Dry-break connectors are essential components used in hydraulic systems to facilitate quick and clean connections and disconnections of hydraulic lines. These connectors are designed to prevent fluid loss and the introduction of air the hydraulic side of your dampers. Additionally, dry-break connectors are critical for installation for many vehicle applications. This guide will provide step-by-step instructions on how to use dry-break connectors safely and efficiently.

Safety Precautions

Before proceeding with the connection or disconnection of hydraulic lines using dry-break connectors, it is crucial to ensure safety by following these precautions:

  1. Fully Extend Dampers: ensure the dampers are fully extended/open.
  2. Relieve Gas Pressure: Always relieve the gas pressure in your remote reservoirs before attempting to connect or disconnect any lines. This step is vital to prevent accidents and ensure the safe handling and longevity of the connectors.
  3. Wear Protective Gear: Use appropriate personal protective equipment (PPE) such as gloves, safety glasses, and protective clothing to protect against accidental fluid discharge.
  4. Inspect Equipment: Check the dry-break connectors and hydraulic lines for any signs of wear, damage, or contamination. Replace any defective components before use.

Tools and Materials Needed

  • MCS damper system optioned with dry-break connectors
  • Clean microfiber cloth
  • PPE (gloves, safety glasses, protective clothing)

Step-by-Step Instructions

Disconnecting Dry-Break Connectors

  1. Depressurize the remote reservoir: Locate the schrader valve assembly on the gas side of the remote reservoir. Remove the schrader valve cap and depress the schrader valve stem to release the gas pressure.
  2. Verify Pressure Release: Confirm that the system pressure has been fully relieved by checking with a pressure gauge or you no longer hear gas releasing.
  3. Grab the fittings: The female side of the connector assembly has a knurled sleeve. Pull back on this sleeve while securely holding the male side of the connector assembly. Pull the connectors away from one-another.

Connecting Dry-Break Connectors

  1. Clean the Connectors: Use a clean cloth to wipe down the male and female ends of the dry-break connectors. Ensure they are free from dirt and debris.
  2. Align the Connectors: Position the male and female connectors so that their coupling mechanisms align properly.
  3. Engage the Connectors: Push the male connector into the female connector until you hear or feel a click, indicating a secure connection.
  4. Check the Connection: Gently pull on the connectors to ensure they are securely connected and will not disconnect under pressure.
  5. Pressurize the Remote Reservoirs: With your shock gauge tool, fill the reservoir with nitrogen gas. See the article below for choosing gas pressure values.

Troubleshooting Tips

  • Leakage During Connection: Ensure that both connectors are clean and undamaged. Check that the connectors are fully engaged and locked in place.
  • Difficulty in Connecting: Zero the adjuster settings on the shaft in the damper body and on the adjuster(s) at the canister assembly.
