Recertified 60 cuft Steel Nitrogen Cylinder

A recertified cylinder is a used cylinder that has been inspected and hydrostatically retested by a DOT-authorized facility and passed, then returned to service with a fresh test date stamped on the collar. It is not a repaired or second-quality cylinder; it either passes the test or it is scrapped. The practical difference from new is cost and cosmetic finish, not safety.

Yes, when it carries a current requalification stamp. That stamp is the same standard a new cylinder must meet, and gas suppliers apply the same check to both before filling. The test date on the collar is what matters, not the age of the cylinder.

Height, diameter and empty weight for this cylinder are listed in the specifications on this page. As a class, 60 cubic feet is a mid-size bottle: taller than a 20 cu ft, and still movable by one person. Check the listed height if it needs to fit a cabinet, a cart or a service vehicle.

Common uses are HVAC pressure testing and line purging, brazing purge, laboratory and industrial nitrogen supply, and beverage applications such as nitro coffee where a mid-size bottle suits the draw rate. Dry nitrogen is chosen because it displaces oxygen and moisture without introducing either. The right size depends on how continuous the draw is.

It comes with a CGA580 valve, the standard inert-gas connection shared with argon and helium. A CGA580 nitrogen regulator threads on directly. For HVAC pressure testing choose a high-pressure nitrogen regulator that reaches your required test pressure, rather than a low-pressure flowmeter.

The CGA580 connection is shared across inert gases, and suppliers do fill inert-service cylinders with argon, nitrogen or helium. Confirm with your filler before switching a cylinder’s gas service, since some suppliers keep cylinders dedicated to one gas and purity requirements differ by application.

It depends entirely on the task. A series of HVAC pressure tests uses very little gas per test, so a 60 cu ft bottle can cover many jobs, while continuous purging or a beverage application with steady draw depletes it far faster. Watch the regulator gauge and refill before it approaches empty.

No. All cylinders ship empty for transport safety and must be filled before use. Any welding or industrial gas supplier can fill it with nitrogen to the marked service pressure. Specify the purity grade if your application requires one.

You own it outright, with no rental contract and no recurring fees. Ownership is the main reason to buy a recertified cylinder: it removes ongoing rental charges at a lower entry cost than a new bottle. Keep the purchase record and the test date to prove ownership at exchange.

Yes. Suppliers fill on the strength of the current requalification stamp, not on whether the cylinder is new. They will read the collar date and refuse any cylinder, new or recertified, that is out of date.

High-pressure steel cylinders are requalified on a set DOT interval from the last test date stamped on the collar. Because this cylinder has just been recertified, it enters service with a current date and a full interval ahead of it. Check the stamp when it arrives so you know the date.

The 20 cu ft is the portable service-call size, the 125 cu ft is a shop bottle that cuts refill frequency, and the 60 cu ft sits between them. All three share the CGA580 connection, so a single regulator serves any of them. Pick on how far the bottle must travel against how often you want to refill it.
