kg, this cylinder minimizes fatigue on long ascents and reduces the effort required to manage your gear between dives. The high-strength carbon fiber outer shell is engineered to withstand the rigors of deep-sea environments, while the 6061 aluminum lining protects the interior from corrosion and wear, helping maintain consistent performance over the cylinder’s long service life.\u003c\/p\u003e \u003cp\u003eWith a 15-year design life and a 3-year re-testing interval, this cylinder is built for divers who plan multiple trips per year and want equipment that won’t require frequent replacement. The 300 bar rating means more air per fill compared to lower-pressure options, enabling longer bottom times or the ability to support larger air volumes on extended dives.\u003c\/p\u003e \u003ch3\u003eIdeal use scenarios\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eRecreational divers seeking lighter gear without sacrificing air capacity\u003c\/li\u003e \u003cli\u003eTech and deep-water divers who require reliable high-pressure performance\u003c\/li\u003e \u003cli\u003eTraveling divers who want a more compact, easier-to-pack cylinder for airline travel\u003c\/li\u003e \u003cli\u003eCold-water or challenging environments where a robust aluminum lining helps resist corrosion\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eCare, safety, and maintenance\u003c\/h3\u003e\n\u003cp\u003eTo ensure optimal safety and longevity, adhere to the following practices:\u003c\/p\u003e\n\u003cul\u003e \u003cli\u003eHave a certified facility conduct hydrostatic re-tests every 3 years as required.\u003c\/li\u003e \u003cli\u003eInspect the cylinder for signs of cracking, delamination, or impact damage before every dive.

Before pairing with gear, verify that your regulator system is rated for 300 bar to ensure safe and efficient delivery of air during dives. Consider pairing with a lightweight regulator system and a reliable neck or back-mount setup to maximize balance and trim, particularly on longer or deeper dives. Regularly check valve protection and mount hardware to prevent accidental depressurization or leaks during transport and rigging.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BullseyeSportingGoods","offers":[{"title":"Carbon Fiber \/ United States","offer_id":43145424044121,"sku":"14:201441572#Carbon Fiber;200007763:201336106","price":220.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/1700\/3097\/files\/S2eaef9426e3541b1b88c847badfa2049e.webp?v=1773261835","url":"https:\/\/bullseyesportinggoods.com\/products\/tuxing-300bar-4500psi-3l-carbon-fiber-cylinder-hpa-bottle-high-pressure-scuba-diving-tank-for-firefighting-diving-m18-1-5","provider":"BullseyeSportingGoods","version":"1.0","type":"link"}
