Roto locks

[grovecreek]

The other day on a service call I located a leak on the suction side roto lock at the comp. Today I tryed a new seal but there is still a leak on the fitting that is mounted on the copper pipe. Are these brazed in or soldered? This is a Trane cond unit 7 year old one.

brazed ,i would replace the roto lock and make sure the compressor does not have a vibration

I've fixed e few leaking at the solder. You gotta use 45% with flux!!

Yes it is leaking at brazed joint. So no silfos just solder the joint in?

I use Safety-Silv 45. Flux coated silver brazing alloy rod
