Piping flanges
Pumps and valves with material and manufacturing support from prototype through repeat production.
gaskets Manufacturer · Direct Factory Supply
JAIFUXIN manufactures and supplies gaskets for industrial buyers that require broad chemical resistance, low contamination and reliable sealing on industrial flanges. Standard sizes, custom dimensions and drawing-based factory processing are available.
Engineering overview
Select gaskets by flange standard, pressure class, media, temperature, bolt load and compliance. Final suitability depends on the complete operating environment and required service life.
Pumps and valves with material and manufacturing support from prototype through repeat production.
Hydraulic systems with material and manufacturing support from prototype through repeat production.
Chemical flanges with material and manufacturing support from prototype through repeat production.
Compressor equipment with material and manufacturing support from prototype through repeat production.
Confirm flange standard, pressure class, media, temperature and thickness. We can review bolt-hole patterns and recommend PTFE, filled PTFE or ePTFE options.

Frequently asked questions
Confirm the resin or compound, manufacturing route, dimensional tolerance, inspection method and batch traceability. The drawing and service conditions should be reviewed before price becomes the deciding factor.
Send the required grade, dimensions, tolerance, quantity, operating temperature, chemical media, mechanical load, documentation and delivery destination. Photos or drawings help prevent quotation assumptions.
Custom dimensions and secondary processing can be reviewed from a drawing, sample or application specification. Feasibility depends on the material, production method, tolerance and order volume.
Teflon™ is a brand name commonly associated with PTFE, while PTFE is the generic polymer name. Buyers should specify the actual resin grade and required properties rather than rely on the trade name alone. See the PTFE material guide.
Virgin PTFE emphasizes chemical resistance, low friction and electrical insulation. Glass, carbon, graphite or bronze fillers can improve selected wear, creep or load properties but also change other characteristics.
Select gaskets by flange standard, pressure class, media, temperature, bolt load and compliance. Final suitability depends on the complete operating environment and required service life.
Samples and prototypes can be reviewed before a production order. Approval criteria should identify critical dimensions, appearance, material grade and any required test records.
Review the PTFE material guide and the fluoropolymer gaskets product range before choosing an alternative.
