No matter how you spell it out and rearrange the numbers, the manufacturer has made this bypass cap for refrigerator filters in their Kitchenaid, Whirlpool and Maytag refrigerators no longer available. We suppose it makes more sense for them to sell water filters every 6 months than a one shot bypass plug only once. However we have found some. Original and available - while supplies last. I am not on e-bay, or amazon, although there are quite a few names out there that resemble mine. Pricing and shipping rate will be supplied once you call in or reach out by chat or email.
This bypass plug will replace and bypass systems that use filters, EDR4RXD1B, 4396395, W10735404, 67003591, UKF8001
