New 300 cu ft Steel Oxygen Billet Pierced Cylinder with CGA540 valve

This 300 cu ft steel oxygen Billet Pierced cylinder is formed by forging heated billets, resulting in superior mechanical properties, including high strength and toughness, making them suitable for demanding applications. Billet Pierced cylinders are also less prone to fatigue failure due to their improved metallurgical structure.

Topped off with a CGA540 valve, sage green rust resistant paint and fresh certification within 12 months of shipment, this huge cylinder will be working hard while saving you time and money.

So many applications; oxygen filling systems, therapeutic purposes, metals industry, and welding industry.

Oxygen is used in small amounts as an addition to other gases in welding applications; typically, as 2-5% addition to argon. It enhances arc stability and reduces the surface tension of the molten metal, increasing wetting of the solid metal.

We also recognize shipping charges can play a significant role in a purchase, and that is why we do everything we can to keep shipping rates as low as possible. We do not inflate the price of our products as a mask for free shipping offers. Our product prices are set at the best pricing we can offer, and the amount charged for shipping covers the shipping and delivery of your order. We believe this transparency in costs is the best way to keep you well-informed while receiving the best price available.

  • Navigate to the Shopping Cart page.
  • Click the "Calculate Shipping" link in the cart totals section and enter your Country, State, City, & Zip Code, then select the 'Update' button.

Residential vs Commercial Address
Initial shipping charges calculated in the Shopping Cart are figured using a residential shipping rate unless you have previously entered a commercial address in the ship-to field during a previous checkout session. Deliveries to a commercial address are typically cheaper than deliveries to a residential address and will be reflected on the checkout page once the full address has been entered and the system confirms it is a commercial address.

LTL Freight Shipments
For larger freight or custom orders, we ask you to allow for a 7-10 business day lead time for product preparation and shipping set up. A customer service representative may reach out to you requesting additional information such as liftgate needs, receiving hours, or other order details. Once your order has shipped, you will receive tracking information. LTL Freight Costs will be calculated on the day of shipment and may vary from your initial estimate, resulting in additional charges.

Time to Ship
Product is shipped from Minnesota. Transport time is usually between 1 and 5 days. Orders typically ship out the following business day after the order has been placed. Larger orders, and especially those going via a contracted freight service, may take additional time.
