FAQ
Burgmann-Compatible Seal FAQ
Are these genuine Burgmann seals?
No — they are OEM-compatible equivalents built to Burgmann and EagleBurgmann dimensions. They are not sold as genuine Burgmann parts.
My Burgmann seal is not on this page. Can you make it?
Most likely. The models here are examples. Send the seal part number, a drawing or the old seal and we confirm the fit before quoting.
Can you work from the pump model?
Not on its own. We build from the seal itself: its part number, its drawing or a sample of the old seal.
Can you match obsolete Burgmann seals?
Yes — we machine discontinued patterns from a sample or drawing.
