What’s the difference between this tool and the others on the market? Are they all the same?
Junhao Lo –
Thank you for reaching out and asking about the difference between our Problue S-05 Adjusting tool and others on the market. The main difference lies in the materials and design of the adjusting tip. Our tool features a stainless steel flat screwdriver-like tip, which is more common and generally easier to use for calibrating regulation orifices. While other tools may be made from cheaper materials or have different tip designs, our Problue S-05 has been designed with durability and functionality in mind.

I’ve been using the Problue S-05 for a while now and it’s been a reliable tool. However, the screwdriver tip can be a bit stiff at times, which makes it difficult to adjust the regulator’s orifice. But overall, it’s a great tool for the price.
Rachel Teo –
Will this tool fit my regulator’s hose? Is there a compatibility chart available?
Junhao Lo –
Thank you for your question about the Problue S-05 Adjusting tool. We’re happy to help. Our Problue S-05 tool is designed to connect in-line between the 2nd stage case and the hose, and it works with most 2nd stages that have a slotted regulator orifice. If your regulator’s hose has a common slotted regulator orifice, the tool’s stainless steel adjusting tip should fit. However, for exact compatibility with your regulator model, please refer to our product documentation or contact us directly at [email protected] for more information. We’ll be happy to verify compatibility for you.

What are the possible causes of the Problue S-05 Adjusting tool not turning the air inlet orifice? Could it be due to improper use or a faulty part?
Imran Hanafiah –
Dear Ling Lee, thank you for reaching out to us about your concerns with the Problue S-05 Adjusting tool. There could be a few possible causes for the air inlet orifice not turning, including wear and tear on the orifice itself, improper insertion of the tool, or a malfunctioning tool. However, it’s unlikely that the issue is due to a faulty part. We would recommend checking the user manual for guidance on correct usage, and ensuring that the tool is properly aligned with the orifice. If the issue persists, please don’t hesitate to contact our customer support team for further assistance. We appreciate your feedback and would be happy to help you resolve the issue.

Can I use this tool with different types of regulators?
Imran Hanafiah –
Thank you for your question, Nancy. The Problue S-05 Adjusting tool for 2nd stage is designed to be versatile and can be used with different types of regulators. However, it’s essential to note that it’s specifically tailored for regulators with an adjustable air inlet orifice. This means it will work best with regulators that have a slotted orifice. If you have any other questions or need further clarification, please don’t hesitate to ask. Have other customers used this tool with their regulators? Share your experiences in the comments below!
