A high-quality 3/8″ brass compression fitting adapter from YSIL, designed for seamless connections between 3/8″ OD tubing and 3/8″ hose barbs. Crafted from premium brass, this fitting delivers exceptional rust and corrosion resistance, ensuring long-term reliability in demanding applications—ideal for automotive fuel systems, hydraulic lines, or general fluid transfer setups.
The YSIL adapter features a universal replacement design, allowing you to swap out only the fitting (not the entire assembly) for cost-effective repairs. Its robust construction includes a sleeve and ferrule assembly to prevent leaks, while the hose barb end can be secured with a clamp for added sealing integrity. Installation is straightforward: Use a wrench to tighten the ferrule during assembly, ensuring a secure, leak-proof connection.
