Pressure drops, unexpected leaks, or spraying water? A worn o ring might be the hidden cause behind it all.
A well-matched kit de anel de vedação para lavadora de alta pressão 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.
O que um anel de vedação faz em uma lavadora de alta pressão?
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:
- Abrasão por conexões 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.
Posso substituir os anéis de vedação da lavadora de alta pressão sozinho?
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.

Qual tamanho de anéis de vedação eu preciso para uma lavadora de alta pressão?
Most washers use 1/4", 3/8", or 1/2" fittings—matched to these o ring specs:
| Tipo de encaixe | Diâmetro interno | Corte transversal | Material |
|---|---|---|---|
| Plugue QC de 1/4" | ~6,07 milímetros | 1,78 milímetros | Viton / NBR |
| Acoplador QC de 3/8" | ~9,25 milímetros | 2,62 milímetros | Viton / NBR |
| Selos de bomba de 1/2" | 10–14 milímetros | 3,5 milímetros | Viton / NBR |
Nosso Kit de 382 polegadas e Kit métrico 428 PCS 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 Kit de anel O de alta temperatura for long-lasting durability up to 200°C.
What’s included in your o ring kit?
Everything you need for quick repairs across multiple washer types:
| Tipo de kit | Padrão | Tamanhos | Seções Transversais | Materiais | Melhor para |
