Got a cylinder on a log splitter that's been weeping around the gland seal for a while now, the old o-ring measures out to about 3.86 on the inner diameter. This the right part to swap in?

For a -241 dash number o-ring, 3.859 inches inner diameter with a 0.139-inch cross-section is exactly the spec, so that measurement lines up. Nitrile is a solid choice for hydraulic cylinder gland seals running petroleum-based fluid, which covers most log splitter setups. As long as your groove is cut for a -241, this one should drop right in as a replacement.

trying to swap out an old seal, is this one the -241 o-ring with 3.859 inch ID and a 0.139 cross section?

Match the dash number and the two dimensions. This is a -241 size O-ring with a 3.859 inch inner diameter and a 0.139 inch cross-section, so it lines up with standard -241 sizing for replacement or cross-referencing.
