Elbows – Flanged

Standard radius (1.5) and long radius (2.5) flanged elbows are available in 30 to 90-degree elbows; from 24 to 48 in diameter; and 16 and 18 gauge stainless or galvanized steel.

Elbows -Flanged, Pleated / Non-Welded

The non-welded, unidirectional, pleated and flanged elbow is very cost efficient in systems where a small amount of leakage is acceptable (the wood industry). Available in galvanized steel only.
