Pressure drops, unexpected leaks, or spraying water? A worn o ring might be the hidden cause behind it all.

A well-matched 高圧洗浄機 O リング キット restores sealing performance, keeping every connection watertight and efficient.

I’ll walk you through why o rings matter, how to replace them, and which kit works best for your washer brand and fittings.

高圧洗浄機の O リングは何をするのですか?

It seals hose ends, nozzles, and quick-connects to prevent high-pressure leaks.

O rings create a watertight barrier in trigger guns, pumps, hoses, and nozzles. Without them, pressure drops quickly and water escapes—damaging parts and reducing cleaning performance.

Why do o rings fail in pressure washers?

Heat, chemicals, and vibration wear them out over time.

Common issues include:

• クイックコネクトによる摩耗
• Chemical damage from detergents
• Incompatibility with hot water units
• Compression fatigue from high PSI cycles

For best results, I always keep a pressure washer o ring assortment kit ready.

高圧洗浄機のOリングを自分で交換できますか?

Yes—it takes 10–15 minutes with a pick tool and the right kit.

I use a flathead or hook tool and lubricant to swap out damaged o rings. With standardized SAE and ISO sizes, replacement is simple and cost-effective.
