The Castair JIC 90-Degree Elbow Fitting (3/4" x 1/2"), part number JICE-90-3412, is a precision fitting for compressed air and pneumatic distribution systems. When a straight inline connection isn't possible — because of equipment placement, wall routing, or tight equipment bays — a 90-degree elbow is what keeps your air line running clean without kinking or restricting flow. This fitting handles the 3/4" JIC inlet to 1/2" JIC outlet configuration, which is common when stepping down from a main distribution run to a tool or branch line.
What This Fitting Does
JIC (Joint Industry Council) 37-degree flare fittings are a standard across shop air, hydraulic, and pneumatic systems. The 90-degree elbow design lets you change direction at the fitting rather than bending tubing — tube bends under pressure can collapse and restrict airflow or create stress points that fail over time. This fitting solves that problem cleanly with a machined elbow that maintains full flow path integrity at the connection point.
Key Features
- 90-Degree Elbow Configuration: Directs line flow at a right angle without stressing or bending tubing
- 3/4" x 1/2" Sizing: 3/4" JIC inlet steps down to 1/2" JIC outlet — ideal for branch-off from larger mains
- JIC 37-Degree Flare Standard: Compatible with standard JIC fittings used across pneumatic and hydraulic installations
- Cast Air Manufactured: Sourced from Cast Air's compressed air product line, built to the same quality standards as their compressor and piping components

Typical Applications
- Compressed air distribution routing in auto repair shops and industrial facilities
- Direction changes in pneumatic tool feed lines where space is limited
- Connecting air lines to equipment where a straight fitting won't clear adjacent components
- Reducing from a 3/4" main distribution run to a 1/2" branch or tool drop
