MODEL 6351RT: 3-GALLON SLIM DESIGN REPLACEMENT AIR TANK

COMPACT HEAVY-DUTY DESIGN

The Kleinn Model 6351RT is a premium 3-gallon steel replacement air tank engineered with an ultra-slim profile for tight-space installations. Constructed from heavy-duty structural steel with a rugged black epoxy exterior finish, it delivers dependable, high-capacity pneumatic storage where vehicle chassis real estate is at an absolute premium.

ANTI-CORROSION PROTECTION

Internally coated with advanced Cortec™ anti-corrosion protection, the 6351RT safely safeguards against internal rust scaling and moisture contamination to maximize overall system longevity. A precise multi-port configuration provides clean plumbing paths and clean line routing for your compressor feed, pressure switch terminals, main air lines, and accessories.

DIRECT REPLACEMENT FITMENT

Designed as a direct fit for a wide variety of specialized Kleinn systems, the 6351RT seamlessly integrates with VELO-230, VELO-734, VELO-OBA6450, SDKIT-230, SDKIT17-734, and SD17OBA-6450 vehicle-specific systems, as well as the ProBlaster™ HK9-SLIMLINE train horn kit. High-strength vehicle-grade mounting hardware is included for a fast, secure setup.

Why Choose the 6351RT?
