seals
JAIFUXIN manufactures and supplies seals for industrial buyers that require low friction, chemical resistance, dry-running capability and performance beyond many elastomer limits. Standard sizes, custom dimensions and drawing-based factory processing are available.
Engineering overview
Sealing Performance for Aggressive Service
Select seals by pressure, speed, media, temperature, groove, mating surface and leakage target. Final suitability depends on the complete operating environment and required service life.
Pumps and compressors
Hydraulic systems with material and manufacturing support from prototype through repeat production.
Valves and actuators
Chemical flanges with material and manufacturing support from prototype through repeat production.
Chemical equipment
Compressor equipment with material and manufacturing support from prototype through repeat production.
seals
Match the seal to pressure, speed, media, temperature and groove design. Send your operating conditions or drawing for profile and compound recommendations.

Frequently asked questions
seals FAQ
What should buyers verify when choosing a seals manufacturer?
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.
What information should I send to a seals supplier?
Send the required grade, dimensions, tolerance, quantity, operating temperature, chemical media, mechanical load, documentation and delivery destination. Photos or drawings help prevent quotation assumptions.
Can the JAIFUXIN seals factory make custom sizes?
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.
Is Teflon the same as PTFE?
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.
What is the difference between virgin PTFE and filled PTFE?
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.
How do I select the right seals for my application?
Select seals by pressure, speed, media, temperature, groove, mating surface and leakage target. Final suitability depends on the complete operating environment and required service life.
Can I order samples before repeat production of seals?
Samples and prototypes can be reviewed before a production order. Approval criteria should identify critical dimensions, appearance, material grade and any required test records.
Where can I compare related seals materials and product forms?
Review the PTFE material guide and the custom fluoropolymer seals product range before choosing an alternative.
How do PTFE creep and cold flow affect seals?
Sustained load can deform PTFE over time. Review compressive stress, temperature, support area and whether a filled PTFE grade is needed.
