A double piston seal is a type of sealing arrangement designed
for hydraulic cylinders and systems. It consists of two separate sealing elements that are stacked or arranged in tandem to provide enhanced sealing performance. The primary purpose of a double piston seal is to prevent the leakage of hydraulic fluid between the piston and cylinder bore, ensuring the efficient operation and longevity of the hydraulic system. Here we will explore about double piston seal profiles –
