VSG ProPack Rings
VSG ProPack Rings are precision-engineered pure graphite center rings
produced using the same proprietary technology as VSG ProPack packing sets.
By eliminating die-formed tooling, custom-fit rings can be manufactured in as
little as 48 hours. Designed for valve stem applications that do not require end
rings, they can be used alone or combined with braided packing materials
to provide reliable sealing and fast turnaround for maintenance needs.
