Product Details

This is a set of 2 aftermarket O-rings for the tip of Karcher high-pressure hoses.

• Photo 1: Actual product
• Photo 2: Karcher genuine hose
• Photo 3: Karcher soft hose
• Photo 4: Reference size
• Photo 5: Currently used unit (K3)

The O-ring at the tip of the hose had deteriorated, causing a water leak, so I used this aftermarket O-ring instead of the genuine product.
The genuine product was expensive and had multiple part numbers, making it difficult to understand, so I chose this one. After replacing it, I have been using it for 2 years without any water leaks (and it is still working without problems).

While this is not a genuine product, it is the same size as the genuine one, so I believe compatibility is not an issue.
However, please refrain from purchasing if you are concerned about aftermarket products.

Before purchasing, please check the shape of your hose tip and consider your purchase.

We also offer the following quantities for those who want to keep spares on hand:

• Set of 3: 540 yen
• Set of 4: 635 yen

If you wish to purchase these, please comment before buying to let us know the desired quantity.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
