Alpha 40 Gallon RV Holding Tank - VB24637HL

Upgrade your RV's waste management system with the Alpha VB24637HL, a premium 40-gallon holding tank engineered to meet or exceed OEM standards. This rotational molded tank features extra-durable one-piece construction, rigorous leak testing, and superior durability that outlasts factory-installed tanks. With low-profile dimensions of 63" x 25" x 7", this tank maximizes capacity while fitting in tight vertical spaces.

Why Choose the Alpha VB24637HL Holding Tank?

Extra-Durable Rotational Molded Construction

Engineered with heavy-duty rotational molding, the VB24637HL features seamless one-piece construction that eliminates weak points and potential failure areas. This superior manufacturing process creates a tank that's significantly stronger and more durable than typical factory-installed holding tanks.

Rigorous Leak Testing for Peace of Mind

Every Alpha VB24637HL is individually submerged and pressure-tested for leaks before shipping. This comprehensive quality control ensures your tank is 100% leak-proof from day one, giving you confidence that your RV's waste management system will perform flawlessly.

NSF Certified for Safety and Quality

Built to meet or exceed NSF certification standards for RV waste management, the VB24637HL is designed to safely contain black water and gray water waste. The durable construction resists odors, stains, and degradation even after years of use.

Low-Profile Design for Tight Spaces

With just 7 inches of height, this 40-gallon tank is perfect for installations where vertical clearance is limited. The elongated 63" x 25" footprint provides generous capacity while fitting into narrow compartment spaces.

Built for the RV Lifestyle

Designed to withstand the constant movement, vibration, and temperature changes that come with RV travel, this tank maintains its integrity mile after mile. The robust construction ensures reliable performance whether you're boondocking in the desert or camping in freezing temperatures.
