The 304CX06 Hydraulic Adapter (3/8" JIC Cap) is a solid hydraulic cap designed to seal and protect unused JIC hydraulic fittings in fluid power systems. Built as a one-piece carbon steel fitting, it features a 37° JIC flare connection that mates securely with standard JIC fittings to create a dependable, leak-resistant seal. This cap is commonly used to block off hydraulic lines during maintenance, transport, or system assembly, helping prevent contamination and fluid loss. In other words, it’s a small but essential piece that keeps dirt out and hydraulic oil exactly where it belongs.
