Oil Level Sight Plugs
The specially designed “bulls eye” prism glass lenses are molded during the hermetic sealing process. The reflective “bulls eye” surfaces reflect light in the absence of any liquid, allowing liquid levels to be seen easily.
The one-piece design is compact and leakproof at high temperatures and pressures. LubeSite oil level sight plugs may be easily installed using pipe thread sealant or left unsealed.
