The 70 gallon Elkhart Plastics fresh water tank measures 77 5/8" x 20" x 11" with a tank wall thickness of approximately 0.180". For fittings, the standard options include 2-inch and 3-inch sizes compatible with gate valves. While the tank is designed to accept Uniseal type fittings, their effectiveness depends on the tank wall thickness and material. At 0.180", Uniseals can provide a reliable, compression-based seal for 2-inch fittings, but caution is advised for the larger 3-inch drain due to the thinner wall.

Elkhart RV Parts does not currently offer custom spinweld installation services for these fittings. However, you can purchase the Universal Fitting Kit, which allows a DIY installation of fittings exactly where needed without compromising the tank integrity. This kit has received positive feedback regarding its sealing performance.

For customers desiring professional installation, the Custom Fittings Install Service is available as a special order at $208.33, which includes spinweld installation of up to five parts. Please note this service requires direct contact with customer service for ordering.

If you are experiencing issues completing your online purchase due to the tank being marked as special order, please contact customer service for assistance with order confirmation and processing.
