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?

  • Cortec™ Lining: Premium internal anti-corrosion layer shields the tank from moisture rust and internal scaling.
  • Slimline Footprint: Elongated, slender design engineered specifically to clear tight chassis frame rails and narrow under-body voids.
  • 6-Port Architecture: Equipped with five 1/4" NPT ports and one 3/8" NPT port to handle optimized high-flow plumbing configurations.
  • Epoxy Armor: Rugged structural steel construction wrapped in a durable gloss black exterior epoxy powder coating to withstand road-debris abuse.
  • Perfect Application Fit: Built explicitly as the official factory drop-in matching replacement tank component for Kleinn slim-profile air systems.

THE VERDICT: The ultimate space-saving replacement air reservoir for narrow footprints. The Model 6351RT restores original 3.0-gallon storage capacity and premium internal safety linings without sacrificing valuable vehicle clearance paths.
