A verification collar is a compliance consumable seated between a valve and a cylinder neck that records internal maintenance and cannot be removed without discharging the unit.
1 products · substrates: card stock, synthetic
A ring that seats between a valve and a cylinder neck, captive by geometry rather than by adhesive or wire. It cannot be removed without pulling the valve, which is precisely the point: the record and the maintenance event are physically the same act.
Choose a collar for the long-cycle internal work - the six and twelve year events - and a tag for the annual and monthly checks on the same cylinder. They are not alternatives and a cylinder in service usually carries both.
The neck diameter decides everything, and it is not standard across manufacturers. A collar that does not seat is not a cosmetic problem: it rides up under the valve and reads as a completed service that never happened.

A collar is for the milestone that outlives the tag. It sits around the neck of a cylinder or the body of a component and stays there for years, which is why it is moulded rather than printed on card and why it is sized to the equipment rather than punched for a hook. Choose a collar when the interval you are evidencing is measured in years rather than months, most commonly an internal examination or a rebuild. The mistake to avoid is ordering collars at tag quantities: only a fraction of a fleet reaches a multi-year milestone in any given year, so collars bought at tag volumes sit in a drawer while the tags run out.
The collar exists precisely because a tag cannot be trusted to carry a long interval, and serialisation is what finally makes that reliable. Even a collar can be cut off during a rebuild or replaced by a technician who did not have the right colour to hand, and once it is gone the multi-year date is reconstructed from whatever evidence survived. A record bound to the cylinder keeps the date that was actually recorded. The collar remains the fast visual signal on the equipment, and the record is what settles the question when the collar and somebody's memory disagree.
The record mechanics are the same for every artifact and are set out on how inspection records work.
Collars are proofed the same way as tags, with the year and your imprint rendered at actual size before anything is charged. Collars are moulded rather than printed, so they take longer in production than card tags do. They arrive serialised, so a collar fitted at an internal examination binds to that cylinder on its first scan and the multi-year clock is recorded rather than inferred. Because the quantities are small and the intervals long, most customers order collars once a year alongside a much larger tag order rather than on their own.
The full sequence, including what the proof shows and how approval works, is on how ordering works.
Count the units actually reaching their multi-year milestone in the coming year, not the whole fleet. For most operations that is a small fraction of the extinguisher count. Ordering collars in the same quantity as tags is the most common first-order mistake and leaves you holding stock for years.
Yes, the colour convention is what makes the year readable across a room without touching the equipment. Specify the year you are evidencing when ordering. Because collars are cheap and long-lived, ordering the next year at the same time is usually sensible.
The record survives it. That is the specific reason serialisation matters more on a multi-year artifact than on an annual one: the physical evidence has to survive years of handling, and when it does not, the date would otherwise be reconstructed from whatever collar happened to still be attached.
