Why Kesaria

Why Automotive Manufacturers Choose Kesaria

Automotive sealing is a zero-failure discipline. A single seal failure in an engine, fuel system, or hydraulic circuit can trigger warranty claims, field recalls, & brand damage. Kesaria’s precision moulding technology, application-specific material selection, & strict quality controls make it the preferred sealing partner for automotive manufacturers who cannot afford failure.

Flashless Precision Moulding

Every automotive sealing component is produced using flashless moulding technology, delivering consistent dimensional accuracy & eliminating post-moulding rejection – critical for high-volume automotive supply chains.

Application-Specific Material Grades

NBR for engine oil & fuel, EPDM for coolant systems, Viton® for aggressive chemical environments, & PTFE for low-friction sealing – Kesaria matches the material to the automotive application, not the other way around.

Custom OEM Tooling

Viton® (FKM) O-Rings and Seals

For turbocharged and high-performance engines, Viton® (FKM) seals provide exceptional resistance to elevated exhaust temperatures, blow-by gases, & aggressive synthetic engine oils under demanding operating conditions.

Custom-Moulded Rubber Parts

Custom-engineered sealing components are developed for OEM applications requiring non-standard geometries, multi-lip sealing profiles, or precise compression load specifications defined by engine design & assembly teams.

Flashless precision moulding

Advanced flashless moulding technology ensures tight dimensional accuracy across every sealing component, helping manufacturers reduce assembly-line rejection rates & minimize long-term sealing-related warranty costs.

Viton® O-Rings, Coated O-Rings

& PTFE Seals

Fuel Systems & Transmission Sealing

Fuel systems and transmission assemblies represent the most chemically demanding sealing environments in the modern automobile. Kesaria supplies Viton® (FKM) O-Rings, NBR Seals, Coated O-Rings, & PTFE Moulded Parts for automotive fuel injectors, fuel pump assemblies, fuel filter housings, automatic transmission fluid (ATF) circuits, gear shift housings, and torque converter assemblies. Viton® O-Rings resist petrol, diesel, ethanol-blended fuels, & aromatic hydrocarbons that degrade standard NBR compounds over time.

For transmission sealing, PTFE-Coated O-Rings reduce stick-slip friction in ATF-lubricated circuits – extending transmission service life & reducing shift-quality deterioration. Custom compound formulations are available for automotive OEM fuel system and transmission engineers requiring non-standard fuel compatibility or long-drain-interval ATF resistance.

Key Points :

Viton® (FKM) O-Rings

Engineered for demanding fuel system environments, Viton® (FKM) O-rings deliver outstanding resistance to petrol, diesel, ethanol blends (E10–E85), & aromatic hydrocarbons that can rapidly degrade conventional sealing compounds like NBR.

NBR O-Rings and Seals

Offering dependable performance with petroleum-based ATF fluids & mild fuel-contact conditions, NBR sealing solutions are widely used in high-volume automotive applications where durability & cost efficiency are equally important.

Coated O-Rings

PTFE & nylon-coated O-rings help minimise stick-slip friction in automatic transmission bore seals & fuel injector assemblies, supporting smoother shifting performance and reducing long-term wear within injection systems.

PTFE Moulded Parts

With exceptional chemical inertness & ultra-low friction properties, PTFE moulded components are ideal for fuel shut-off valves, fuel rail end caps, & transmission hydraulic control valve bodies requiring long-term fluid compatibility and sealing reliability.

All Kesaria fuel & transmission sealing components are available in custom sizes & compound grades for OEM automotive manufacturers, with in-house precision tooling & conformance to international fuel system sealing standards

NBR O-Rings, Rubber Gaskets, Grommets

& PTFE Seals

Hydraulic, Braking & Electrical Systems

Automotive hydraulic braking systems, power steering units, hydraulic clutch assemblies, and vehicle electrical systems rely on Kesaria’s NBR O-Rings, Rubber Gaskets, PTFE Seals, & Rubber Grommets to prevent fluid loss, protect wiring, & isolate vibration in safety-critical applications. Brake caliper piston seals, master cylinder seals, and ABS modulator O-rings must maintain leak-free integrity across thousands of braking events, variable pressure cycles, and extremes of temperature.

Rubber Grommets protect wiring harnesses, sensor cables, & hydraulic hose pass-throughs from heat, vibration, & mechanical abrasion in the engine bay and underbody. Custom compound grades and geometries are available for automotive electrical and hydraulic system suppliers requiring tailored performance specifications.

Key Points :

NBR O-Rings and Rubber Seals

Designed for brake calipers & master cylinder assemblies, NBR sealing solutions deliver reliable performance under high hydraulic pressure, fluctuating temperatures, & continuous exposure to DOT brake fluid formulations.

PTFE Seals and Moulded Parts

PTFE components provide exceptional chemical resistance, ultra-low friction, & extended operational life in power steering valve assemblies & ABS modulator housings operating under high-pressure hydraulic conditions.

Rubber Gaskets in EPDM and NBR

Engineered to maintain sealing integrity in demanding braking systems, EPDM & NBR gaskets are widely used in hydraulic control units, reservoir covers, and pressure accumulator assemblies for ABS & electronic stability control systems.

Rubber Grommets in EPDM, NBR, and Silicone

Manufactured in EPDM, NBR, & silicone compounds, rubber grommets help protect wire harnesses, sensor cables, hydraulic lines, & vacuum hose pass-throughs against heat, vibration, & abrasion in underbonnet and vehicle body applications.
