701979 O-RING FKM

The 701979 O-RING FKM is a high-quality sealing component supplied by KI Pumps, located in Waukesha, WI. Manufactured by Blackmer, this O-ring is designed for reliable sealing in positive displacement and vane pump applications. Made from FKM (Fluorocarbon rubber), the 701979 O-RING offers excellent chemical resistance, high-temperature tolerance, and superior durability, making it suitable for demanding industrial environments.

Specifications include an outer diameter of approximately 44.5 mm and a cross-sectional thickness of 3 mm, ensuring a precise fit in compatible pump assemblies. The O-ring features a resilient construction with a smooth, elastomeric surface that provides effective sealing against fluids such as hydrocarbons, solvents, and aggressive chemicals. The material’s resistance to heat extends up to 200°C (392°F), while its chemical stability prevents degradation over time, maintaining sealing integrity under continuous operation.

The 701979 O-RING FKM is ideal for use in applications involving hydraulic systems, chemical processing, and fluid transfer where high-temperature and chemical resistance are required. It is a suitable replacement part for Blackmer and other compatible pumps, ensuring minimal leakage and extended service life.

Included in each package is one 701979 O-RING. Not included are any additional pump components or tools. Proper installation requires standard O-ring assembly procedures, including lubrication with compatible sealant if recommended by the manufacturer.

To maintain optimal performance, regularly inspect the O-ring for signs of wear or damage. When necessary, clean with appropriate solvents and replace if deformation or cracking occurs. This O-ring has a standard warranty from the manufacturer, ensuring quality and durability when used within recommended conditions.
