UNION - HYDRAULIC - FLARE (CAT CT307984)

A damaged hydraulic flare union can cause fluid leaks that reduce system pressure and lead to erratic operation. This aftermarket replacement part references CAT as the OE maker and cross-references part number CT307984. The union connects two hydraulic lines using a flared end to create a metal-on-metal seal. A loose or worn union may allow contamination to enter the circuit, accelerating component wear. During a pressure test, a leaking union often produces visible drips or a steady stream of fluid. The item ships at approximately 0.07 POUNDS. Verify the serial number or application, then call (562) 693-7748.
