T-seals combine elastomer core with anti-extrusion backups for high-pressure rod and piston sealing in mud motors. The T-shape minimizes twist during reciprocation. HNBR T-seals endure 500 RPM and 5,000 PSI in drilling. PEEK backups bridge extrusion gaps at 200°C. Low friction extends bearing life. In polycrystalline diamond compact bits, they prevent washout.
