All of the O-rings in this assortment have a square profile with flat edges on all four sides. They cover more surface than round-profile O-rings for a better seal in static applications, such as hose, pipe, and faucet connections. They're made of Buna-N, which is resilient and offers excellent tear resistance. They resist hydraulic oils and motor oil. All are sized to the SAE standard AS568.
