Good day! No, it's not. This JCM 131-0400-12 repair clamp will only work for pipes with outside diameters that range from 3.73" to 4.13". Please check the table on page 2 of this Manual for reference. If you need a clamp for a 4.30" (OD) pipe, the Cascade CRI-0440 is probably the one that you need. According to the table on page 10 of their catalog, it works for pipes with outside diameters that range from 104 mm to 113 mm or, if converted to inches, 4.09" to 4.4". We are on the process of putting its information on our website but you can already place the order. Just have the product number ready and call our Customer Service Department at 435-868-4020 or simply send a message using the Contact Us tab found on the bottom right part of your screen. Also, please indicate the size that you need. Thank you for shopping at PlumbersStock.com!
