Many customers use thread sealant tape, sometimes known as Teflon tape, to seal water connections on washers and refrigerators, but this product is not necessary in most applications. Thread sealant tape is used only on certain metal-to-metal fittings. If your application uses a supply line with rubber washers (like a garden hose), compression fittings (made of brass), or push-in fittings (like Shark Bite), sealant tape is not needed.
