Teflon® is commonly used to manufacture which of the following?

Teflon® is widely utilized in plumbing applications primarily due to its exceptional chemical resistance and low friction properties. In the context of plumbing components, it is particularly effective for use in compression washers. Compression washers, often found in faucets and fixtures, require materials that can provide a watertight seal without degrading quickly over time. Teflon®'s ability to withstand different chemicals and environmental conditions makes it an ideal material for manufacturing these washers, allowing them to maintain their integrity and functionality.

While packing nuts, gate valves, and ball valves have their specific materials and standards, they do not typically utilize Teflon® to the same degree as compression washers do in plumbing. Each of these parts may incorporate other materials for their construction, such as metals or rubber, which are more suitable for their particular functions and pressure requirements. Thus, the selection of Teflon® for compression washers highlights its unique advantages in ensuring reliable seals within plumbing systems.
