I'm currently in the market for butyl tubes and would appreciate your assistance. Specifically, I'm interested in a few sizes that are commonly used in various vehicles. Could you provide more details about your available options? Additionally, I would be grateful if you could send me your product catalog, including any specifications or options you have for these tubes. This information will be really helpful for my selection process. Thank you!
