The main series classified by connection structure
1. 1J — JIC Male 74° Cone
The 1J series is a straight JIC male fitting with a 74° cone sealing surface. It is designed to connect hydraulic hoses or tubes to female JIC ports and fittings.
The 1J fitting is widely used because of its simple structure, reliable sealing performance, and suitability for high-pressure hydraulic applications.
| 模型 | 标准 | 核心结构 | Connection | 典型应用 |
|---|---|---|---|---|
| 1J | SAE J514 / JIC | Straight fitting with 74° cone | JIC male 74° cone | Hydraulic hoses, tubes, valves, pumps and manifolds |
| 1J | SAE J514 | Steel body with precision-machined cone | Male JIC to female JIC | Construction machinery and industrial hydraulic systems |
| 1J | JIC 74° | One-piece or assembled fitting structure | Straight connection | High-pressure hydraulic lines and equipment |
| 1J | SAE J514 | Precision-machined sealing surface | 74° flare connection | Mobile hydraulic equipment and hydraulic power units |
The 1J9 series is a 90° elbow JIC male 74° cone fitting. Compared with the straight 1J, the 1J9 changes the connection direction by 90°, making it especially useful where installation space is limited or the hydraulic hose needs to change direction.
Its JIC 74° cone provides the same basic sealing principle as the 1J series, while the elbow configuration offers greater flexibility for hydraulic hose routing.
