Buying advice

When choosing a compression fitting tube insert, consider the tube material and size, operating pressure and temperature, and compatibility with your fitting brand. Brass inserts are versatile for general use, while stainless steel is best for corrosive environments. Check that the insert matches your tube's outer diameter exactly to ensure a leak-free seal. For pneumatic systems, budget-friendly Norgren inserts work well, while Parker Legris offers a broader range for hydraulic applications.
