A flange gasket fills the microscopic imperfections in flange faces so the joint holds pressure. Supplementary detail from the product record: NPS, 0.062 THK.

EPDM (EPR) is known for very good flexibility at low temperature, excellent hot water and steam resistance. Expect good resistance to phosphate ester hydraulic fluids, ketones, and ozone, UV and weathering. Exposure to mineral oil-based lubricants or aromatic hydrocarbons will shorten service life.

Maintenance and OEM teams specify it across brake and phosphate ester systems, HVAC and refrigeration, and outdoor equipment.
