Elkhart Products Corporation Serving the residential, commercial and industrial plumbing markets with American ingenuity. Welcome to our Website! We're glad you stopped by, and we're excited to tell you not only about our copper plumbing fittings, but we also want to share with you what we think is a re-birth of our company. Elkhart Products Corporation has put the industry's old-style, single-line product philosophy on hold and has become an aggressive, fundamentally changed company, top-down, bottom-up and sideways! You'll see it in our new product lines, and you'll feel it as you work with all levels of our professional staff. So browse through our Website, see what copper fitting products we have to offer to our residential, commercial and industrial plumbing customers, then contact us so we can tell you more.
