3/4 SQUARE BUNA 70 O-RING CORD

The 0296750 is a black Buna-N (Nitrile) 70 Shore A Square-Cut Cord Stock built to a cross section of 0.75 in (19.05 mm). This square-cut cord stock ships as continuous square-cut stock so a custom-length seal can be cut and spliced on site.

Buna-N (Nitrile) is specified here for economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. The material holds up against propane and butane, water, and many alcohols. It should not be specified for service in polar solvents or strong acids. The profile itself contributes a rectangular section that will not roll in the groove and simple lathe-cut manufacture at low tooling cost. Note that a square section is less suited to high-speed rotary service, where the larger contact area raises friction and heat.

You will find this material specified across general industrial maintenance, automotive, and fluid power.
