What ultimately provides the seal?
I'm talking about the common 1/4" service ports we connect our guages to. A member of another forum (Non HVAC&R related) called me out on what I believe to be true.
So what's y'alls thoughts?
When it comes to providing the actual sealing and containment of refrigerant within a given circuit at the schrader type service port, is it the valve core or the cap (that I keep finding laying on the floor of the compressor section )?
I say it's the cap.
While we're at it, if you believe it's the cap, what type do you prefer (and why)? Metal for its new metal-to-metal seal with each snugging or the metal/plastic with an O-ring?
I'm a new member of these forums and just cut the cheese in the back of the room. Opps.
