Bailer walls are 1/8" thick Clear FEP, which will not collapse or crack, even after repeated use. Tops are designed to resist weakening where the suspension cord is attached. Bottoms have extra material below the check valve to protect the ball and its seat from scratches, which could result in leaks. Bailers can rest upright with ball seated.
• Quality Assurance - All components are precision machined for exact fit, eliminating costly extra seals. No oils or other lubricants are used in the manufacturing process. All bailers are leak tested, washed in phosphate free detergent and visually inspected prior to shipping.
