Male/Female Unions provide secure, leak-proof connections for fuel, oil, and coolant lines in engines. Regular inspection for wear, corrosion, and proper sealing is essential to prevent leaks, pressure loss, or fluid contamination. Timely tightening or replacement ensures reliable performance and avoids engine damage due to fluid loss or air ingress.
