Question by: Chad Y on Dec 30, 2025, 6:27 AM
seal options on this thing got me turned around a bit, we run some pretty aggressive fluids through our system and I wanna make sure I'm picking the right one. what all is available besides the standard buna-n?
Answer by: Customer Support on Dec 31, 2025, 8:50 AM
Beyond the standard Buna-N, you've got four other seal materials to choose from: PTFE, Neoprene, FKM, and Kalrez. For aggressive fluid environments, FKM tends to hold up well and is rated for temperatures up to 400°F, which gives you a solid buffer in demanding conditions. EPDM is another option if your temperature range dips low, as it handles down to -65°F. The right pick really comes down to what specific fluids you're running, but those options give you good coverage across a wide range of chemical and thermal conditions.
