Recertified 40 cu ft. Steel Nitrogen Cylinder

Recertified 40 cu ft. steel nitrogen cylinder with installed CGA580 valve. A bigger but still affordable alternative to our 20 cu ft steel nitrogen tank.

This cylinder sports thick-walled construction and a tough rust-stop painted exterior. And holds pressure longer than its aluminum counterpart.

Nitrogen can be used in HVAC applications for purging refrigerant lines and completing scale-free brazing jobs. Inert gases can be used for purging refrigerant from tubing, flowing and preventing oxidation while brazing, and pressurizing a system for leak detection or a coolant / cooling system pressure test. You’ll also find nitrogen useful for getting oil out of the way before pulling a vacuum.

You can also use nitrogen to help clean out a drain line. However, you’ll want to be careful; if the PVC pipe isn’t secure, you could create leaks and/or severe structural damage if you flow a compressed gas under too much pressure.

Overall, you can use nitrogen for applications where you’d usually use compressed air. Anytime you work with any kind of inert gas, you need a flow meter and regulator; as opposed to a standard gauge manifold.

Gas blends containing nitrogen can increase the mechanical properties of alloys containing nitrogen and prevent pitting corrosion in welding applications.

Fast Shipping

Gas Cylinder Source knows you need your product now, which is why we offer super-fast shipping and even have an express option. 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.

Calculate Your Shipping
You can calculate your shipping charge in just a few quick steps:

  • Add your desired product(s) to the shopping cart.
  • 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.

Order Tracking
Once your order has been shipped, an email will be sent to you with tracking details as well as a link you can use to track your shipment and find estimated delivery information.
