Do harnesses expire?


New member
I'm buying/getting a few older harnesses from some members on here. What are the expiration dates on Graco harnesses? They only have the DOM on them, not the expiration date.

Depends on the expiration date of the particular seat, but I would go with that.

So if a seat has a six year expiry, then assume the harness does as well?

I'm talking the GN. It has, what, a 6 year expiry for harness? 10 for HBB, 9 for LBB?

If it has a 6-year expiry, then assume the same for the harness. I honestly don't remember the Nauti's expiration (and maybe it changed at some point?) other than it being less in harness mode vs booster.

That's what I assumed, though I was hoping you'd have a magical answer that I'd like a bit more. :p

The old ones had a 6 year on the back, harness or not. The new ones are ten all around. So for old harnesses I'd say 6 from the SEAT'S dom (not harness.)
