Repair Kit - Seals for Large Handheld Foam Herbicide Dispenser
This kit contains all you need to replace the seals on the Large Handheld. The kit includes 5 O-rings; 1 umbrella valve; 1 strainer; and on pouch of silicone grease. These seals are made from nitrile rubber (chemical name: Butadiene Acrylonitrile). We deliberately chose this material for the replacement seals because it expands less when exposed water-based solutions.
