Final answer:
Teflon tape is the only approved lubricant for swivels on hoses.
Step-by-step explanation:
The only approved lubricant for swivels on hoses is Teflon tape. Teflon tape is a non-stick material that is commonly used in plumbing applications to create a seal and prevent leaks. It is a thin tape that is wrapped around the threads of the swivel to provide lubrication and reduce friction.
One example of how Teflon tape can be used on a hose swivel is in a garden hose connection. The Teflon tape is wrapped around the threads of the swivel to create a tight seal and make it easier to connect and disconnect the hose.
In addition to Teflon tape, there are other lubricants that may be used on swivels for hoses, such as silicone grease or specialized lubricants designed for specific applications. However, Teflon tape is often the preferred choice due to its effectiveness and affordability.
