Pressure drops, unexpected leaks, or spraying water? A worn o ring might be the hidden cause behind it all.
A well-matched 고압 세척기 O 링 키트 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.
고압 세척기에서 O링은 어떤 역할을 하나요?
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:
- 퀵커넥트로 인한 마모
- 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.
고압 세척기 O링을 직접 교체할 수 있나요?
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.

고압 세척기에는 어떤 크기의 O링이 필요한가요?
Most washers use 1/4", 3/8", or 1/2" fittings—matched to these o ring specs:
| 피팅 유형 | 내경 | 횡단면 | 재료 |
|---|---|---|---|
| 1/4인치 QC 플러그 | ~6.07mm | 1.78mm(1.78mm) | 비톤 / NBR |

우리의 382 PCS 인치 키트 그리고 428 PCS 미터법 키트 cover all common sizes.
Are Viton o rings better for pressure washers?
Yes—Viton resists heat, pressure, and harsh cleaners.
Standard rubber wears out fast. For hot water washers or degreasers, I recommend our 고온 O 링 키트 for long-lasting durability up to 200°C.

Everything you need for quick repairs across multiple washer types:
