High-Performance Jetter Truck
GapVax GJETJetter truck
GapVax took everything that makes its combination truck great and applied it to a more affordable, high-performance jetter truck: a stainless steel tank, the smoothest water pump system with multi-flow and recirculation, plus added storage and useful controls.
Built like the combo truck

Simple
Simplicity and reliability are the hallmark of GapVax. The time-tested front-mounted hose reel gives you strength, simplicity and a user-focused design that just keeps running.

Safety
The hose reel rides on dual frame rails that extend past the engine. Baffles guard against tipping with a full load, safety interlocks help prevent operator error, and the front-mounted reel guards against traffic.

Storage vs capacity
We help you find the right blend of storage and water capacity while watching axle weights. Models run from 1,000 to 3,000 gallons; most customers choose 1,600 gallons on a single axle.

What the warranty covers
GapVax warrants the GJET jetter truck against defects in materials and workmanship for one year from delivery. Jet Line is your GapVax service location and files every claim for you.
Chassis is covered by the chassis manufacturer’s own warranty. GapVax completes the chassis warranty registration before the truck ships, so coverage is in place on day one. Freight on warranty parts is the buyer’s.
