Our filters come with a range of end fittings to suit different housings and applications. End caps are available with a variety of seal materials, including EPDM, Buna-N, Silicone, Viton and FEP Silicone.

Double open-ended (DOE) cartridges usually employ a knife-edge mechanism on both ends of the cartridge with compression to create a seal. They are commonly used for non-critical, general purpose filtration and pre-filtration.
