When installing hanging hardware, which material should be used?

When installing hanging hardware, the material that should be used is Teflon tape. This tape is specifically designed to create a seal on threaded connections, preventing leakage and facilitating a secure attachment. It helps to lubricate the threads, making it easier to tighten connections without risking damage to the threads themselves.

Teflon tape is also resistant to chemicals, temperature fluctuations, and aging, making it suitable for various environments, particularly in vapor recovery systems where exposure to different substances and conditions can occur. In contrast, options such as RTV silicone or pipe thread compound may be used in specific sealing situations, but they are not ideal for use specifically in hanging hardware installations where a reliable, easy-to-apply seal is needed for threaded connections.

Using a PTFE gasket instead might be suitable for some applications, but in the context of hanging hardware where straightforward thread sealing is required, Teflon tape remains the preferred choice for its reliability and ease of use.
