Product Overview:
The 302 is a face-to-face double rotary cartridge seal specifically designed for hazardous and aggressive sealing applications in the chemical and process industries. It incorporates a patented pumping action to maintain cool running, which reduces wear and prolongs seal life. The double balanced design allows the seal to accommodate up to 30 bar (440 psi) of product or barrier pressure, making it suitable for demanding industrial operations. Constructed from high-quality corrosion-resistant materials, the 302 ensures reliable operation in chemically aggressive or high-pressure environments. Depending on condition, all First4Seals cartridge seals can be fully refurbished.
