The TLM seal design, often associated with manufacturers like T-Lon, is known for its durability and performance in heavy-duty applications. 

• Design: It is a compact, double-acting seal suitable for one- or two-piece pistons. The assembly usually includes a primary sealing ring, a rubber energizer (T-shaped or O-ring), and two nylon or other high-strength material anti-extrusion (backup) rings.
• Material: The main seal component is typically a filled Polytetrafluoroethylene (PTFE) compound, chosen for its low friction and high resistance to wear and chemicals. The energizer is often Nitrile Butadiene Rubber (NBR) or an alternative elastomer, while the backup rings are commonly nylon or MoS2 filled polyamide.
• Performance:
  • Max Pressure: Up to 10,000 psi (69 MPa).
  • Max Speed: Up to 5 ft/s (1.5 m/s).
  • Temperature Range: Generally -65°F to 275°F (-54°C to 135°C), depending on the specific material combination.
• Advantages: Reviewers and experts note its low friction (minimizing energy loss), absence of stick-slip (ensuring smooth operation), and long seal life due to the robust materials used. The design can accommodate larger extrusion gaps and performs reliably in both low and high-pressure systems.
