The Burgmann MG1 is EagleBurgmann's standard rubber-bellows single seal for plain shafts — water, HVAC and general industry. If the OEM won't sell you one piece, or the lead time is 8–16 weeks, we source a size-and-function equivalent through our coordination, delivered in 4–6 weeks.
Typical MG1 dimensions and duty. Your exact shaft size and elastomer drive the equivalent we source — confirm with the supplying factory.

The MG1 is a widely cross-referenced standard. Listed equivalents are matched by size and function; they are not OEM parts. We coordinate MG1-family equivalents from ISO 9001-certified partner plants through our coordination.
| OEM / brand | Equivalent model code |
|---|---|
| John Crane | Type 1 / Type 2 (standard bellows); MG13 ≈ Type 21 (compact) |
| Flowserve / Pac-Seal | Pac-Seal 190, 192 |
| AESSEAL | B02, B09U |
