70A Nitrile Square Rings feature a flat-edged profile that provides increased sealing surface area compared with standard round O-rings. Designed primarily for static applications such as hose, pipe, and faucet connections, these rings provide excellent tear resistance and durable sealing performance. The nitrile construction resists hydraulic oils and motor oil, while standard O-ring dash-number sizing supports easy identification and compatibility.
