Pipe Cap EHB 273/219×6 - Integrally Formed Seal for Water Treatment Equipment

EHB Series Pipe End Caps (273mm/219mm ID, 6mm thick, S30408 stainless steel) are engineered for water treatment high-pressure pipelines, pressure filters and storage tanks. Integrally formed for leak-proof reliability, they offer strong pressure resistance and excellent corrosion resistance, meeting the high-cleanliness and medium erosion-resistant requirements of harsh water treatment sealing scenarios.
