Shop 2403-LH-SS Straight Large Hex Male JIC - Male JIC, Stainless Steel
SAE 070119 / MS 51519
Our Series 2403-LH-SS Large Hex Straight Male JIC x Male JIC hydraulic adapters, crafted from high-quality stainless steel, are designed to provide superior performance and durability in fluid power systems. These adapters feature a larger hex than the standard Series 2403, allowing for easier installation and increased torque when connecting two male JIC fittings. JIC (Joint Industry Council) fittings, defined by SAE J514, are known for their 37-degree flare seating surface and parallel threads, ensuring a secure, leak-free connection. The male JIC ends create a strong mechanical seal when the flared seats meet, enabling efficient fluid transfer. Ideal for high-pressure and demanding hydraulic applications, the Series 2403-LH-SS adapters are an excellent choice for professionals seeking a reliable, long-lasting solution.
