Compatibility / Fitment Guide
Suitable for equipment designed for a 3L190 belt and a 3L pulley groove. Typical uses are compact fans, pumps, generators and light machinery; application names alone do not confirm fit.
Not interchangeable by length alone: A/4L and automotive 11A/13A profiles have different cross-sections. Verify pulley width, outside length and adjustment range.

Cross-reference numbers are for dimensional identification. Confirm pulley profile, belt route and tension adjustment before ordering.

No, not unless the equipment manufacturer explicitly approves it.
Is 19 inches the effective length?
The 3L190 designation uses nominal outside length.
What is supplied?
One V-belt.
