Purolator invented the spin-on filter and continues to lead the industry today.  Our industrial spin-on filters are designed to provide superior filtration performance and convenience.  They will fit most existing spin-on heads and are readily interchangeable with most competitive filters.  We also offer a full range of die-cast aluminum heads and gauges.
