March 0750-0986-1000 O-Ring

The March 0750-0986-1000 Viton O-Ring is a replacement sealing component designed for compatible March magnetic drive pump wet-end assemblies.

Featuring a 0.078-inch cross section and 2.834-inch inside diameter, this O-Ring helps maintain a secure seal between mating pump components and supports dependable fluid containment during operation.

Constructed from Viton material, the seal offers strong resistance to many chemicals, oils, and elevated operating temperatures, making it suitable for a wide range of industrial and chemical-handling applications.

The 0750-0986-1000 is used across several March pump configurations, including compatible AC-5A-MD, AC-5C-MD, BC-4K-MD, BC-4A-MD-AM, TE-5R-MD, and related pump assemblies.

It is ideal for routine wet-end maintenance, preventive servicing, or replacement of a worn, hardened, or damaged O-Ring. Installing the correct seal helps reduce leakage risk and maintain reliable pump operation.

Always confirm your exact pump model and material compatibility before installation.
