Frequently asked questions

BOC is introducing new cylinders in response to customer demand. They are a lightweight steel cylinder (compared to other high pressure cylinders) manufactured to international standards, and can be filled to a higher pressure and content than our older cylinders. This means that at a constant flow rate the new high pressure cylinder lasts longer than the older cylinders.

These cylinders have several features that differentiate them from the older, lower pressure cylinders.

Firstly, the newer cylinders can be filled to a much higher pressure. This means there will be more gas in each cylinder. As such, your new cylinder will last longer, meaning reduced downtime for you so you can keep doing what you do for longer.

A large majority of these new cylinders have been fitted with side outlet complex valves. A complex valve features a non-return and minimum pressure retaining device. This device helps stop backflow and corrosion. These features assist BOC to continue to provide you with high quality industrial gases.

These new cylinders form part of BOC’s commitment to continuous improvement and will be introduced into other products in coming years.

BOC is committed to providing a high quality and safe products to our customers. We conduct regular testing on all our products to ensure that they meet or better the specified quality. All BOC’s cylinders are visually checked each time they are filled to ensure that they are safe and in good condition.

For the new cylinders, the price of the gas per m3 will stay the same. As there is more gas in each cylinder, total price for gas in a cylinder will increase (unless there is no change in the cylinder volume, then the total price for gas in a cylinder will remain the same). Other charges including handling, delivery and container service charges will remain the same as the original cylinder. This is despite the significant investment BOC is making in these new cylinders. For example, the container service charge for a new D2 cylinder will remain the same as the schedule price of an old D sized cylinder.

Please note: cylinder charges and gas pricing are subject to review.

No. In order to raise the bar, BOC will be replacing the older cylinders with new cylinders. The older cylinders will be condemned and will not be available in products which have been upgraded.

Regulators manufactured to Australian Standard AS 4267-1995 can be safely used with the new high pressure cylinders. Regulators marked/stamped with AS 4267 comply.

If your valve has been tampered with or modified then BOC cannot tell whether or not a regulator complies with AS 4267-1995, even if it is properly marked. If you suspect that your valve has been tampered with or modified, you should not use it.

BOC recommends that you use one of the following regulators:

Your new cylinder can be identified by the addition of a ‘2’ next to the cylinder size listed on the shoulder label. For example, a G sized cylinder will become a G2 sized cylinder, E will become E2 and so on.

The new cylinders may also have a ‘New Product’ neck tag or shoulder sticker.
