Is there a word or phrase that combines the meanings of 'inlet' and 'outlet'?

I wanted to tell a friend that I've discovered a new social outlet, but then I realized it was also an inlet. I was wondering if there's a word or phrase that combines those two meanings.

Something like pipeline perhaps? But social pipeline doesn't sound right.

Perhaps channel. The term has multiple meanings, several of which align with your concept. For example, Merriam-Webster offers, among others

• a means of communication or expression: as (1) : a path along which information (as data or music) in the form of an electrical signal passes (2) plural : a fixed or official course of communication: went through established military channels with his grievances
• a way, course, or direction of thought or action: new channels of exploration

The phrase social channel might work.
