SMC DOT Straight Cartridge

The SMC DOT Straight Cartridge is a push-to-connect (PTC) replacement unit designed to restore proper sealing in your air suspension manifold. If you’re experiencing leaks at the PTC ports on your Air Lift or AccuAir manifold—and your air line is cut clean at a perfect 90° angle—the internal O-ring is likely worn or damaged and may need replacement.

This cartridge allows you to replace the internal sealing component without needing to replace the entire manifold, helping get your system back to proper working condition.

Key Features:

• Direct replacement PTC cartridge for manifolds
• Restores sealing performance in leaking ports
• Compatible with Air Lift and AccuAir manifolds
• Push-to-connect design for straightforward installation
• DOT-rated component

Important Notes:

• Replacement should be performed with caution
• We strongly recommend professional installation
• Any replacement will void your manifold warranty

A cost-effective solution for fixing leaks—when done properly.
