Precision Sealing Components for Oil & Gas Industry
Kesaria Rubber Industries manufactures precision rubber, FKM (Viton®), HNBR, and PTFE sealing components for the oil and gas industry. FKM O-Rings deliver aggressive chemical and high-temperature resistance in valve and flange assemblies. HNBR Seals and Gaskets are engineered for sour gas resistance in upstream production equipment, accumulator bladders, and diaphragms. NBR O-Rings provide reliable sealing against petroleum oils, crude oil, and gasoline in pipeline fittings. PTFE Gaskets, Washers, and Thread Seal Tape offer chemically inert, non-reactive sealing for high-temperature pipeline and flange connections. With 37+ years of precision moulding expertise and a manufacturing plant in Jamnagar, Kesaria is a trusted sealing partner for oil and gas OEMs and processing units across India and 27+ export markets.
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)
Pressure regulators, gas regulators, and pressure relief valves in oil and gas systems depend on flexible diaphragm seals to maintain accurate pressure control without media leakage. Kesaria manufactures Rubber Diaphragms in NBR, Silicone, EPDM, and Neoprene, applied in oil and gas systems for sealing and flow regulation, as well as electrical and pneumatic control valves, pressure regulators, and high-pressure pumps. Custom-moulded bellows and bushes complement diaphragm assemblies for OEMs building pressure-control equipment for upstream and downstream oil and gas operations.
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
