• MATERIAL SPECIFICATIONS: Manufactured from ABS plastic with precision-formed water outlet holes to produce consistent spray patterns across all cycles. The material is selected for resistance to corrosion and degradation under continuous exposure to water pressure, detergents, and elevated operating temperatures (maximum heat tolerance: 250°F).
