Castair CE3434 Compression Elbow -- 3/4-inch x 3/4-inch
The Castair CE3434 is a 3/4-inch x 3/4-inch compression elbow for air compressor discharge tube assemblies. It handles 90-degree direction changes in the copper discharge tube run on larger Castair compressors -- commercial series, industrial series, and any unit where the discharge connection uses 3/4-inch copper tubing (CT75). No soldering or flare tools are required for installation or service.
The 3/4-inch discharge tube hardware -- including the CE3434 elbow and the CA3434 straight adaptor -- is used on higher-output compressors where the larger tube bore handles greater CFM discharge volume. If you are rebuilding the discharge tube assembly on a Castair commercial or industrial series unit with a 3/4-inch outlet, the CE3434 is the 90-degree fitting for routing direction changes.

- CE1212: Compression elbow 1/2-inch x 1/2-inch -- 90-degree, smaller compressors
- CA3434: Compression adaptor 3/4-inch x 3/4-inch -- straight, larger compressors
- CE3434: Compression elbow 3/4-inch x 3/4-inch -- 90-degree, larger compressors (this part)
- DT34: 3/4-inch discharge tube with fittings -- complete assembly
- CNS34: 3/4-inch compression nut and sleeve -- replacement hardware
Installation Notes
Cut tube ends square and deburr before inserting into the compression fitting. Inspect the tube end and compression nut for damage when replacing a failed elbow -- reusing damaged ferrules or nuts will result in leaks. Check for leaks after installation before running under load.
