Description

The 711938 O-RING FKM by Blackmer is a high-quality sealing component designed for demanding industrial applications. Manufactured from FKM (fluorocarbon rubber), this O-ring offers excellent chemical resistance, high temperature tolerance up to 200°C (392°F), and outstanding durability, making it suitable for sealing tasks involving aggressive fluids and high-pressure conditions. Its reliable sealing performance is critical in maintaining the integrity of pump systems, especially in environments with exposure to oils, solvents, and other chemicals. 

The 711938 O-RING features a standard internal diameter of approximately 48.00 mm (1.89 inches) and a cross-sectional width of about 3.53 mm (0.139 inches), ensuring compatibility with various Blackmer pump models and related machinery. Its robust construction from FKM provides chemical compatibility with a wide range of industrial fluids, including hydrochloric acid, brake fluids, and synthetic oils, while maintaining flexibility over a broad temperature spectrum.

Specific features of the 711938 O-RING include:

  • Manufactured from FKM (fluorocarbon rubber) for chemical and temperature resistance
  • Standard size with an internal diameter of approximately 48 mm and cross-section of 3.53 mm
  • Designed for use in sealing connections within positive displacement pumps and sliding vane pumps
  • Resistant to oil, fuel, and aggressive chemicals commonly encountered in industrial environments
  • High resilience to compression set and extrusion, ensuring long service life

The 711938 O-RING FKM is ideal for use in water treatment, chemical processing, and oil & gas industries, especially in applications requiring reliable seals under high-temperature and chemically harsh conditions. It is suitable for maintenance and replacement in Blackmer pump models and other industrial systems that utilize FKM sealing components.

Each package includes one 711938 O-RING. Not included are additional sealing accessories or specific installation tools, which are typically provided separately by the equipment manufacturer.
