Small diameter sock that lets you know if there's oil in your monitoring well.
  • Rigid polypropylene case keeps small-diameter sock in direct contact with liquids at all times for maximum efficiency
  • Design prevents bunching or bending when lowered into spaces as tight as 2" wide
  • Perfect for soaking up unwanted oil-based fluids that collect in monitoring wells, tanks, bilges, underground substations, stormwater drains and other limited-access applications
  • End caps feature tie-off eyelets for rope and weight (not included); use sock, then attach rope to other eyelet and reuse
  • Large apertures in casing allow oil to easily pass through to the absorbent sock without blinding like smaller-aperture cases
  • Absorbs and retains oils and oil-based liquids - including lubricants and fuels - without taking in a drop of water
  • Bright white color makes absorbed oil easier to see; clearly shows saturation level
  • Can be incinerated after use to reduce waste or for fuels blending
