Solid Connection
No more leaks between your washer and foam cannon
A generic adaptor that weeps under pressure defeats the entire purpose of a quality foam cannon. The MJJC Karcher K Series connector uses a precision-machined brass threaded insert seated in a reinforced polymer body to give you a firm, leak-free coupling every time you press the trigger.
Why It Works
Designed for the job, not just the sale
Four reasons this connector earns its place in your kit.
-
Leak-Free Under Pressure
Precision-machined brass threading seals completely, so no pressure bleeds off between washer and cannon.
-
Instant Hand-Tight Fit
Tightens and releases by hand in seconds - no tools, no struggle, even with wet gloves on.
-
Corrosion-Resistant Build
Brass insert and heavy-duty polymer body hold up against continuous water and chemical exposure.
-
K Series Specific
Engineered to match the K Series port exactly, not a one-size-fits-all guess that half-works.
MJJC vs Generic
Not all adaptors are the same
Generic connectors look similar in a product photo, but the difference shows up the moment you open the trigger. Here is how the MJJC Karcher K Series connector stacks up against a typical no-name alternative.
| Feature | DetailerSA | Alternative |
|---|---|---|
| Precision-machined brass threaded insert | Yes | No |
| Reinforced heavy-duty polymer body | Yes | No |
| Leak-free seal at full operating pressure | Yes | No |
| Compatible with standard foam cannons | Yes | Yes |
| Fits Karcher K Series port | Yes | Yes |
| No tools required for installation | Yes | No |
Built to Last
Corrosion-resistant materials that handle regular use
Wash after wash, the brass insert and heavy-duty polymer body resist the moisture, chemical splashback and UV exposure that come with detailing. Compact enough to tuck into any kit bag, this connector is a permanent addition to your setup rather than a consumable you keep replacing.

Questions
Frequently asked
Which Karcher models is this connector compatible with?
This connector is specifically designed for the Karcher K Series range of pressure washers. If you own a K2, K3, K4, K5, K6 or K7 model, this adapter is built to fit the standard K Series lance port. If you are unsure about your specific model, check your Karcher's outlet fitting type before ordering.
Does this connector fit any foam cannon, or only specific brands?
It is compatible with most standard foam cannons and snow foam lances on the market, including popular aftermarket options. The dual-port design accommodates the most common thread sizes used across foam cannon brands. MJJC's own foam cannons are a natural pairing, but the connector is not limited to them.
Will this connector cause any pressure loss during foaming?
No. The precision-machined brass threaded insert creates a leak-free seal that maintains full operating pressure from the washer through to the foam cannon. A poor-quality generic connector is usually where pressure loss originates, so the machined brass insert here is the critical detail.
Do I need any tools to install or remove it?
No tools are needed. The connector is designed for easy hand-tightening, so you can attach or swap it between foam cannons quickly, even mid-job with wet hands. Just ensure you tighten it firmly to achieve a proper seal.
Is the connector safe to leave outdoors or in a wet environment?
Yes. The materials are corrosion-resistant - the brass insert resists oxidation and the heavy-duty polymer body handles moisture and UV exposure without degrading. That said, rinsing and storing it dry after use will extend its service life.
Can I use this connector with a snow foam lance for pre-wash decon?
Absolutely. The connector works equally well with snow foam lances as it does with foam cannons. Run your decon foam, rinse, then swap to your rinse lance without any adaptor changes - the dual-port design gives you that flexibility.
How do I know if I have a genuine MJJC connector or a generic copy?
Genuine MJJC connectors feature consistent machining on the brass insert and clean, uniform polymer moulding. Counterfeits tend to have rough thread edges and uneven body seams. Purchasing from an authorised South African stockist like Detailer SA is the straightforward way to ensure you are getting the real product.
Does this connector come with any washers or O-rings for the seal?
The source description does not specify included O-rings. The brass threaded insert is precision-machined to form the seal on its own. If your foam cannon's own inlet includes an O-ring, that will seat correctly against the brass thread for an additional leak barrier.
