Piston seal / hydraulic
Chem-Cast Piston Seals provide flawless sealing at temperatures over 300 degrees Fahrenheit and pressures exceeding 50,000 psi. At the same time, they eliminate hydraulic piston drift, cold flow and metal-to-metal contact. Each seal consists of a self-lubricating, reinforced, heat-stabilized thermoplastic OD sealing ring and an oval elastomeric back-up ring.Chemcast Piston Seals are used in Hyraulic Piston applications. They offer several advantages over conentional o-ring piston seals.
Longer life due to Nylon wear ring.
Higher pressure capability.
Zero leak down drift.
Only one seal needed per piston.
