spin-on filters

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.

Note: Spin-on elements are shown with spin-on heads which are available separately.
