Water Tank Sensor Probes Constructed of stainless steel and combined with durable vulcanized rubber grommets and rust-resistant hardware, these button-head sensors are built to last in the harsh environment of your substrates while being continually exposed to gray, black, and potable water. Sensor – grommet (1), button-head sensor post (1), washer (1), 3/8” nut (2) Vulcanized grommet Rust-resistant post and hardware Collapsing pressure system guarantees virtually impenetrable seal if properly installed For use with RecPro water tank gauge systems.

• Made in USA - These reliable little sensors were made in the USA, so you know you’re getting a high-quality product that was made with you in mind. These sensors are durable and are sure to last.
• Rust resistant - The materials for the sensor are made up of a combination of stainless steel and rubber. So these sensors will stand up to the rigors of use without rusting and corroding for long-lasting reliability.
• Vulcanized grommet - The grommet is made of vulcanized rubber. The vulcanization process makes rubber less porous and stronger. So when this probe is installed properly, the pressure seal created by the grommet is impenetrable.
