Key Features
• Chemical Duty: A robust PTFE wedge AES mechanical seal (T01/T03/T04) designed for aggressive acids, solvents, and alkalis where NBR/EPDM/Viton O-rings would swell or degrade—ideal for chemical process pumps.
• Full T-Series Coverage: Covers T01 (standard seat), T03 (seat with anti-rotation pin), and T04 (clamped seat) configurations to match your existing pump gland design. Also available in multi-spring T06 for uniform face loading.
• Positive Drive System: Features pin or setscrew drive mechanism to rotate the rigid PTFE wedge against the shaft, preventing slippage under high starting torque—a key advantage of this AES mechanical seal replacement over plain friction-fit designs.
• Near-Universal Corrosion Resistance: The pure PTFE wedge provides exceptional resistance to a wide pH range and most organic solvents, making the AES T01 T03 T04 T06 mechanical seal replacement suitable for multipurpose chemical plants.
• John Crane Type 9 Compatible: Dimensionally interchangeable with John Crane Type 9 series, allowing consolidation of spare inventory across AES and JC equipped pumps.

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.

FAQs about AES T01 T03 T04 T06 Mechanical Seal Replacement
Q: Is this equivalent to John Crane Type 9?
A: Yes, the AES T0 series is mechanically equivalent to the John Crane Type 9 series. Our replacement is dimensionally compatible with both, offering a versatile solution for chemical pumps.
Q: Is this AES T-series replacement dimensionally identical to the original AESSEAL T01/T03/T04 seals?
A: Yes. Our AES mechanical seal replacements are reverse-engineered to OEM envelope dimensions—shaft fit, seat O.D., and overall length match the original AESSEAL® T-series. Direct drop-in, no pump modification required.
Q: What is the advantage of a PTFE wedge seal over a standard O-ring pusher seal?
A: The PTFE wedge resists virtually all chemicals except molten alkali metals and fluorine. It will not swell, harden, or extrude in aggressive media—making it the preferred AES mechanical seal type for acid and solvent services.
Q: Can I use this T04 replacement in place of a John Crane Type 9?
A: Yes. The AES T0-series is mechanically equivalent to John Crane Type 9. Our replacement fits both, offering a versatile solution for mixed-fleet plants.
