Zoro Select Buna-N O-Ring Dash 215 Pack of 50

This pack contains fifty black Buna-N O-rings sized to Dash 215 with a rectangular cross-section. They are designed for static sealing applications where oil and fuel resistance are required. The material carries FDA approval for incidental food contact.

Sustained temperature performance from -40 to 250

The 70A durometer compound maintains sealing force across the full rated range of -40 to 250 degrees F without rapid compression set. Metal-detectable particles allow contamination control in food or pharmaceutical lines. The seals are not X-ray detectable.

Check groove dimensions

Verify that the gland matches the actual inside diameter of 1 inch and actual width of 0.139 inch. Confirm that the media is compatible with Buna-N; the material is unsuitable for phosphate esters, ketones, or strong ozone exposure.
