41 Gallon RV Holding Tank - Premium OEM Replacement by Elkhart Plastics
Replace your worn or damaged RV holding tank with this authentic 41 gallon black water holding tank manufactured by Elkhart Plastics/Ameri-Kart. Engineered with precision roto-molding technology and heavy-duty 0.180" wall thickness, this EPI 4327 (H1284) holding tank delivers the same OEM quality and durability as your original equipment.
Measuring 56" x 34" x 7.125", this low-profile holding tank is designed for RVs, travel trailers, and motorhomes where space is at a premium but capacity cannot be compromised. The black polyethylene construction resists corrosion, odors, and UV degradation for years of reliable waste storage.
Why Choose This Elkhart Plastics Holding Tank?
✓ Authentic OEM Manufacturing: Made by Elkhart Plastics/Ameri-Kart, the same manufacturer that supplies major RV brands with original equipment tanks. You're getting factory-grade quality, not an aftermarket imitation.
✓ Heavy-Duty Construction: Precision roto-molded from virgin black polyethylene with a robust 0.180" wall thickness that resists punctures, cracks, and leaks even under the stress of road travel and temperature extremes.
✓ Space-Efficient Design: The 56" x 34" x 7.125" dimensions provide maximum 41-gallon capacity in a low-profile configuration, perfect for tight underbelly installations where vertical clearance is limited.
✓ Verified Compatibility: Direct replacement for EPI part numbers 4327 and H1284. If your existing tank bears either of these numbers, this is your exact match replacement.
✓ Ready to Install: Arrives with standard fittings and mounting provisions. The sealed hole on top is a manufacturing vent (not functional) - all connections are pre-positioned for straightforward installation.
