1. Gather what the buyer already has
Drawing or ID/OD, compound family, Shore A if known, medium, temperature in °F or °C, quantity and destination. A photo or competitor number is a starting point, not a specification.
rubber gasket material on one comparable request
Rubber Gasket Sourcing turns rubber gasket material into a brief several factories can answer on the same axes. We do not sell a compound from stock and we do not rate factories as premium or cheap on our own authority.
How the same-basis request is built
2. Ask each factory the same Shore A question
Each supplier must confirm Shore A hardness on the quoted rubber gasket material. If they answer with a brochure range, ask which value is on the priced line.
3. Handle an equivalent offer in writing
If the exact compound is unavailable, the substitution must name what changed: thickness, ID/OD, Shore A, temperature, density in g/cc, or the ASTM method. An unnamed “equivalent” is a new request.
4. Compare total procurement cost
Line up packing, Incoterms, documents and the sample / production split next to the money figure. We do not recast a cheaper Incoterm as a percentage saving.

| Question | Why it changes the quote |
|---|---|
| Shore A on the priced line | A 70A NBR cut and a 50A NBR cut are different goods even at the same ID/OD |
| ASTM D2000 or equivalent method | The report must cite the method and condition, not only the plant name |
| Compression set (%) | Needs ASTM D395 time and temperature if claimed |
| Tensile strength (MPa / psi) | Only useful when the file names the test method and the grade |
| Origin of melt or finishing | The receiving plant may ask; a trading-company address is not that field |
