Frequently Asked Questions

Will this plug work with my RV's water system?
Yes. This 0.5" MPT plug is the standard size for Dometic fresh water, gray water, and black water system connections. It's compatible with most RV plumbing configurations.

Do I need to use thread seal tape or plumber's putty?
We recommend using PTFE (Teflon) thread seal tape on the male threads for a watertight seal, especially if the plug will be under pressure or exposed to vibration during travel.

Can I reuse this plug if I remove it later?
Yes. PVC plugs can be removed and reinstalled multiple times. Simply clean the threads and reapply thread seal tape before reinstalling.
