Learn what well service packing (WSP) is, how it works inside fracturing pumps, and how XHH Seals’ high-performance well packing enhances sealing performance under extreme hydraulic fracturing conditions.

S-Seals are spring-energized one-piece elastomeric seals, essentially a single-component anti-extrusion seal. It has an “S”-shaped rubber cross-section with a built-in coiled metal spring (garter spring) embedded in the elastomer. This integrated spring constantly pushes the sealing lip against the gland, boosting sealing force and preventing extrusion at high pressure. S-Seals replaces a traditional O-ring + backup-ring or 3-piece T-seal assembly with one part. Key benefits include...
