Question by: Freddie W on Sep 29, 2025, 7:46 AM
seal options on this one got me curious, we run some pretty aggressive hydraulic fluid and buna-n ain't always gonna cut it. what else does this swivel come in?
Answer by: Customer Support on Sep 30, 2025, 7:04 PM
Viton is available on this joint, which handles a broader range of aggressive fluids a lot better than standard Buna-N. There's also an EPR option if your application calls for it. The suffix on the part number tells you which seal you've got, -01 is Buna-N, -04 is EPR, and -06 is Viton. The part number on this listing ends in -06, so that one ships with Viton seals already.
