Flat-profile gasket projects for covers, plates and stationary interfaces, defined by outline, openings and thickness.
Use this family when the sealing element is described by a two-dimensional profile and nominal thickness. The drawing must identify the sealing land, bolt holes and any openings that need to stay clear after assembly.
Provide the assembled gap, surface condition and fastening arrangement. A thicker gasket should not be assumed to correct a damaged or misaligned joint. If replacing an old gasket, record its uncompressed thickness where possible and explain whether it has taken a permanent set.
Material, cut-edge quality, thickness tolerance and supplied flatness need project review. Adhesive backing, if requested, introduces an additional material and should be evaluated for the exposure and removal task.
Treat the used measurement as evidence of condition, not automatically the original nominal thickness. Include the joint drawing or an unused reference if available.
It is a separate requirement to review. Specify whether adhesive contacts the medium and whether clean removal matters.
These references explain general engineering or regulatory context. They are not Xinwei finished-product specifications, test results or compliance evidence.
SPECIFICATION REFERENCE
These are project discussion inputs. Compound, tolerances and validated performance require agreement for the specific part.
| Selection / definition | Reference and project conditions |
|---|---|
| Outline | Dimensioned profile or usable CAD file with units in mm |
| Thickness | Nominal thickness and tolerance in mm; identify free-state condition |
| Openings | Hole diameters/slots and datum positions in mm |
| Joint | Sealing land width, surface condition and fastener layout |
| Exposure | Medium, concentration, temperature in °C and cleaning cycle |
| Acceptance | Edge, flatness, fit and assembled leak criteria |
KNOWLEDGE & SELECTION
Knowledge
A practical procurement guide to the installation details that drawings and material names often miss. Learn what to specify for pump tubing, formed elbows, reinforced hoses, appliance connectors, automotive ducts, closures, flexible seals and gaskets—and where product-family descriptions stop short of proving suitability.

Knowledge
A practical B2B selection guide for separating pump tubing, transfer tubing, formed elbows, reinforced hoses, appliance connections, automotive ducts and molded seals. Learn which application conditions to define, what drawings and evidence to request, and why similar-looking rubber parts should not be treated as interchangeable.
