• Positive Drive: Features a pin or set-screw drive mechanism to handle the higher torque required to rotate the PTFE wedge against the shaft.
• Multi-Spring Option: Available in single or multi-spring configurations (T06) to provide uniform face loading, crucial for maintaining a seal with rigid PTFE components.
Key Features
• Chemical Duty: A robust PTFE wedge mechanical seal designed to replace the AES T0-series (T01, T03, T04). Ideal for aggressive chemicals where rubber O-rings fail.
• External vs Internal: Covers the full range of seat configurations: T01 (Standard), T03 (Seat with pin), and T04 (Clamped seat) to match various pump gland designs.
• Corrosion Resistance: The pure PTFE wedge provides near-universal resistance to acids, solvents, and alkalis.

Industry Solutions
Case Study
Solvent Pump: A paint factory's transfer pump seals were swelling due to Ketones. We replaced the elastomer seals with this T04 PTFE Wedge replacement. The PTFE wedge remained inert to the solvent, solving the leakage issue permanently.
Testimonials
The T04 replacement fitted our ANSI chemical pumps perfectly. The PTFE wedge is high quality and seats well on the shaft.
