Question by: Rusty W on Sep 1, 2025, 9:23 PM
got a seal marked PSM-326 on the old piston, is this the same one or am i chasin the wrong part
Answer by: Customer Support on Sep 3, 2025, 8:41 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?
Answer by: Customer Support on May 6, 2025, 7:13 AM
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.

Will this Hercules Piston Seal work as a replacement for a C1KW49?
Answer by: Customer Support on May 2, 2025, 7:24 AM
Yes, the PSM-326 is listed as an alternate part number for C1KW49, so it should be a suitable replacement.
