About Metal End Cap Filters

Metal end cap filters are a cylindrical style cartridge filter, designed for use in harsh environments. They are manufactured from heavy duty materials and can withstand high-temperature environments when made with special potting compounds. Standard construction consists of an expanded or perforated metal core made from carbon or stainless steel. The inner core is encircled by self-supporting paper media or pleated textile media. Textile media is pleated with an epoxy coated steel support screen. Paper medias are typically supported by an outer expanded metal cage. The metal end cap encloses the media and core(s) with a urethane potting compound. Sidco’s metal end cap filters are available in a variety of configurations:

  • open/open style: two open metal end caps
  • open/closed style: one open end cap and one closed end cap with an optional bolt hole.

Metal end cap filters are also referred to as; Metal Ends, Metal Radial End Seals, Radial Fin Filters, Radial Fin Elements, Radial Fin Cartridges, or Air Intake Filters.

Conical filters, dust collectors, skate sharpener filters, and some mist eliminator filters and coalescers are also made with metal end caps.
