If the inlet and outlet are at the bottom of the unit and more than 18" away from the flue, you would not need this adapter unless it's a local code requirement.
You would only need to use this adapter with a gas or oil-fired water heater. PEX should be kept at least 18" away from the flue of these units to protect the tubing from the intense heat present there. No adapter is required with electric water heaters. Always check with local plumbing codes, which may have unique requirements.
You can do this if you replace the included fitting with part LF4521075.
This SKU is only one piece; if you require two for your specific application, you will need to purchase the second one.
