Pressure drops, unexpected leaks, or spraying water? A worn o ring might be the hidden cause behind it all.
A well-matched Kit de junta tórica para lavadora a presión 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.
¿Qué función tiene una junta tórica en una hidrolavadora?
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:
- Abrasión por conexiones rápidas
- 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.
¿Puedo reemplazar las juntas tóricas de la hidrolavadora yo mismo?
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.

¿Qué tamaño de juntas tóricas necesito para una hidrolavadora?
Most washers use 1/4", 3/8", or 1/2" fittings—matched to these o ring specs:
| Tipo de ajuste | Diámetro interior | Sección transversal | Material |
|---|---|---|---|
| Enchufe de conexión rápida de 1/4" | ~6,07 milímetros | 1,78 milímetros | Vitón/NBR |
| Acoplador de conexión rápida de 3/8" | ~9,25 milímetros | 2,62 milímetros | Vitón/NBR |
| Sellos de bomba de 1/2" | 10–14 milímetros | 3,5 milímetros | Vitón/NBR |

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 Kit de juntas tóricas para alta temperatura for long-lasting durability up to 200°C.
