AROCLOR 1248 Chemical compatibility with O-rings, rubbers, & plastics

Aroclor 1248, also known as PCB-1248 or polychlorinated biphenyl 1248, is a chlorinated aromatic compound historically used in transformers, capacitors, hydraulic fluids, and as a plasticizer. As part of the PCB family, Aroclor 1248 is a persistent organic pollutant associated with carcinogenic and endocrine risks. When reviewing chemical compatibility for O-rings, rubber seals, gaskets, and plastic components, careful material selection is critical due to potential swelling or degradation. Proper containment, handling, and disposal procedures are essential to prevent contamination and protect sealing performance.
