Product Introduction

Used in plumbing, HVAC systems, and industrial piping applications to change the direction of the flow by 90 degrees

Size: Ensure that the elbow's inner diameter matches the tube or pipe it will connect to, and its outer diameter aligns with the flanges or other fittings in your system.

Surface finish: Some applications require a high level of cleanliness, so choose fittings with appropriate surface finishes to minimize particle generation.

Thread type: Match the thread type of the elbow to the rest of your system to maintain integrity and prevent leaks.
