140237163021 Genuine O-Ring Seal INSOR 119C02 for Electrolux Group Appliances, Factory Replacement Sealing Ring

Part 140237163021 is a genuine Electrolux group O-ring seal, catalogued with the reference INSOR 119C02. O-rings form a watertight or airtight seal between two fitted parts, such as a pump, heater, hose fitting or housing. The size isn't on file, and a similar seal with the reference INSOR 109C02 is stocked as 140237163013, so it's important to match the number and reference rather than guess by eye.

Leaks from a worn O-ring

An O-ring works by being squeezed slightly between two surfaces, filling the gap so water, air or gas can't pass. Over time, heat, detergent and age harden the material, and it flattens into the shape of its groove instead of springing back. Small drips, weeping around a fitting, white scale trails or damp patches under the appliance are the usual signs. Seals can also be nicked when parts are taken apart. Whenever a joint is opened for repair, fitting a fresh O-ring is a sensible habit that heads off a return leak.

Fitting a new O-ring

Isolate power and water before opening any joint, and have a towel ready for trapped water. Remove the old ring with a plastic pick so the groove isn't scratched, then clean the groove thoroughly. Lightly wet the new O-ring with water, or use a silicone grease if the appliance maker allows it, and seat it evenly without twisting. Reassemble and check for leaks under normal running.

Questions about this part

Can I use a hardware store O-ring?

Only if the size and material match exactly, which is hard to confirm by eye. Appliance seals are chosen to cope with heat and detergent. Using the genuine 140237163021 avoids guesswork when your old ring matches the INSOR 119C02 reference.
