SOURCING SUPPORT NOTICE
FREE specification review for a comparable factory request
Eligible support is limited to up to 3%
Eligibility applies to qualified business buyers and is confirmed after we review your product, quantity, destination, and sourcing requirements.
An application fixes duty—oven door, electronics enclosure, food equipment after qualification—not a promised leak-free life. For silicone gasket material, the application usually locks medium, whether the part is a ring or a cut plate, and whether food-contact or flame files are even in scope. The service temperature in °F or °C that belongs on the request comes from the buyer’s process window, not from a catalogue reprint on this site.
What stays open after the use is described: Shore A, exact thickness, color, packing and the named ASTM or equivalent method. Those remain buyer decisions until a supplier confirms the quoted line.
Inner and outer diameter, or a drawing revision. Tensile strength (MPa / psi) and tear strength (kN/m) are acceptance questions only if the drawing names them.
| Ask | Unit |
|---|---|
| ID / OD | in or mm |
| Thickness | in or mm |
| Shore A | durometer the factory confirms |
Silicone versus FKM versus EPDM. Heat and oil change the purchase line. Compression set (%) belongs on the offer if it is a gate—not as a decorative range.
| Ask | Why |
|---|---|
| Compound | Medium and temperature differ |
| Cure system | Peroxide versus addition if the buyer named it |
| Color | Pigment can shift hardness claims |
This desk does not host STEP files. Describe the revision in the requirements box. After contact, drawings can be sent by the buyer’s own channel.
Send the open axesProcess engineers regularly face a trade-off between silicone rubber and fluoroelastomers (FKM / FFKM) for seals exposed to heat, oil and aggressive chemicals. The table is a purchase check, not a performance guarantee. The service temperature figure on this page is a question the buyer writes, not a rating this site reprints from a catalogue.
| Check | Stay on silicone gasket material | Move the brief toward FKM |
|---|---|---|
| Duty | Wide temperature, ozone, food-adjacent after qualification | Oils, fuels and many solvents where silicone swells |
| Axes named | Shore A, thickness, ID/OD or drawing | Same axes plus the hydrocarbon medium |
| Thermal gate | Buyer states °F or °C from the process, not from this site | Buyer states °F or °C; factory confirms the lot |
| Evidence | Named ASTM method; FDA 21 CFR 177 if claimed | Named ASTM method; plant ISO is still not a lot test |
| Cost conversation | Often the default for electronics and food-contact seals | Material cost is typically higher; this desk will not print a multiple |
We will not invent a service temperature in °F or °C or a leak-rate hour to complete the brief.
