Precision Sealing Components for Oil & Gas Industry
Valves & Flow Control Equipment
Ball valves, gate valves, and pressure regulators in oil and gas systems demand sealing components engineered for aggressive hydrocarbons, sour gas, and wide temperature swings. Kesaria supplies FKM (Viton®) O-Rings, NBR O-Rings, and HNBR Seals for valve seats, stem seals, and actuator assemblies. FKM compounds resist oils, fuels, lubricants, and most mineral acids at elevated temperatures, while HNBR handles sour gas and mineral oil-based hydraulic fluids without degrading — making both materials the standard choice for upstream and midstream valve manufacturers requiring zero-leak, long-service-life shut-off performance.
Key Points :
- FKM/Viton® O-Rings offer excellent resistance to heat, oils, fuels, and chemicals, with service life above 200°C - ideal for high-temperature valve sealing in oil and gas processing
- HNBR Seals and Gaskets resist sour gas, mineral oil-based hydraulic fluids, and diesel fuel, with a working range up to +150°C, commonly used in oil and gas gaskets, seals, and accumulator bladders
- NBR O-Rings deliver strong resistance to petroleum-based oils, fuels, and hydraulic fluids in valve and flow-control applications operating between –30°C and +120°C
- Coated O-Rings with PTFE or nylon coatings reduce stick-slip friction in ball valve stem seals and seat rings, lowering operating torque and extending valve life
- Custom sizes from 3mm to 500mm and Shore A hardness from 30 to 90 Durometer are available for OEM valve manufacturers
Pipeline, Flange & Fitting Connections
Pipeline joints, flanged connections, and threaded fittings in oil and gas infrastructure rely on gaskets and tapes that hold their seal under high pressure, temperature cycling, and chemical exposure. Kesaria manufactures Rubber Gaskets in EPDM, NBR, Viton®, and Silicone grades, alongside PTFE Gaskets and PTFE Thread Seal Tape , for flanged pipe joints and threaded connections used in chemical processing and oil and gas piping systems. These components are supplied in custom shapes and sizes to meet DIN/ANSI and customer-drawing specifications for OEM pipeline equipment manufacturers.
Key Points :
- Rubber Gaskets are widely used across bathroom fitting, chemical processing, oil and gas, and piping/plumbing applications, offering resilience under pressure and mild-to-aggressive chemical environments
- PTFE Gaskets and Washers are chemically inert and non-reactive, ideal for oil and gas and high-temperature applications where standard rubber compounds cannot perform
- PTFE Thread Seal Tape provides airtight, watertight sealing on threaded pipe connections, widely used in gas lines and industrial pipefitting
- Gaskets available in Shore A hardness 30–95 Durometer, covering low-pressure fittings through high-pressure industrial flange systems
- Custom ring gaskets, full-face gaskets, and profile seals manufactured per DIN/ANSI standards and customer drawings
Pressure Regulation & Flow Control (Diaphragms & Bellows)
Key Points :
- Rubber Diaphragms act as flexible membranes that permit pressure transmission while blocking liquid or gas passage - core components in gas regulators and pressure relief valves
- Available in NBR, Silicone, EPDM, and Neoprene, selected by chemical compatibility and temperature range for each oil and gas application
- Used across pressure regulators, high-pressure pumps, and gas regulators in oil and gas flow-control systems
- Custom diaphragm profiles and thicknesses manufactured to OEM drawings for pressure-control equipment manufacturers
- Complementary Bellows, Bushes, and Custom Moulded Parts available for complete valve and regulator assemblies

Kesaria supplies FKM (Viton®) O-Rings, HNBR Seals and Gaskets, NBR O-Rings, PTFE Gaskets, PTFE Thread Seal Tape, and Rubber Diaphragms for valves, pipeline flanges, and pressure regulation equipment in oil and gas systems.
FKM (Viton®) O-Rings are preferred for high-temperature, aggressive-chemical oil and gas valve applications, offering resistance above 200°C. NBR O-Rings are suited to standard petroleum oil and fuel contact, while HNBR handles sour gas exposure.
Yes. Kesaria manufactures Rubber Gaskets in EPDM, NBR, Viton®, and Silicone, along with PTFE Gaskets, for flanged pipe joints in chemical processing and oil and gas piping systems, in custom shapes to DIN/ANSI standards.
PTFE is chemically inert and non-reactive, making it ideal for oil and gas and high-temperature applications where standard rubber compounds cannot perform, particularly in gaskets, washers, and thread seal tape.
Yes. HNBR resists sour gas, mineral oil-based hydraulic fluids, diesel fuel, and bio-oils, making it a standard material for gaskets, seals, accumulator bladders, and diaphragms in oil and gas equipment.
Yes. Kesaria manufactures O-Rings from 3mm to 500mm and gaskets from 30–95 Shore A Durometer, with custom compounds, dimensions, and profiles available for OEM oil and gas equipment manufacturers.
