SAE adapter flange for S3/S3H gauge Wema

The Wema FL-2 adapter flange is an essential component for installing a level sensor in a tank without a suitable threaded opening. It enables the transition from a 5-hole SAE standard to Wema S3, S3H, or S5 sensors with a 1 1/4″ thread. In doing so, it ensures perfect compatibility between the tank and the gauge.

Designed for demanding marine and sanitary environments, this flange is made from durable, corrosion-resistant materials. The stainless steel provides excellent long-term durability, particularly against moisture, black water, and fermentation gases. In addition, the nitrile gasket enhances sealing performance and resists hydrocarbons and chemicals commonly found in wastewater systems.

Its mounting system is especially practical. The inner ring allows installation without internal access to the tank. Furthermore, the stainless steel fasteners ensure secure and long-lasting tightening, even in harsh conditions. Overall, the kit guarantees optimal sealing and reduces the risk of leaks or odors.

This solution is ideal for black water tanks on boats or leisure vehicles. It simplifies the installation of level sensors, avoids unreliable DIY adaptations, and improves the system’s long-term reliability.
