Question by: Darryl C on Jun 22, 2025, 9:57 AM
got a hose reel that needs to spin without twisting the line. is this FS65 swivel the kind that’ll rotate all the way around?
Answer by: Customer Support on Jun 24, 2025, 9:21 AM
For setups where the line needs to turn freely, the FS65 is built for 360° rotation and uses a balanced pressure design to keep the swivel action consistent.
Question by: Patty S on Nov 29, 2025, 11:31 AM
seals on this thing, what are my options if buna-n ain't gonna cut it for what I'm running?
Answer by: Customer Support on Nov 30, 2025, 5:38 PM
Two other seal materials are available for this swivel joint. EPR is the suffix -04 option, and Viton is the suffix -06 option. Buna-N comes standard on the -01 suffix version. All three are rated down to -40 degrees C on the low end, so the cold side isn't where they differ. The choice really comes down to fluid compatibility with whatever media you're pushing through the line. A fluid compatibility reference document is available through Eaton's published resources if you need to cross-check a specific fluid against seal material.
Question by: Hubert G on Sep 11, 2025, 7:19 AM
Reckon this swivel joint will hold up alright for a hydraulic setup running around 3500 PSI? Don't want no leaks.
Answer by: Customer Support on Sep 12, 2025, 9:14 AM
It's rated to handle 3500 PSI in the 1/2 and 5/8 sizes, so you should be good to go there, provided you're using the right size. Also, make sure you get the right seal material, depending on the fluid you are using. Buna-N is standard, but EPR or Viton are available if needed.
