Frequently Asked Questions

What is a flareless male connector?

A flareless male connector uses a compression sleeve to seal the tube without requiring the tube end to be flared. This makes installation faster and reduces the risk of leaks.

Is this connector suitable for seawater systems?

While brass offers good corrosion resistance, it is not recommended for direct seawater contact due to dezincification risk. It is best used in closed-loop systems with fresh water, fuel, or hydraulic oil.

What tools are needed for installation?

Standard wrenches are sufficient for tightening the nut. Ensure the tube is cut square and deburred before assembly.

Can this connector be reused?

Flareless connectors are generally not recommended for reuse as the compression sleeve deforms during initial installation. For best results, use a new sleeve each time.
