Currently, our custom spinweld fitting installation service is temporarily unavailable as we are improving it for future availability. However, you can purchase individual fittings separately, including 1/2" NPT threaded fittings compatible with 1/2" hose barb connections, which are common for fresh water tanks. We recommend using our Universal Fresh Water Tank Fittings Kit, which includes all necessary components and detailed installation instructions to help ensure a secure, leak-free setup. The kit uses durable grommets designed to maintain a tight seal under water pressure without requiring specialized tools. For step-by-step guidance, please refer to our installation PDF guide available on our website. If you prefer to replicate your original tank fittings layout, using 1/2" Uniseal grommets combined with standard 1/2" NPT threaded fittings is an effective solution that balances durability and ease of installation.
