I'm interested in your electrofusion fittings and would like to know if they hold any certifications from WRAS or Kiwa. As you know, these certifications are crucial for ensuring product quality and compliance with industry standards in various applications. It's essential for us to partner with suppliers whose products meet these rigorous certifications. Could you provide some details about the certification status of your electrofusion fittings? Additionally, if there are specific models that come with these certifications, I'd be keen to learn more about those too. This information will greatly assist in our evaluation and decision-making process. Looking forward to your prompt response!
