Hydraulic Union Adaptor, 3/8"MJ X 3/8" MJ

Hydraulic Union Adaptor, 3/8"MJ X 3/8" MJ

The 2403X0606 Hydraulic Union Adapter is a straight hydraulic fitting designed to connect two 3/8" Male JIC (37° flare) connections, allowing hydraulic hoses or components with female JIC ends to be joined securely. Manufactured from durable carbon steel and rated for working pressures up to 5000 PSI, this union provides dependable strength for high-pressure hydraulic systems. The 37° JIC flare sealing surfaces create a reliable metal-to-metal seal, ensuring consistent performance in demanding agricultural, industrial, and mechanical applications. It’s a simple fitting that does an important job—keeping hydraulic lines connected so the fluid flows where it’s supposed to instead of exploring the shop floor.
