A pinpoint leak on a discontinued sight glass on a vehicle's liquid line is hard to seal because repair shops are reluctant to modify the part and junkyard alternatives require excessive time to find.

Existing solutions either require a shop willing to modify a discontinued part (which they refuse) or spending significant time hunting for a compatibly angled fitting in junkyards, with no quick, reliable repair method that won't risk system contamination.
