where to buy o-ring for union fitting ?

[fredinstl]

hello

I have a few of those union fittings, and one of the o-ring is bad: B&K 1-1/2 in. PVC SOLVENT Schedule 40 Union 164-637HC - The Home Depot
Where can I find replacement ? I'd like to buy a bag of 10 so I have backups.
is that it: 10-3439 1” Union & 1 1⁄2” Pump Union O-ring (10-PACK) PTK-049 For Hydro Air | eBay ?
I see a few possible items on amazon, but selling by 1, 2 or 3.

thanks !

I have found two solutions.

1) Your local ace hardware typically has lots of 0-rings and have found theme there.
2) get out your handy calipers and measure the o-ring. There are standards for measuring o-rings in the industry. Once I know the number, I just find the best price and order them up!
