Alfagomma VS4 Ferrules are high-quality, two-piece inserts designed specifically for Flexor Rig and Alfabiotech 2000 hoses with 2 ½" and 3" inside diameters (ID). A ferrule is a fitting used to securely compress the hose onto the fitting, creating a strong, leak-proof seal. The VS4 Ferrules are designed to ensure a durable and reliable connection in demanding fluid systems, particularly in high-pressure environments. For optimal performance, these ferrules require a VS4 skive ferrule, meaning the hose must be prepped by removing a small portion of its outer layer before installation to ensure the ferrule can securely grip the hose. This two-piece design is ideal for industrial applications where secure, long-lasting hose connections are essential.
