For a felt component inquiry, the distinction between “gasket” and “seal” is less useful than a clear description of the assembly and required function. Terminology can vary between drawings and suppliers. Neither name establishes fluid-tightness, pressure capability, or suitability for a moving assembly.
Compare the information each inquiry needs
| Question | Gasket-oriented brief | Seal-oriented brief |
|---|---|---|
| Where is it installed? | Identify the mating faces, complete outline, holes, and clearances. | Identify the contact interface, groove, shaft, or other assembly features. |
| What must it do? | Describe cushioning, protection, separation, or the specified interface function. | Describe the intended barrier or contact function and what must be controlled. |
| What affects suitability? | Thickness, compression, contact surfaces, movement, and environment. | Contact conditions, movement, medium, compression, and environment. |
| How is it approved? | Defined dimensional, fit, and functional checks. | Defined fit and functional checks for the actual assembly. |
This is a procurement checklist, not a universal classification. A ring-shaped part can appear under either name; geometry alone does not determine function.
Describe the installed location
Provide a dimensioned drawing and an assembly photo or sketch. Mark the surfaces that contact the felt, how the part is retained, and whether either surface moves. Identify which dimensions are critical to assembly.
State the medium and acceptance criteria
If the part contacts oil, moisture, dust, or a cleaning agent, name it and describe the relevant conditions. If containment or leakage performance is required, provide the requirement and test method for suitability review rather than assuming the word “seal” guarantees it.
Can the same drawing be sent for either review?
You can start with the same drawing, but include the intended function and assembly conditions. State whether the sample is approved or simply a reference. The resulting material and fabrication proposal must address the requirements, regardless of the drawing’s part name.
Prepare the specification before requesting a quote
For a gasket brief, use the eight-detail felt gasket specification checklist. Then organize the known dimensions, working conditions and approval criteria in the custom felt part RFQ template.
Choose the closest inquiry page
Use custom felt gaskets for a gasket brief or custom felt seals for a seal brief. If the terminology is undecided, start with custom felt fabrication and explain the required function through the B2B project inquiry form.
