A compression elbow (or elbow compression) is a type of hose fitting that provides a facility to connect hoses and tubes in various configurations such as in-line, offset and multi-port connections. Compression elbows are available in various configurations such as 30°, 45°, 60° or 90°. Compression elbow manufacturers use various metals and plastics. Compression elbows are very useful in specialty fluid systems that transport gases, refrigerants, compressed air and hydraulic fluids.

A compression elbow is an essential component in various industries such as HVAC (heating, ventilation and air-conditioning), chemicals, oil and gas, paper and pulp, medical and pharmaceuticals.

Some important parameters you must consider before purchasing a compression elbow are:

1. Operating system pressure
2. Maximum pressure that the compression elbow can withstand
3. Dimensions of the compression elbow: angle, inside diameter, outside diameter and length of compression elbow sleeve
4. Required quantity of the compression elbows in an industrial setup
