Yee Chen –
What kind of rubber does it use and where can I get this kind of rubber?
Junhao Lo –
Thank you for your review of the Problue AC-96-4 Tank Valve Knob! We appreciate your interest in the materials used in our products. The rubber material used in our AC-96-4 Tank Valve Knob is a synthetic rubber, specifically EPDM rubber, which is known for its durability and resistance to chemicals. However, we don’t provide the exact same rubber for purchase as it’s a custom-made component for our valves. If you’re looking for a similar rubber material, you may want to consider contacting a local plastics or rubber supplier in your area or searching online for EPDM rubber products. Please let us know if there’s anything else we can help with!

Will you be introducing a silver-colored model in the future? A minor negative is that it takes a bit of force to turn the valve knob.

The Problue AC-96-4 Tank Valve Knob is an excellent product. It’s incredibly well-made and has already lived up to its claims. What’s more impressive is the customer service – very responsive and helpful.
Syed Naqi –
Will this valve knob work on both gas and water lines? If not, what else do I need?
Imran Hanafiah –
Thank you for reaching out to us, Syed. The Problue AC-96-4 Tank Valve Knob is designed to work with both water lines, but we do not recommend using it with gas lines due to potential safety risks. If you need a valve knob for a gas line, you may require a special valve designed specifically for gas, which would have additional safety features such as a shut-off valve and may require specific materials. We encourage you to specify the type of line when purchasing so we can recommend the correct product for you.

I’m extremely satisfied with the performance and durability of the Problue AC-96-4 Tank Valve Knob. In fact, it’s the perfect solution for my specific needs. One question though: how does it handle water pressure?
Junhao Lo –
Thank you so much for taking the time to share your experience with us, Lina! We’re thrilled to hear that the Problue AC-96-4 Tank Valve Knob has exceeded your expectations in terms of performance and durability. Regarding your question about handling water pressure, our Tank Valve Knob is designed to withstand a maximum of 3 bar pressure, making it suitable for most residential and commercial applications. However, if you’re dealing with extremely high-pressure situations, we recommend consulting with a professional to determine the best solution for your specific needs. Please note that the pressure rating is detailed on the product listing, and we’d be happy to provide more information if needed. What do you think about our products in general?
