Polypropylene (PP) bulkhead fittings are molded tank connectors with internal and external female threads, used to pass fluid through a tank wall while maintaining a secure seal. Available in sizes from 1/2" to 6", these fittings come in standard duty, heavy duty, self-aligning, and anti-vortex styles, with EPDM, FKM, or FPM gaskets. Polypropylene offers strong resistance to acids, bases, salts, and a wider range of solvents than PVC or CPVC, making these fittings a common choice for chemical storage, agricultural chemical tanks, water processing, and general industrial fluid systems. Chemical compatibility and reliable installation make these fittings a practical fit for demanding fluid applications.
