O-ring 11x4mm

The 11x4 mm O-ring is a standard sealing component used in high-pressure systems where tightness and resistance to operating conditions are critical. It is commonly applied in pump components, valves, connections, and working accessories of pressure washers.

The seal ensures reliable tightness in joints exposed to high water pressure and frequent duty cycles. The 2 mm cross-section allows stable seating in the groove and reduces the risk of leaks caused by wear or deformation of an old seal.

The 11x4 O-ring is used, among others, in:

• pressure washer pumps
• valves and valve seats
• fittings and adapters
• working accessories

Replacing a worn O-ring is a basic service operation that restores system tightness and prevents further damage caused by leaks.

The product can be used in systems found in Kränzle pressure washers as well as in other devices using seals of this size.
