Refrigerated Truck Door Seal Manufacturer
Direct Answer

OEM Sealing Profiles Built Around Your Application

Onaseal supports B2B buyers, distributors and equipment manufacturers with drawing-based or sample-based profile development. The correct solution is selected from the mating geometry, operating gap, installation method, material exposure and order requirements—not from appearance alone.

For a dependable quotation, provide the cross-section, critical dimensions, material preference, color, required length, annual quantity and application photos. Trial samples should be fitted to the real assembly before mass production.

Door-System Measurement

How to Specify a Refrigerated Truck Door Seal

InputWhat to measure or defineWhy it matters
Retainer or mounting channelOpening width, internal width/depth, lip shape and insertion directionControls how the profile mounts and remains retained
Closed-door gapMinimum and maximum gap on all four sides and near hinges/latchesDefines the required lip or bulb contact range
Compression directionFace compression, side wipe or combined movement during closingDetermines section orientation and lip geometry
Corner constructionContinuous bend, cut joint, welded/moulded corner or separate piecesAffects contact continuity and installation length
Door hardware and alignmentHinge/latch condition, panel flatness and local gap variationA seal cannot compensate reliably for every alignment defect
Cold-chain environmentContinuous and peak temperatures, icing, washdown, UV and cleaning agentsGuides compound and validation requirements
Manufacturing Capability

What Onaseal Can Customize

Cross-Section Development

Review from CAD drawings, dimensions, samples and mating-part geometry.

Material & Compound

Material selection based on compression, weather, abrasion and service environment.

Secondary Processing

Cold-Chain Validation

Sample Approval Checks for Refrigerated Door Seals

CheckAcceptance questionTest condition
Mounting fitDoes the foot insert and remain retained without profile damage?Actual retainer/channel across dimensional variation
Contact continuityDo lips or bulbs contact around sides, header, sill and corners?Closed door at minimum and maximum measured gaps
Closing effortCan hinges and latches close without excessive force or seal roll-over?Complete door assembly at ambient and specified cold condition
Low-temperature flexibilityDoes the selected compound retain required flexibility and recovery?Buyer-defined minimum service temperature after conditioning
Leak managementDoes the assembly meet the buyer's air, water or thermal-leak criterion?Complete door-system test; profile inspection alone is insufficient
Service durabilityAre icing, washdown, UV, cleaning and repeated door cycles acceptable?Declared duty cycle and environmental validation plan

Before approving a sample, use the sealing strip installation guide to plan retainer cleaning, measurement, cutting, corner fitting and final contact inspection on the actual refrigerated-door assembly.

Temperature context: Trelleborg's Material Selection Guide lists a typical EPDM sealing-profile range of −40 to +120 °C. This is comparative material guidance, not a guaranteed limit for every EPDM compound or finished door seal. The specified compound and complete refrigerated-door assembly must be validated at the project's actual minimum temperature.

Four-Step OEM Cooperation

  1. Send a drawing, sample, photos and application requirements.
  2. Confirm section, material, dimensions, tolerances and commercial quantity.
  3. Approve tooling and trial samples after fit and performance checks.
  4. Proceed with batch production, inspection, packaging and export delivery.

  • Continuous/peak temperature, icing and washdown exposure
  • Door dimensions, cut/set lengths, quantity and packaging
FAQ

Buyer Questions

Yes. Send a perpendicular cross-section photo, dimensions, retainer details and an uncompressed sample if available.

Channel or retainer width, overall profile width/height, lip length and the closed-door gap are essential.

Sample fitting is recommended before bulk production, especially for existing door systems.
