these stretch to fit over the o-ring groove, or do they go in separate before the o-ring gets seated?
Question by: Rusty B on Mar 27, 2025, 2:26 PM
Urethane back-up rings like these are molded to be stretched during installation, then they snap back to their original size once in place. That return to shape is what makes them sit correctly in the groove alongside the o-ring. Sizing on these corresponds directly to o-ring sizes, so matching your dash size is how you get the right fit.

What's the deal with the quantity? Is that price for just one ring or the whole pack?

Good question. Price shown is per individual back-up ring, not the package of seven.

That's how they work. The urethane material lets you stretch them over the groove or fitting during installation, and they return to their original dimensions once in place. Makes the whole process a lot less of a headache compared to stiffer materials.
