Welcome to Bottle Swap

OnGas is a nationwide supplier of 9kg exchangeable cylinders which we call Bottle Swap.

Our Bottle Swap service is available at various retailers throughout New Zealand including service stations, hardware stores and convenience stores. We offer consumers a safe and convenient alternative to traditional methods of refilling gas cylinders.

Exchanging cylinders is easy!

OnGas removes all the complexities when it comes to your 9kg gas bottles. Simply take your empty cylinder to any bottle swap outlet and swap it for a full one that's good as new.  No more waiting, no more time wasting!

All our bottles are fully refurbished, safety checked and leak tested, so we can ensure that you'll get a safe bottle every time! It’s the safest and most convenient way to receive a full 9kg gas bottle!

If you don’t own a gas cylinder, don’t worry you can buy one at any bottle swap outlet.

Whether it’s for the bach, the bbq or the outdoor heater, bottle swap is quick, safe and convenient!
