A blocked line changes the job. Cleaning nozzles need water to flow past them to work; when a line is packed with roots, grease, sand or collapsed debris, you first need a nozzle whose whole design is forward — punching a path so water (and then a cleaning nozzle) can follow. That's the penetrating family. KEG makes four, and they're not interchangeable.
The four penetrators, compared
| Nozzle | Front end | Built for | Sizes |
|---|---|---|---|
| Rambo | Wedge shape + drill point + forward jet | The hardest hits in the family — KEG calls it the best penetrating nozzle in the industry. Packed blockages, roots, compacted debris. | 1/4"–1-1/4" |
| Triple Edge Quattro | 4 forward jets + sharp edges | Total blockages in deformed or misshapen pipe; sand, mud, roots, trash. | 1/4"–1-1/4" |
| Drill Point Quattro | Stainless drill tip w/ 3 jets | Total blockages where grease is the culprit; the drill point is replaceable. | 1/4"–1" |
| Egg Devastator | 4 forward + 3 rear at 30° | Blockage-busting with cleanup behind it — the rounded 300-series stainless body follows through the opening it makes. | 3/8"–1-1/4" |
How to pick
- Roots or unknown hard blockage: Rambo. The wedge concentrates the machine's power on a point; once it's through, the rear jets pull debris back.
- Grease plug: Drill Point Quattro — the drill tip bores the grease while rear jets keep the nozzle moving.
- Deformed/offset pipe where a round nozzle hangs up: Triple Edge Quattro — the edged profile works through irregular openings.
- Want penetration + cleaning in one trip: Egg Devastator — it opens the line and its rear jets wash behind it.
After the breakthrough: a penetrator opens a path, it doesn't finish the pipe. Follow with a Cleaning Nozzle for the wall, and a Rotor if a camera is going in after.
Construction notes
Small sizes (1/4"–3/8" Rambo and Quattro, up to 1/2" on some models) are factory-drilled; from 1/2"–3/4" up they run replaceable threaded inserts in steel (-S) or titanium ceramic (-C). The Rambo's drill point is removable — on 1/2" and larger a standard M8 insert can take its place, turning it into a straight thruster. Per KEG's spec text the Rambo rates as a cost-competitive Tier Two nozzle in 3/4"+ sizes; the Quattros rate Tier One–Two depending on size. Penetration is about concentrated force, not wall-cleaning efficiency — pick tier-rated nozzles for the cleaning pass (how tiers work).
