304C04 (often formatted as 304-C-04 or 0304-C-04) is the standard industry part number for a #04 Female JIC (SAE 37° Flare) Hydraulic Cap Nut.
It is engineered to plug, protect, and seal open male JIC hydraulic lines or port adapters from high-pressure fluid leaks and environmental debris. The alphanumeric designation breaks down into the following technical specifications:
Model & Spec Breakdown
- 304-C / 0304-C (Series): Identifies the component as a Female JIC Cap. It features internal straight threads and a 37-degree cone seat that compresses against a matching male flare to create a tight mechanical seal.
- 04 (Size): Indicates the hydraulic dash size in 16ths of an inch (
4/16″):- Tube Outer Diameter (O.D.): 1/4-inch.
- Thread Size: 7/16-20 UNF straight threads.
- Hex Nut Size: Typically requires a 9/16-inch (
0.562″) wrench to tighten.
Key Performance Features
- High-Pressure Capability: Built to withstand intense workloads within heavy fluid systems, typically supporting dynamic working pressures up to 7,500 PSI.
- Standard Compliance: Fully compliant with SAE J514 engineering guidelines, ensuring exact fitment and thread alignment across standard industrial and commercial machinery.
- Interchangeability: Directly cross-references with equivalent part numbers across major fluid-power brands, including the Brennan 0304-C-04, Parker 4 FNTX-S, Gates 04FJ-CAP, Aeroquip 210292-4S, and Weatherhead C5129X4
