Product information

Engineered for performance. Built to last.

Stop wrestling with stiff, kinking hoses and outdated screw fittings. With the help of DTL Lab, CA Detailing has engineered a ground-breaking solution: a fully reinforced rubber replacement hose with a DTL Lab patent-pending proprietary quick connect system, allowing you to convert your Kärcher setup into a seamless, tool-free quick connect system in seconds.

We took the best-selling reinforced hose on the market and made it better — upgrading the fittings, the flexibility, and the finish. This is the hose your pressure washer deserves.


How It Works

Getting set up takes less than a minute:

  1. Wrap PTFE tape around the hose thread endings to ensure a watertight seal, then attach the 3/8" quick connect connector.
  2. Insert the DTL Lab proprietary connector into your Kärcher machine — it clicks firmly into place with no tools required.
  3. Screw the M22–3/8" plug onto your trigger gun until hand-tight.
  4. You're ready. Your hose now connects and disconnects from your trigger gun instantly via the quick connect system.

Key Features

  • Kärcher Compatibility: Engineered to fit most Kärcher K Series machines with yellow-handled guns and Click Bayonet fittings. Please check your hose endings against the product images before purchasing.
  • Patent-Pending Quick Connect System: Our proprietary connector fits 3–8" hose and enables a truly seamless quick connect setup — no tools, no fuss.
  • Reinforced Rubber Construction: 1-ply steel-reinforced rubber hose built for heavy-duty, high-pressure use. Outlasts standard OEM hoses.
  • Anti-Kink Design: Engineered for maximum flexibility without compromising flow. No tangling, no folding — just uninterrupted, consistent water pressure.
  • Multiple Lengths Available: Available from 5m up to 30m. Choose the right length for your setup.
  • 1/4" Internal Diameter: Optimised bore size for strong, consistent high-pressure flow.
  • Please note your original karcher gun will not work with this hose.

Compatibility

✅ Fits newer Kärcher K Series machines with yellow-handled guns

❌ Not compatible with the latest Kärcher machine generation, old non-C clip machines, or Kärcher HD models

Note: Some older non-C clip machines may be convertible using an adaptor — message us to check before ordering.

Note: For lower-powered models (e.g. Kärcher K2), we recommend the 5m–15m options. Hoses of 20m+ may result in reduced pressure output on entry-level machines.


FAQs

Q: Is this hose durable enough for heavy-duty use?

A: Absolutely. The 1-ply steel-reinforced rubber construction is designed to withstand demanding, high-pressure conditions — far exceeding the durability of standard replacement hoses.

Q: How does the anti-kink design work in practice?

A: The reinforced rubber compound maintains structural integrity under pressure, preventing the hose from folding or tangling mid-use. The result is smooth, consistent water flow and a genuinely enjoyable washing experience.

Q: Is it suitable for car detailing?

A: Yes — it's engineered with detailers in mind. The combination of anti-kink flexibility, high-pressure performance, and quick connect convenience makes it ideal for professional and enthusiast detailing alike.

Q: Can I use detergents or snow foam with this hose?

A: Yes. The hose is fully compatible with detergents when used through your Kärcher's existing detergent system. Always ensure any chemical used is rated for high-pressure application.

Q: Will this work with a hose reel?

A: This will work with certain after market reels depending, additional attachments may be required.
