This black Buna-N 343 quad ring is a four-lobed sealing component for maintenance and repair professionals working with compatible fluid-sealing assemblies. Its X-ring profile is designed for applications requiring a compact elastomer seal.

The ring has a 3-3/4 in. inside diameter and a 4-1/8 in. outside diameter. It is black, round, and rated at 70 durometer. Buna-N, also called nitrile or NBR, is noted in the source material for resistance to petroleum-based fuels and lubricants.

Key Features:

  • Quad-ring profile: Provides a four-lobed X-ring sealing form for compatible assemblies.
  • Buna-N elastomer: Offers resistance to petroleum-based fuels and lubricants described for nitrile material.
  • Defined ring dimensions: The 3-3/4 in. ID and 4-1/8 in. OD help buyers match the ring to required fit dimensions.
  • Effective minimum order: A minimum order quantity of 8 applies.

Choose this 70-durometer Buna-N quad ring when its 343 profile, black finish, and stated inside and outside diameters match the requirements of your sealing application.
