Flare vs Bell
The nomenclature of bells and flares varies throughout the industry. We follow a simple definition. 1) A flare is a sloping expansion of a tube. They assist
in guiding an object or carrier into the pneumatic tube system. Flares are usually defined by the ID, angle, and lengths. FLARE
A bell is a coupling, an expansion of a tube to couple without a sleeve. The ID of a tube is expanded to its OD. The expansion is not sloping (as in a
flare) but is parallel. Standard flares have a 2-3" transition
and 3" parallel section.
BELL: Bells are usually defined by their ID's and transition length.
We have several blogs on how to couple bells. Flares are not coupled; they are placed at the beginning and/or end of a pneumatic line.
We can flare or bell all of our transparent tubing products to your needs.
