Die Formed Rings
Universal Gaskets manufactures Preformed Graphite Ring Sets or as commonly known, Valve Packing Ring Sets.
Preformed Graphite Ring Packing Sets incorporate ultrahigh purity flexible graphite and ultrahigh purity graphite yarns to ensure low contaminant levels.

These packing sets provide maximum performance whether installed in a new valve or when repacking an installed valve.
A 45° scarf cut is available and preformed shape of each ring improves sealing compression and performance, without the need to cut or prepare each ring yourself.
These packing rings can be supplied as
