RV Inline Water Filter Caps – Storage Plug Set

RV Inline Water Filter Storage Caps

These caps are designed to seal both ends of a standard RV inline water filter for storage and transport. After disconnecting a filter, water often remains inside and can drip into storage bins, cabinets, or toolboxes. These caps allow you to quickly close both ends of the filter to keep things clean and dry.

The model includes three parts:

• Male cap – seals the female side of the filter
• Female cap (standard) – simple threaded cap
• Female cap with TPU gasket – allows for a tighter seal when the filter still contains water

The TPU gasket version compresses slightly when tightened, helping prevent slow drips during storage.

These caps are ideal for RV owners who want to keep their gear organized and avoid water leaking after disconnecting their filter at a campsite.
