rubber cord seal
Turn a rubber cord seal search into one written request several factories can quote on the same basis. Rubber Cord Sourcing does not own an extrusion die, a splice shop or a published discount schedule. Diameter or a standard size reference, Shore A, packing and documents stay visible instead of being filled from a catalogue default.
Two unit prices mean the same thing only when every quotation states inner and outer diameter — or the standard size reference used to cut the seal — plus what is inside the price and what is billed separately. A general capability slide is not evidence for the seal line.
What every rubber cord seal quotation must expose
Write the groove or lid the cord will sit in, even if you will send a drawing later. Length of cord versus finished spliced ring is a different quantity. If the plant quotes by the meter and you need rings, say so before anyone totals freight.
| Field | Must appear on the quote |
|---|---|
| Size reference | Finished diameter, or width × height for square section, in inches or millimetres |
| Length versus ring | Meters of cord, or number of spliced rings with mean diameter |
| Compound and Shore A | Named elastomer and hardness the supplier must confirm |
| Inclusions | Splice, adhesive, vulcanizing film or cut-to-length — inside the price or billed separately |
| Packing and Incoterms | Coils, reels or boxed rings next to the money figure |
| Evidence | Current dimensional page or ASTM method for the quoted item, not a plant brochure |
How this desk issues the same rubber cord seal line
-
Collect the axes you already have
Groove size, compound preference, quantity and destination. Missing fields stay blank. We do not invent a 70 Shore A default or an FDA conclusion to complete the form.
-
Send one list to more than one factory
Each supplier sees the same inclusions and document set. A REACH SVHC statement is requested only when you asked for it, and it must name the quoted grade.
-
Lay replies side by side
Compare total procurement cost on the same quantity, packing and Incoterms. We will not recast a cheaper-looking number on a different scope as a percentage saving.
-
Return substitutions in writing
If a factory proposes strip stock, a molded O-ring or a different compound instead of the rubber cord seal line, the change in section, hardness or file set has to be written down.

Issue the rubber cord seal request as written
Include size, quantity, destination and which accessories sit inside the price. We will not convert a jewelry necklace search into industrial seal stock to complete a cell.
