does this thing come with the o-ring and bolts, or do i gotta source those separate?

Answer by: Customer Support on Apr 15, 2025, 4:46 PM

Everything you need to make the connection comes in the box. Mounting bolts, lock washers, and a Buna-N O-ring are all included with the adapter, so you're not hunting down hardware before you can get it installed.
