Question by: Lyle A on Jun 2, 2025, 3:12 PM

Got a cylinder with a 5/8 rod, is this TR-008 the right rod seal size or am I off a hair

Answer by: Customer Support on Jun 4, 2025, 6:40 AM

The key number is rod diameter. TR-008 is sized for a 0.625 inch rod, so it matches a 5/8 inch rod diameter, and it cross-references to Hercules catalog number C1DM44 as a direct replacement.
