got a seal marked PSM-326 on the old piston, is this the same one or am i chasin the wrong part

Question by: Rusty W on Sep 1, 2025, 9:23 PM

Match-up is straightforward here since the supplier part number for this seal is PSM-326. It also crosses to alternate part number C1KW49. If your old seal is marked PSM-326, it lines up with this Hercules Sealing Products piston seal.

Got a piece of equipment that calls out part number C1KW49 for the piston seal, is that the same thing as the PSM-326?

Question by: Warren G on May 4, 2025, 2:15 PM

Same part. C1KW49 is just an alternate part number that cross-references to the PSM-326 from Hercules Sealing Products. If your equipment documentation or an old parts list shows C1KW49, you're looking at the right seal.
