As of 2015, replacement washing machine seals can be found at a number of online retailers, including Sears Parts Direct, Appliance Zone and Appliance Parts Pro. The online retailers offer a variety of shipping options that can result in delivery of parts as quickly as 2 business days.
Sears Parts Direct has a wide selection of replacement washing machine seals available. To find a particular seal, Sears offers searching by both model number and product number. Once the part is found, it also lists other models of washers that the seal is compatible with as well. Manuals for the parts can also be downloaded from the site to aid in the installation of the replacement seals.
Appliance Zone allows for product searching to find specific seals for washers. The information on the seals isn't as detailed as that provided by the Sears site, so ordering from Appliance Zone is likely best when the machine owner has some experience with minor appliance repair or has instructions for seal installation from another source.
Appliance Parts Pro also has a wide range of seals available, but makes finding specific ones easier by allowing searches not only by model and parts number, but also by general description. Once the part is found, the site offers a parts diagram as well as an instructional video covering installation.
