Husqvarna 2 Pack Genuine 532416405 Washout Port Quick Connect Coupling OEM

What It Is

This is a genuine OEM Husqvarna washout port quick connect coupling (part #532416405), a two-pack of replacement fittings that let you attach a garden hose directly to your mower deck for under-deck cleaning. Designed for Husqvarna and compatible zero-turn and lawn tractor decks with the factory washout port system.

Fitment & Compatibility

• Check your deck: This fits decks with a pre-installed washout port that uses a 1/4-inch quick-connect male fitting. Not all Husqvarna decks have this—verify you have the port hole and that the existing fitting is the same style.
• Model compatibility: Works on most Husqvarna models from the 2000s onward (e.g., YTH, LTH, Z series) that came with the factory washout port. Also fits some Craftsman, Poulan Pro, and McCulloch decks using the same Husqvarna-made deck system.
• OEM vs aftermarket: This is genuine Husqvarna, so fit and seal are guaranteed. Aftermarket copies often have looser tolerances or different thread pitch (usually 1/4-inch NPT), which can leak or cross-thread.
• Measure before buying: The port hole diameter is roughly 1/2-inch; the fitting threads are 1/4-inch NPT. If your existing port is damaged or missing, measure the hole and thread type carefully.

Key Things to Know

• Installation is easy: Unscrew the old port (may need pliers), apply thread tape or pipe dope to the new one, and hand-tighten plus a quarter turn. No special tools required.
• Seal matters: Use Teflon tape on the threads to prevent leaks. Overtightening can crack the plastic deck housing—snug is enough.
• Common gotcha: The quick-connect coupler on your hose must match. This is a standard 1/4-inch industrial quick-connect, not a garden hose thread. If your hose has a different coupler, you’ll need an adapter.
• Durability: OEM plastic construction is decent but can crack if you drop the mower or hit a rock. The two-pack gives you a spare.

Should You Buy It

Buy this if you own a Husqvarna or compatible deck with a factory washout port and need a direct, no-guesswork replacement. It’s ideal for users who want a quick, clean rinse after mowing and prefer OEM reliability over cheaper aftermarket options that may leak or fail. Skip it if your deck doesn’t have the port or if you’re fine using a standard hose nozzle.
