The Series 6565-SS Straight Stainless Steel Female JIC Swivel x Female JIC Swivel adapters are high-quality hydraulic fittings designed for fluid power systems. These adapters feature two female JIC (Joint Industry Council) 37° flare connections made from durable stainless steel, providing reliable, corrosion-resistant performance in demanding environments. JIC fittings create a secure mechanical seal by allowing the male flared and female coned seats to make contact, ensuring a leak-free connection. These fittings are widely used due to their versatility in size, shape, and material options, as well as their ability to be disconnected and reconnected repeatedly without deformation. The absence of O-rings makes them ideal for high-temperature applications, but they are limited to non-critical, hydraulic fluid systems and may suffer from flare damage if over-tightened.
