A Buna-N O-ring helps form a large sealing barrier between compatible components, and this generic version features a 16-1/8 inch inside diameter and 7/16 inch cross section using the O-100 reference. Larger O-rings like this are useful in equipment applications where broader sealing surfaces need a flexible, serviceable seal.

This part has practical value because dimension-based identification makes it easier to confirm fit when servicing large lids, housings, or tank-style assemblies. A properly matched Buna-N O-ring helps restore the intended seal and contributes to more dependable leak prevention in larger equipment joints.

This type of part is especially useful when the original large-diameter seal has flattened, cracked, or lost the elasticity needed to maintain pressure evenly across the joint. That helps restore the sealing surface without replacing the surrounding assembly.

Installed in the proper application, this Buna-N O-ring helps support dependable large-joint sealing and more confident maintenance outcomes.

  • Uses the O-100 reference
  • Helps seal larger compatible housings or connection points
  • Useful when replacing a worn or flattened large-diameter seal
