TH350 Teflon Pump Ring Kit, 5 Piece - (3) Large, (2) Small

The ATI Racing Teflon Ring is a durable, precision-molded seal for ATI's Pump assemblies. Engineered to create a tight, leak-resistant barrier, this ring prevents fluid bypass at elevated pressures and helps maintain converter charge and system hydraulic integrity. Manufactured to high-performance standards, the ring ensures consistent oil routing and lubrication during launching and high RPM operation. Its low-friction Teflon composition provides long service life in demanding applications, safeguarding cooler flow and clutch pressure in both racing and street-driven builds.
