Alfagomma AS4 Ferrules are high-quality, two-piece inserts designed to securely connect a wide range of hoses, including wire and textile braided hoses, thermoplastic hoses, Flexor 4, PTFE hoses, and Alfabiotech hoses. They accommodate hose sizes from ³⁄₁₆" to 2" in diameter, including Alfabiotech 3000 (1 ¼" and 1 ½") and Alfabiotech 4000 (³⁄₈" to 1 ¼"), as well as smaller ID spiral wire reinforced hoses. A ferrule is a metal or plastic fitting used to compress the hose onto the fitting, creating a tight, leak-proof seal. The Alfagomma AS4 Ferrule ensures a reliable, durable connection by securely locking the hose in place, making it ideal for high-pressure fluid systems and demanding industrial applications. With a two-piece design, it offers easy installation while providing long-lasting, secure hose connections in fluid power systems.
