TinnerFlow™2nd YearGREEN · Standard CorrectionAdjustable Gored Elbows
Adjustable gores should rotate smoothly. If the seams are crimped, loosen and reset the gores before locking the angle, or replace the damaged fitting if it cannot hold shape.
Gored adjustable elbows are meant to rotate on their seams until the angle is set. If the seams get crushed or overworked, the fitting can freeze, ovalize, or shrink the internal opening.
Back off the force, work the gores loose carefully, reset the fitting to the required angle, and lock it only after the throat stays round and open. If the metal is kinked badly, replace the elbow instead of burying the restriction.
Do not crush adjustable gore seams so tight that the elbow loses diameter or freezes out of shape.
A distorted elbow restricts airflow, leaks at the seams, and makes the downstream run harder to align.
