The Castair JICA3412 is a reducing JIC adapter fitting that steps down from a JIC-34 (typically 1-1/16-inch JIC 37-degree flare) connection to a JIC-12 (3/4-inch JIC 37-degree flare) connection. In Cast Air's air distribution system, this reducer is used where a main trunk line drops to a smaller branch line — moving from a higher-flow trunk to a lower-demand drop point without changing fitting standards.
Key Details
- Part Number: JICA3412
- Configuration: JIC adapter, 34 x 12 — steps down from JIC-34 to JIC-12
- Thread Standard: JIC 37-degree flare, both ends
- Application: Reducing from a large-diameter trunk run to a smaller branch or drop point in a Cast Air JIC distribution system
- Flow Note: Reducing the line size at the adapter will increase velocity and decrease volume at the outlet — size appropriately for downstream tool demand
