Secure your pump housing firmly to the motor frame and maintain proper alignment across internal seals. These heavy-duty factory bolts fasten the seal plate motor bracket directly to the C-face motor flange. Over years of operation, outdoor exposure, chemical corrosion, or over-tightening can rust, strip, or shear original mounting hardware. Replacing worn hardware with this corrosion-resistant OEM bolt set prevents housing flex, protects shaft alignment, and ensures tight seal compression under pressure.
