Husqvarna Genuine 532415598 & 532416405 Washout Port & Quick Connect Coupling

What It Is

This is a Husqvarna Genuine washout port kit (two part numbers, same function) that lets you connect a garden hose directly to your mower deck for quick under-deck cleaning. Designed for riders and zero-turns with a stamped steel or fabricated deck.

Fitment & Compatibility

• Check your deck: Fits most Husqvarna, Poulan Pro, and Craftsman (with Husqvarna-made decks) models from the mid-2000s onward. Not for walk-behinds or decks with a pre-installed port that uses a different thread size.
• Deck size: Works on 42- to 61-inch decks, but measure the port hole diameter on your deck (typically 1/2" or 5/8") to confirm the rubber grommet fits.
• OEM vs aftermarket: This is a genuine Husqvarna part – aftermarket knockoffs often have a looser grommet seal or a plastic coupling that cracks faster.
• Model lookup: Verify your mower model number (e.g., YTH24V48, MZ61) on Husqvarna’s parts site or call support. If your deck has an existing port, check if it’s a 90-degree or straight fitting – this kit includes both.

Key Things to Know

• Installation is easy – drill a 1/2" hole (if no port exists), insert the rubber grommet, and snap in the port. No special tools needed.
• Sealing matters – the rubber grommet can dry out over time; apply a dab of silicone grease at install to prevent leaks.
• Common gotcha: If your deck already has a port, don’t assume this kit’s threads match. Husqvarna uses two thread sizes (3/8" and 1/2"), so measure before buying.
• Use with care – running the mower with the hose connected can spray water into the engine bay; always disconnect before starting.

Should You Buy It

If you own a Husqvarna or compatible rider/zero-turn and want a convenient, low-cost way to rinse grass clippings off the deck without crawling underneath, this kit is a solid buy. It’s reliable, easy to install, and the genuine part fits better than generics. Skip it if your deck has a different thread pattern or you prefer a pressure washer for deeper cleaning.
