## ⚙️ Key Features

-   For the TAD720VE compressor unloading or control mechanism
-   Listed for 3 applications on TAD series engines
-   The lighter 0.048 kg gasket 20476069 seals the main compressor joint

## 🔌 Function

Seals the compressor control or unloading cylinder joint, keeping control air to its own passage so the compressor loads and unloads properly.

## ⚠️ Common Signs of Failure

-   Compressor running continuously or failing to unload
-   Air escaping audibly at the control cylinder
-   Slow air pressure build-up and frequent cycling
-   Gasket found blown through or hardened on strip-down
-   Control cylinder face found scored or corroded

## 🛠️ Service Notes

-   Check the control cylinder and its bore for scoring before condemning the gasket - a scored bore will leak with a new gasket fitted
-   The main compressor joint takes the 0.048 kg gasket 20476069, so confirm which face you are sealing
