Item No. RGS-013
Rubber flange gasket serve as critical sealing components for flange connections on pipes, valves and pumps across diverse industrial systems. These full‑face style gaskets come with pre‑drilled mounting holes to perfectly fit standard flange specifications, eliminating on‑site secondary cutting or hole‑punching and simplifying field installation.
Manufactured from high‑quality synthetic rubber including NBR, EPDM, neoprene CR and FKM fluoro‑rubber, they deliver reliable sealing under varying working pressure. With good elasticity, excellent compression‑set resistance and superior anti‑aging property, the gaskets compensate minor surface irregularities on flange mating faces to block liquid and gas leakages.
Different material grades adapt to water, oil, weak chemicals and harsh outdoor environments, widely applied in plumbing, water‑treatment, petrochemical and general mechanical equipment. OEM & custom manufacturing is supported. We can produce gaskets strictly according to your technical drawings or physical samples for all kinds of industrial sealing requirements.
Key Features of Rubber Flange Gasket.
1. Precision Full‑Face Structure with Pre‑Drilled Bolt Holes
Full‑face design with pre‑punched mounting holes that precisely match standard flange hole patterns. No secondary on‑site cutting or drilling required, enabling fast, accurate assembly for pipe, valve and pump flange joints.
2. Multiple Premium Rubber Material Options
Available in NBR, EPDM, Neoprene CR and FKM fluoro‑rubber. Selectable formulations cater for oil resistance, hot‑water resistance, weather ageing resistance and chemical resistance to match different working media.
3. Excellent Elasticity & Compression‑Set Resistance
Superior rubber elasticity allows the gasket to conform to minor surface imperfections on flange mating faces. Low compression‑set performance maintains stable sealing force under continuous pressure, effectively stopping liquid and gas leakage.
4. Broad Media & Environment Compatibility
Resistant to water, lubricating oil, mild acids, alkalis and UV outdoor exposure. Performs steadily across plumbing, water‑treatment, petrochemical and general‑purpose industrial working conditions.
5. Long‑Term Durability & Anti‑Ageing Performance
High‑grade synthetic rubber formula delivers great anti‑aging, anti‑oxidation performance. Resists degradation under long‑time pressure and temperature cycling, extending service life of flange connection systems.
6. Full OEM & Customization Capacity
Custom inner diameter, outer diameter, thickness, bolt hole quantity and hole layout are acceptable. We can manufacture strictly based on your technical drawings or physical samples for non‑standard flange sealing demands.
Applications of Rubber Flange Gasket.
Rubber flange gaskets are widely‑used sealing elements for bolted flange joints, providing leak‑proof sealing for liquid, gas and semi‑fluid media across numerous industries.
1. Water Supply & Drainage Systems
Ideal for potable water pipelines, sewage treatment pipes, water tanks and pumping stations. EPDM rubber flange gaskets perform well for cold and hot water circulation, resisting moisture and long‑term water immersion.
2. Petroleum & Oil‑Related Equipment
NBR rubber flange gaskets are commonly applied for oil pipelines, fuel transfer pumps and oil‑medium valves. They offer reliable sealing against hydraulic oil, lubricating oil and various petroleum‑based fluids.
3. Chemical & Light‑Industrial Facilities
Suitable for pipelines transporting weak acid, weak alkali and general chemical solutions. Neoprene CR and FKM fluoro‑rubber grades are selected according to medium corrosiveness for reactor and process‑pipe flange connections.
4. General Mechanical & Industrial Equipment
Used for flange sealing on industrial pumps, valves, compressors, heat exchangers and pressure vessels. Compensates minor flange surface unevenness to prevent medium leakage under working pressure.
5. Outdoor & Marine Working Conditions
Weather‑resistant formulations resist UV radiation, ozone and temperature fluctuations. Fit for outdoor pipeline projects, on‑site process equipment and some marine piping systems.
6. Custom Non‑Standard Flange Projects
Custom‑made rubber flange gaskets per drawings or samples serve special‑dimension equipment, skid‑mounted units and special‑purpose machinery with non‑standard flange sizes.
Material
NR, EPDM, NBR, CR, SBR, Silicone, FKM.
Hardness
30 ShA – 90 ShA
Color
OEM colors according to RAL or Pantone No.
Size
OEM sizes according to customer’s requirement.
Logo
Customized logo according to customer’s need.
Standard: Goods are typically supplied in about 20-25kg/carton.
Standardized Pallets: Goods are stacked on heat-treated (ISPM 15) or plastic pallets, optimized for forklift handling. Rigid Corner Protectors: High-impact cardboard corner guards are applied to the full height of the stack. This prevents the straps from cutting into the rubber and maintains the vertical integrity of the pallet.
How to choose the material for rubber flange gasket?
NBR for oil; EPDM for water & outdoor; FKM for high‑temp & chemicals; CR for general‑purpose sealing.
Do you support custom rubber flange gasket?
Yes. Custom ID, OD, thickness and bolt hole patterns per drawings or samples.
What details for quotation?
Size, material, working medium & temperature, order quantity.
Can I reuse used flange gasket?
Not advised. Replace with new gaskets after disassembly to avoid leakage.
Why gasket leaks?
Wrong material, uneven flange face, improper bolt torque or aged gasket.
What is your MOQ for rubber flange gasket?
For standard in‑stock sizes, small trial orders are acceptable. For custom‑made non‑standard gaskets, MOQ depends on dimension and tooling requirement. Contact us to get flexible MOQ solution for your project.
