Buyer-focused guides for material selection, profile measurement, manufacturing quality, installation and OEM sourcing. Technical references are identified where applicable, while project-specific limits remain subject to drawing and application review.
Begin with the sealing function and mating geometry, then select the material, cross-section, manufacturing route and validation method. These guides separate general engineering considerations from limits that must be confirmed for a specific drawing and application.
Use the comparison guides for early selection and the measurement, manufacturing and installation guides when preparing an RFQ or approval plan.
| Product family | Best starting page |
|---|---|
| Custom rubber extrusions | Rubber extrusion profile guide |
| EPDM sealing strips | Solid, sponge, bulb and channel profile overview |
| Automotive weatherstrips | Automotive manufacturing guide |
| Self-adhesive foam seals | Foam profile selection |
| PVC and rubber edge trims | Edge trim profiles |
| Brush seals and wool pile | Brush seal mounting and pile selection |
Use the path that matches your current purchasing or engineering decision.
Start with service temperature, weather, fluids and compound-specific limits.
2 · GeometryPrepare the cross-section, mating dimensions, tolerances and RFQ package.
3 · ProductionReview tooling, trials, sample approval, extrusion, inspection and packing.
4 · QualityDefine control stages, acceptance references, records and change control.
Each path moves from an engineering question to the product or manufacturing page needed for an RFQ.
| Current task | Read first | Then review | Product handoff |
|---|---|---|---|
| Replace an unknown profile | Measure the cross-section | Compare material requirements | Custom extrusion development |
| Select adhesive foam weatherstrip | Compare D, P, E and I shapes | Compare EPDM and PU foam | Foam seal category |
| Specify edge trim | Calculate grip range | Plan cutting and installation | PVC edge trim category |
| Specify brush or pile seal | Choose pile height | Review installation controls | Brush seal category |
| Prepare a production release | Understand process stages | Define inspection and change control | Custom manufacturing service |
