Width and cross-section on the quote
Every epdm rubber strip reply should state width and the profile letter or drawing. “Standard weather strip” is not a dimension.
Same-basis request
epdm rubber strip
An epdm rubber strip quotation only means the same thing as the next one when thickness, width and cross-section, Shore A and the document set sit on the priced line. Rubber Strips Sourcing issues that list to more than one factory. We are not a factory and we do not hold an appointment.
Check Compatibility
What sits inside the price
The extruded length, named packing and specified backing belong on the line. Adhesive lamination, a metal insert or a kit are billed separately unless written in.
Evidence, not a capability claim
Ask for the current dimensional page and the ASTM method for the quoted compound. A plant brochure is not that page.

How a supplier-proposed alternative for epdm rubber strip is evaluated
- Write the original axes next to the proposed axes.
- Ask which document covers the new compound or die.
- Keep the original line on file so later lots can be compared with the approved item.
Rubber Strips Sourcing does not convert a photo or a competitor part number into a “close enough” line without those axes.
Issue the same epdm rubber strip list to more than one plant
Quantity against each configuration, destination, sample versus production split, packing and Incoterms stay visible. Comparison is of total procurement cost, not a unit number alone.
