Caltric Deck Wash Water Port Plate Compatible with John Deere Z375 Z425 Z435 Z445 Z465 Z515E Z525E

What It Is

This is an aftermarket deck wash water port plate that replaces the factory-installed port on select John Deere Z-Series zero-turn mowers. It lets you attach a garden hose directly to the mower deck for quick cleaning of grass clippings and debris.

Fitment & Compatibility

Before buying, confirm your mower model is listed: John Deere Z375, Z425, Z435, Z445, Z465, Z515E, or Z525E. The port plate is designed to mount on the top of the deck and uses a standard 1/4-inch quick-connect fitting. Check that your deck has a pre-drilled hole (typically 1.5 inches in diameter) and a flat mounting surface. This Caltric part is an aftermarket replacement for OEM part number M160822. If your deck has a different port design or no port at all, you may need a different kit or additional hardware.

Key Things to Know

• Quality: Caltric is a budget aftermarket brand. The plate is made of plastic, not metal—less durable than OEM but functional for occasional use.
• Installation: Simple—remove the old port (if present), clean the deck surface, and screw in the new plate. No special tools required.
• Common gotcha: The included gasket may not seal perfectly on all decks. Apply a thin bead of silicone sealant around the port hole before installation to prevent leaks.
• Hose connection: The port uses a standard garden hose quick-connect. If your hose has a different fitting, you’ll need an adapter.

Should You Buy It

Buy this if you need a cheap, easy replacement for a worn or missing deck wash port on a compatible John Deere Z-Series mower and don’t mind a plastic part that may need a little sealant to work reliably. Skip it if you want a metal, OEM-grade port or have a different mower model.
