I’m a bit disappointed that the tank doesn’t come with an O-ring seal. It’s a minor inconvenience, but it would be nice to have it included.
Gabriell Sando –
Is the Problue AC-48-3 Aluminium Tank with Key Ring suitable for use in areas with extreme temperatures? What type of O-rings are needed for this tank?
Imran Hanafiah –
Thank you for reaching out to us, Gabriell Sando. Our Problue AC-48-3 Aluminium Tank with Key Ring is designed to be durable and resistant to corrosion, making it suitable for use in areas with moderate temperatures. However, we do not recommend using it in extreme temperatures (below -20°C or above 50°C), as it may affect the tank’s performance. For areas with extreme temperatures, we suggest exploring our more heavy-duty options, which are designed specifically for such conditions. As for the O-rings, we provide pick-o-ring materials with every purchase. To ensure optimal performance, please choose the O-rings that match your local climate and the intended use. For more information, please don’t hesitate to contact us. We appreciate your feedback!

I purchased this Problue AC-48-3 Aluminium Tank with Key Ring to carry my camping gear. But how can I install O-rings on this tank? Is it suitable for outdoor trips?
Junhao Lo –
Hello Timothye, thank you for your purchase of our Problue AC-48-3 Aluminium Tank with Key Ring. The O-rings on the product are pre-installed by the manufacturer and should not require any additional installation steps from the buyer. They are designed to provide a tight seal between the pieces of the tank when not in use. The tank itself is perfect for outdoor trips as it is durable and made of high-quality materials. However, we recommend cleaning the tank before use to ensure optimal performance. Please feel free to contact us if you have any further questions. We’re here to help.

This product has exceeded my expectations, the aluminium tank is well-built and the key ring makes it so easy to carry around. But can I ask, are there different sizes available?
Junhao Lo –
Thank you for your review, Ronalan Babilon! We’re glad to hear that you’re enjoying your Problue AC-48-3 Aluminium Tank with Key Ring. Unfortunately, this specific product is a fixed size, but we do have other options in our range.

Sharmini Uma Sinnathamby –
Will this product work with my pressurized gas cylinder setup?
Junhao Lo –
Thank you for sharing your interest in the Problue AC-48-3 Aluminium Tank with Key Ring, Sharmini. I understand your concern about using this product with your pressurized gas cylinder setup. The product description doesn’t provide detailed information about compatibility with specific gas cylinder settings. However, based on customer reviews and general Aluminum Tank usage, it’s likely that this product will work with standard pressurized gas cylinder setups. If you could provide more details about your specific setup, I’d be happy to help you determine compatibility. You may also contact our customer service team for further assistance.

Unfortunately, I had some trouble with this product as the lid doesn’t fit perfectly sometimes but the quality of the aluminium material still makes it worth the price.
Maylan Wong –
I’ve been using this tank for a month now, and I’m completely satisfied. It’s so easy to carry around with the key ring attached! What do you mean by Pick O-rings on the description though?
Imran Hanafiah –
Thank you for sharing your positive experience with the Problue AC-48-3 Aluminium Tank. We’re glad you find it convenient to carry around with the key ring attached. Regarding the ‘Pick O-rings’ description, we’re assuming it’s a mistake and have already informed our team to correct it. An O-ring is a rubber sealing ring, but in this case, it’s not related to our product. We appreciate your feedback and will make sure to provide more accurate information in the future. Thank you for choosing our product!
