Gasket
Custom Gasket Manufacturer
Chaoyue manufactures custom gaskets in different materials, profiles, thicknesses, and dimensions for specific sealing requirements. We produce flange gaskets, full face gaskets, and other rubber sealing components based on customer drawings, samples, or specifications, with options for material, hardness, and geometry customization.
From sample development to volume production, Chaoyue supports OEM and bulk orders with controlled manufacturing and inspection processes, helping customers maintain consistent gasket dimensions and specifications across repeat orders.

Gasket Types, Materials & Customization Options
| Gasket Type | Construction / Material | Key Characteristics | Typical Sealing Conditions | Common Configurations |
|---|---|---|---|---|
| Rubber Gaskets | NBR, EPDM, FKM, Silicone and other elastomers | Flexible, compressible, good elastic recovery | Water, air, oils, selected chemicals, general industrial media | Flat, ring, custom profiles |
| Flange Gaskets | Rubber, PTFE, graphite, fiber, or other gasket materials | Designed to seal between mating flange faces | Piping, valves, pumps, equipment connections | Full face, ring, custom flange profiles |
| Non-Metallic Gaskets | Rubber, PTFE, graphite, fiber and other soft materials | Conformable sealing surface with low structural weight | Pipes, flanges, equipment joints, general sealing | Flat, full face, ring, custom shapes |
| Semi-Metallic Gaskets | Metal combined with graphite, PTFE, or other fillers | Metal reinforcement with a compressible sealing layer | Higher pressure and temperature flange connections | Spiral wound, kammprofile, metal-jacketed |
| Metallic Gaskets | Stainless steel, carbon steel, alloy steel and other metals | High mechanical strength and resistance to demanding conditions | High-pressure and high-temperature service | Ring, lens, oval, octagonal, custom profiles |
| Spiral Wound Gaskets | Alternating metal winding and filler material | Controlled compression, resilience, and recovery | Flanges, valves, piping under elevated temperature or pressure | Standard flange sizes, custom dimensions |
| Ring Type Joint Gaskets | Precision-machined metal | Metal-to-metal sealing with controlled contact surfaces | High-pressure RTJ flange connections | Oval RTJ, octagonal RTJ |
| Custom Gaskets | Material selected according to requirements | Customized geometry, dimensions, thickness, and material | Non-standard equipment and specific sealing conditions | Die-cut, molded, machined, special profiles |
Gasket Materials & Construction Types
Select the gasket construction according to pressure, temperature, sealing medium, and flange conditions.
Non‑Metallic Gaskets:
- Rubber/Elastomers: Nitrile (Buna‑N), EPDM, Neoprene, Silicone, Viton®. Good for low‑to‑medium pressure/temperature; excellent chemical resistance.
- Compressed Fiber/Non‑Asbestos: Aramid, glass fiber, cellulose. General‑purpose; cost‑effective.
- PTFE (Teflon): Exceptional chemical resistance; low friction; suitable for corrosive media.
- Cork: Resilient; oil/fuel compatible; automotive/general sealing.
Semi‑Metallic Gaskets:
- Spiral Wound: Metal strip (stainless steel) + filler (graphite/PTFE). High resilience; ideal for high‑pressure/temperature and thermal cycling.
- Metal Jacketed: Metal outer shell + soft inner core. Combines metal strength with soft sealing.
Metallic Gaskets:
- Ring Joint (RTJ): Octagonal/oval; metal‑to‑metal seal; ultra‑high pressure/temperature (oil/gas, refineries).
- Kammprofile/Serrated: Serrated metal core; excellent for high‑pressure and vacuum.
- Solid Metal: Copper, aluminum, stainless steel; extreme conditions; requires smooth flanges.
FAQ
Q: What is a Gasket?
A: A gasket is a deformable mechanical seal placed between two mating surfaces to prevent fluid or gas leakage, compensate for surface irregularities, and isolate vibration or corrosion.
Q: What Are the Core Functions of a Gasket?
A: Leak prevention: Block fluid/gas escape or ingress.
Surface compensation: Fill flange imperfections.
Vibration dampening: Absorb shock and reduce fatigue.
Thermal/pressure resistance: Maintain seal under extreme conditions.
Corrosion isolation: Prevent galvanic corrosion between dissimilar metals."
Q: How Do I Choose the Right Gasket?
A: Check 5 key factors:
Media: Chemical compatibility.
Temperature: Max/min operating temp.
Pressure: Static/dynamic pressure.
Flange type & finish.
Environment: Vibration, thermal cycling."
Q: Why Do Gaskets Fail?
A: Wrong material for media/temp/pressure.
Poor installation: dirty flanges, uneven torque.
Compression set & creep relaxation.
Thermal cycling & vibration.
Chemical degradation."
Q: Gasket Storage Tips
A: Cool, dry, dark environment.
Keep flat, avoid bending/folding.
Keep away from chemicals, moisture, sunlight.
