Airlock need after racking to secondary

[olstones]

I am making a belgian strong ale this weekend.
I am planning to moving to a secondary after 2 weeks of fermentation and let it sit for at least 2 months.

Normally I rack to secondary for dry hopping or clearing out some of the sediment and leave it secondary for a week max. In these cases I have always had an airlock on.

So if I want to let the beer condition for months, would I still add an airlock or just seal it and store?

Any insight is appreciated

I would use one, in case there's some residual sugars the'll munch on. Never really hurts to have one.

These work well for long term aging?

Thanks, that looks like a great idea!
