Probably so I usually add a swivel tee to the discharge access and put it on there. No headache and a lot simpler.

From my experience new Trane units do not have schraders under the HPS. From the thread jimj linked I was told that there is a new standard as of 2005 that states there can be no valves of any sort between the compressor or condenser (not sure which one) and the HPS. I would either put in a tee like smj recommends or braze on a saddle tap.

No cust is going to pay me to recover a unit to change out a hps. So, I will install a swivel on a high side port, mount a new sw on one and use the other for an access. Wire it, test it, done.

I am yet to see any proof of this.
I treat every pressure switch as if it doesn't have a core behind it. Loosen it and give it the wiggle test as you slowly unscrew it, if it doesn't stop leaking by the time you get down to the last two threads you know you are screwed.UA LU189
