Commercial cooler door gaskets are made in different dart and bulb styles. Ordering by size alone is not enough—you must match the retainer profile that snaps into your door channel.
Common gasket styles
- Magnetic snap-in: Dart presses into a channel; magnetic bulb seals to the steel frame.
- Screw-on magnetic: Fastened with screws; common on older or specialty doors.
- Compression / non-magnetic: Used where magnetic pull is not required.
How to choose
- Photograph a cut cross-section of the old dart.
- Measure outside dimensions.
- Browse gaskets by style/profile or shop by brand.
