Description
2408X14 (commonly formatted as 2408-14) is the standard industry part number for a #14 Male JIC (SAE 37° Flare) Hex Head Hydraulic Plug.
It is engineered to thread directly into a matching female JIC opening to cap off and seal an open fluid line or port securely. The alphanumeric designation breaks down into these technical specifications:
Model & Spec Breakdown
- 2408 / 2408X (Series): Identifies the component as a Male JIC Flare Tube Plug. “2408 seals an open female JIC 37° flare port as a plug, presenting a male 37° flare nose that seats directly against the port cone.” -- [Higher Fittings]. It relies entirely on this metal-to-metal contact to form a seal without needing thread tape or liquid sealant.
- 14 (Size): Indicates the hydraulic fraction size in 16ths of an inch (
14/16″):- Tube Outer Diameter (O.D.): 7/8-inch.
- Thread Size: 1-3/16-12 UN/UNF straight threads.
- Hex Nut Size: Measures 1.250 inches (requires a 1-1/4″ wrench to tighten).
Key Performance Features
- High-Pressure Capability: Built from high-strength carbon steel or stainless steel to support modern heavy-duty machinery, typically rated for dynamic working pressures up to 5,000 PSI with a 4:1 safety burst ratio
- Standard Compliance: Fully compliant with SAE J514 (specifically code 070109) design frameworks. This ensures reliable thread tolerances, dimensions, and absolute cross-compatibility with global hydraulic systems.
- Universal Interchangeability: Directly substitutes for equivalent part numbers across major fluid-power brands, including Parker 14 PNTX-S, Aeroquip 900599-14S, Weatherhead 5229X14, and Gates 14MJ-Plug.
