Before You Order. Match the pipe OD and the gasket section to the coupling or fitting; the part number is on the old gasket and in the coupling submittal. Non-stock Dresser parts are not returnable without Dresser’s authorization, and ship time is confirmed when you order. Custom builds (other sizes, widths, gaskets or materials) are available: email
sales@watermainsupply.com with the pipe OD, material and line content.
