NAUGATUCK GRT45S421C Stainless Steel Through-Tube Float Ball

A NAUGATUCK tubed float ball is used as a liquid level sensor in tanks, reservoirs, and industrial process vessels. Its through-tube design allows it to slide along a guide rod or stem, triggering switches or valves at preset levels in water, oil, and chemical applications.

The NAUGATUCK GRT45S421C is a stainless steel cylindrical float ball with a 1/2 in through-tube design and 1/2 in thread size. It is suitable for use in corrosive environments and high-temperature fluids up to 850 °C, depending on the stem assembly.

Slide the NAUGATUCK float ball onto a clean, straight guide rod or stem of matching 1/2 in diameter. Secure the rod at both ends to prevent lateral movement. Ensure the float moves freely along the rod without binding. Follow the stem manufacturer's wiring and mounting instructions for reliable level switching.
