CHEM CAST PISTON SEALS

CHEM CAST PISTON SEALS

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.

  1. Longer life due to Nylon wear ring.
  2. Higher pressure capability.
  3. Zero leak down drift.
  4. Only one seal needed per piston.
