SP-SPARE SEALS KARCHER (HD-6/15-4)-KA-33

The Kärcher Spare Seals Kit (reference KA 33) is an essential pump maintenance set designed specifically for the HD 6/15-4 Classic high-pressure cleaner (and compatible models like HD 5/17 C or HD 6/15 C). This kit addresses common issues like low pressure, leaks, or reduced performance caused by worn or aged seals in the axial piston pump. It includes a comprehensive selection of replacement parts for straightforward DIY or professional servicing, ensuring optimal pump efficiency and extending the machine's lifespan. Ideal for regular maintenance (recommended every 12 months), it restores full pressure output up to 15 bar and flow rates of 600 l/h.

Key Features:

• Component Breakdown: Contains critical spares such as lip seals (low- and high-pressure), O-rings, support washers, grooved rings (water and oil sides), drain plugs, bushes, and valves—typically 10-15 pieces for complete seal replacement.
• Compatibility: Tailored for Kärcher HD series pumps (e.g., K45 or similar axial types in HD 6/15-4); verify fit via machine serial number or part code 4.762-059.0 (or equivalent).
• Durability and Material: High-quality, wear-resistant rubber and polymer seals engineered for high-pressure environments, resistant to water, oil, and abrasion for reliable long-term performance.
• Ease of Installation: Service manuals guide seal replacement in under 1 hour; wide machine cover on HD models provides easy access without disassembly.
• Benefits: Prevents leaks, maintains pressure consistency, and reduces downtime; promotes eco-friendly operation by avoiding full pump replacements.

Ideal For:

Professional cleaners, contractors, or facility managers maintaining cold-water high-pressure washers for tasks like vehicle washing, surface cleaning, or industrial degreasing. Not for hot-water (HDS) models—use dedicated kits. Users report it effectively cures pressure drops, with 4.7+ ratings for value and simplicity in restoring performance.
