Silicone Rubber Flange Washer Gasket
Silicone Rubber Washer Gaskets Supplier
A full face silicone rubber flange washer gasket is designed to create a reliable seal between two mating flange connections in piping systems, tanks, pumps, and industrial equipment. Unlike standard ring gaskets, a full face gasket covers the entire flange surface including the bolt holes, ensuring uniform pressure distribution and easy alignment during installation.
Suconvey manufactures custom silicone rubber flange gaskets and sealing washers for industrial applications where durability, chemical stability, and temperature resistance are critical.
Whether you need a silicone flange gasket for pipelines, equipment housings, or flange-mounted components, our products help maintain leak-free operation and long-term system reliability.
Silicone Rubber Flange Washer Gasket
A full face silicone rubber gasket is a sealing washer-style gasket designed to fit the entire flange surface. The gasket includes bolt holes and covers the entire contact face, allowing compression forces to distribute evenly across the sealing area.
When the flange bolts are tightened, the silicone rubber gasket compresses between the two flange faces, creating a seal that prevents leakage of fluids or gases from the pipeline system.
Compared with smaller ring gaskets, full face gaskets provide:
easier installation
better alignment
uniform sealing stress
reduced risk of flange distortion
This design makes them widely used in low-to-medium pressure industrial piping systems.

Why Customers Choose Silicone Rubber Flange Gaskets?
Reliable Sealing Performance
Silicone rubber is highly elastic and compressible. When compressed between flanges, the gasket expands slightly and forms a tight seal that prevents leakage.
Wide Temperature Resistance
Silicone materials maintain sealing performance across extreme temperatures and environmental conditions, making them suitable for both cold and high-temperature systems.
Excellent Chemical Stability
Silicone rubber gaskets resist many oils, solvents, acids, and industrial chemicals, allowing them to perform reliably in demanding environments.
Long Service Life
Silicone rubber resists UV exposure, ozone, moisture, and weathering, which helps extend the service life of the flange gasket in both indoor and outdoor systems.

Typical Applications
Full face silicone rubber flange gaskets are commonly used in:
industrial pipeline connections
pump and valve flange sealing
water treatment systems
chemical processing equipment
HVAC duct and piping systems
food processing equipment
pharmaceutical and laboratory piping
In many systems, the gasket also acts as a sealing washer between flange bolts, improving sealing consistency and preventing leakage around the flange joint.
Silicone Rubber vs Standard Rubber Flange Gaskets
Customers often ask whether to choose silicone rubber gaskets or traditional rubber materials.
Silicone offers advantages in environments where temperature stability and environmental resistance are important.
Compared with many standard rubber materials, silicone gaskets provide:
superior heat resistance
better UV and ozone resistance
longer service life
stable flexibility over time
This makes silicone flange gaskets ideal for outdoor equipment, high-temperature processes, and equipment exposed to harsh environments.

Packaging & Shipping Information
To protect the product during global transportation and storage, we apply export-grade packaging and provide flexible shipping solutions.
Pre-Shipment Inspection
Each batch is inspected before packaging to confirm hardness, thickness, surface condition, and visual uniformity. Batch codes are recorded and compliance documentation may be provided when required for regulatory purposes.
Packaging Method
Silicone gaskets are wrapped with protective film to prevent dust, moisture, and surface damage. Several rolls are placed into reinforced cartons, which are then secured on fumigation-free pallets using straps and stretch film.
Shipment Options
We regularly ship to customers in Europe, North America, and Asia through sea freight, air freight, or express courier for urgent testing needs. Both FCL and LCL shipments are available.
Documentation Support
All necessary export documents can be provided for customs clearance, including commercial invoice, packing list, bill of lading or airway bill, certificate of origin, and food-contact compliance statements or test reports when applicable.
Sample Delivery
Material samples and short test gaskets can be supplied for validation and equipment trials. Samples can be sent via DHL, FedEx, UPS, TNT, or using your appointed courier account.
After-Arrival Support
