Does anyone know if the internal probe is adjustable for different types of regulator orifices?
Imran Hanafiah –
Thank you for reaching out, Yeong. The internal probe on the Problue S-05-3 Adjusting tool is designed to be versatile and can accommodate a range of regulator orifices. While it’s primarily made for the more common slotted orifices, its internal design allows for some degree of adjustability. However, for optimal results, it’s recommended to refer to the product’s manual or manufacturer’s guidelines for specific recommendations on usage and compatibility.

I’m not entirely sure how I handled 2nd stage adjustments in the past without this tool. It’s been a game-changer for me. I’ve tweaked my regulator to deliver a spot on 80/20 mix with just a few twists.

Rashid Jumat – First time purchasing this Problue S-05. I’ve used similar tools before, and I’m glad to see how this one fits a variety of 2nd stages. The stainless steel flat screwdriver tip is a great feature, as it fits commonly used slotted regulator orifices.
Tan Kok Siong –
Will this Problue S-05-3 tool work with my regulator 2nd stage with a small hex screw instead of a slotted orifice?
Junhao Lo –
Thank you, Tan Kok Siong, for reaching out to us about your Problue S-05-3 adjusting tool. I’m sorry to hear that your regulator 2nd stage has a small hex screw orifice instead of a slotted one. Our Problue S-05-3 tool is specifically designed with a stainless steel flat screwdriver-like adjusting tip, which is suited for slotted regulator orifices. Unfortunately, this tool might not be compatible with your hex screw orifice type. However, I’d like to suggest contacting our support team or reaching out directly to our manufacturer to explore possible solutions or recommendations for your specific regulator model. We appreciate your business and hope to be of assistance.
Pang Chu Hing –
I have mixed feelings about using this product. I like how easy it is to use, but the tip on the adjusting tool seemed a bit loose. That’s my only complaint.
Leong Jiameng –
Does anyone know if this adjusting tool is compatible with Sea Flo 45 2nd stage?
Imran Hanafiah –
Thank you for your question, Leong Jiameng! After verifying the compatibility of our Problue S-05-3 Adjusting tool, we found that it should work with the SeaFlo 45 2nd stage. The internal probe feature of this tool can fit most slotted regulator orifices, which is common for many regulator 2nd stages. However, we recommend checking the specifications of your SeaFlo 45 2nd stage to ensure its compatibility with our adjusting tool. If you have any further questions or concerns, please don’t hesitate to reach out to us. We’re here to help! You can also refer to our product documentation for more information on compatibility.

This material is ideal for use with regulator 2nd stages, ensuring a precise and long-lasting calibration. I hope this answers your question, Liao Yiming.
