SB151 Hydraulic Breaker Diaphragm Membrane Rubber Seal Cup

Our premium SB151 hydraulic breaker diaphragm is a heavy-duty Soosan SB151 rubber membrane and high-performance high-pressure breaker seal cup, serving as a critical SB151 breaker accumulator seal cup for genuine equipment maintenance. Manufactured as a standard OEM SB151 hydraulic breaker seal and robust wear-resistant SB151 rubber diaphragm, this heavy-duty SB151 rubber seal is professionally engineered exclusively for Soosan SB151 and SB150 series hydraulic breakers. It reliably stabilizes internal nitrogen pressure and prevents hydraulic oil leakage, solving common sealing failures during continuous high-frequency impact operations. Constructed with upgraded NBR and PU rubber compounds through precision vulcanization technology, this seal component delivers exceptional resistance against high pressure, abrasion, heat and aging. It stably withstands rigorous working conditions ranging from -35℃ to 135℃ and handles continuous vibration and impact in mining, quarrying, demolition and road construction projects. Manufactured with 100% OEM standard dimensions, this SB151 hydraulic breaker diaphragm ensures a precise, gap-free fit for the SB151 accumulator, effectively eliminating oil seepage, nitrogen loss and reduced striking power caused by inferior sealing performance. Designed as a direct bolt-on replacement, this OEM SB151 hydraulic breaker seal requires no on-site cutting, welding or modification, drastically reducing unplanned equipment downtime and overall maintenance costs. Every wear-resistant SB151 rubber diaphragm undergoes rigorous factory quality testing to ensure consistent, long-lasting and trouble-free performance in harsh working environments.
