Sil-Fos-15 Solder Brazing Rings 7/8" Lucas Milhaupt Part# 98705 (Qty 25)

These are awesome when brazing something in a difficult location, and/or when the solder has to flow upwards, and/or there's not a great fit and one wants to ensure a good deep joint. Saves a ton of time when dealing with difficult cases.

Exactly what I needed.
