Pressure drops, unexpected leaks, or spraying water? A worn o ring might be the hidden cause behind it all.
A well-matched sada tlakových myček nebo kroužků 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.
Co dělá O-kroužek v tlakové myčce?
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:
- Oděr od rychlospojek
- 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.
Mohu si tlakovou myčku nebo kroužky vyměnit sám?
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.

Jakou velikost kroužků potřebuji pro tlakovou myčku?
Most washers use 1/4", 3/8", or 1/2" fittings—matched to these o ring specs:
Typ kování | Vnitřní průměr | Průřez | Materiál |
---|---|---|---|
1/4" QC zástrčka | ~6,07 mm | 1,78 mm | Viton / NBR |
3/8" QC spojka | ~9,25 mm | 2,62 mm | Viton / NBR |
1/2" těsnění čerpadla | 10–14 mm | 3,5 mm | Viton / NBR |
Náš Sada 382 ks palců a Metrická sada 428 ks 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 Sada vysokoteplotních O kroužků 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:
Typ sady | Norma | Velikosti | Průřezy | Materiály | Nejlepší pro |
---|---|---|---|---|---|
Sada 382 ks palců | SAE | 30 | 1,78–5,33 mm | NBR / Viton | U.S. models |
428 KS metrický | ISO/DIN | 30 | 1,50–3,00 mm | NBR / Viton | EU/Asia washers |
OEM Custom Kits | Žádný | Zvyk | Žádný | Viton / PTFE | Distributors, OEM |
