57 mm Refrigerated Truck Door Seal
Wide refrigerated truck door seal with a 57 mm overall width, 50 mm inner channel and flexible lips up to 50 mm high.
Confirm the 50 mm Mounting Channel
The 57 mm overall width identifies this wide profile family, but the 50 mm inner channel and retainer geometry determine mounting compatibility. The two lip heights must also reach the intended contact surfaces without excessive folding or closing force.
Measure an uncompressed end section and the closed-door gap at the top, sides and bottom. Include photos showing the retainer and the direction each lip contacts the frame.
Reference Dimensions and Buyer Checks
| Reference | Buyer check |
|---|---|
| 57 mm overall width | Confirm available mounting space and external section clearance |
| 50 mm inner channel | Compare retainer width, depth and locking geometry |
| 36 mm / 50 mm lips | Verify lip orientation, free reach and contact surfaces |
| Installed door gap | Record minimum and maximum clearance around the perimeter |
| Joint arrangement | Confirm corners, joining method, cut length and packing format |
Cold-Chain Door Sealing Profile
This wide U-channel refrigerated truck seal is designed for insulated vehicle doors requiring a 50 mm inner mounting width. The asymmetric flexible lips use 36 mm and 50 mm reference heights. Compatibility depends on the actual retainer, available mounting space, lip direction and installed door gap.
Typical Applications
- Large refrigerated truck doors
- Cold-chain transport vehicles
- Insulated cargo body doors
- Wide-channel replacement seals

What “57 mm” Does—and Does Not—Confirm
The 57 mm name is an overall-width reference for this profile family. It is not a tolerance, a working gap or proof that the seal fits a particular truck door.
| Dimension | Purpose | Approval requirement |
|---|---|---|
| 57 mm overall width | Checks the external section envelope and available space | Measure the relaxed profile at the agreed reference points |
| 50 mm inner channel | Checks compatibility with the mounting retainer | Compare channel depth, opening and locking geometry—not width alone |
| 36 mm and 50 mm lips | Provides two free-reach references | Confirm contact direction, deflection and closing force on the door |
| Door-to-frame gap | Defines the installed sealing requirement | Record minimum and maximum values at the header, sill, hinges and latches |
Materials, Profile Sizes and Door Applications
Use these images to compare material construction, representative mounting-channel sizes, three-sided and four-sided gasket layouts, installed door details and typical transport or storage applications. Confirm the exact cross-section, retainer and closed-door gap before ordering.
Designed for Refrigerated Transport
Defined Dimensions
Dimension reference: 57 mm overall width and 50 mm inner channel.
Asymmetric Lips
36 mm and 50 mm flexible lips support different sealing contact points.
Wide Mounting Channel
Suitable for compatible wide retainers and insulated door frames.
Sample Verification
Final fit should be confirmed against the actual mounting channel or sample.
Checks Before Releasing a 57 mm Seal Order
| Check | Pass condition |
|---|---|
| Retainer fit | The channel seats fully and remains retained without tearing or excessive installation force. |
| Lip contact | Both lips contact their intended surfaces around the full door perimeter. |
| Closing effort | The door latches without unacceptable force, lip roll-over or local binding. |
| Cold condition | The selected compound keeps the required flexibility and recovery at the specified temperature. |
| Corners and joints | Contact remains continuous at bends, cut joints or formed corners. |
Approve the profile on the actual door assembly. A short straight sample alone cannot verify corners, alignment or the complete closing cycle.

Frequently Asked Questions
The image dimensions are reference values. Final tolerances are confirmed after material, sample and application review.
Yes. Custom tooling may be developed when the required cross-section differs from the standard profile.
Provide channel measurements and an original sample; a trial sample can then be checked on the actual door.
