Precision Sealing Components for
Plumbing & Bathware Industries

Kesaria Rubber Industries manufacturesapplication-specific rubber, TPE, and PTFE sealing components for the plumbing and bathware industry. Rubber O-Rings in EPDM, NBR, and Silicone grades prevent leakage inside faucets, mixer valves, and shower diverters. EPDM Gaskets seal pipe joints and flanges in water supply and drainage systems. SWR Pipe Seals in TPE ensure long-term performance in soil and rainwater drainage piping. Toilet Seat Gaskets and PTFE Washers deliver leak-free reliability in flushing devices and sanitary fittings. Coated O-Rings and Rubber Seals protect ball valves from stick-slip failure. With 35+ years of precision moulding expertise, Kesaria is the trusted sealing partner for plumbing and bathware manufacturers across India, Europe, and the Middle East.

Bathware Industries

Kesaria sealing components are precision-engineered to meet the exact performance demands of modern bathware — from high-cycle faucet cartridges to thermostatic shower systems and cistern flush mechanisms. Every component is designed for the real-world operating conditions of the bathware industry: hard water mineralisation, thermal cycling, cleaning chemical exposure, and high flush-cycle fatigue.

Rubber Sealing Components

  for Faucets & Mixer Valves

Faucet

Inside every faucet and mixer valve, rubber sealing components determine whether a product leaks, drips, or lasts. Kesaria supplies EPDM O-Rings, NBR Rubber Seals, and Custom-Moulded Rubber Parts specifically engineered for faucet cartridges, quarter-turn ceramic disc seats, and inlet valve assemblies. Our seals maintain consistent compression and dimensional accuracy across thousands of open-close cycles, reducing warranty claims and service callbacks for bathware manufacturers. Available in WRAS and NSF compliant material grades for potable water contact applications in residential and commercial installations.

Key Points :

  • Kesaria EPDM O-Rings for faucet cartridges resist hard water mineral deposits and chlorine exposure without swelling or degrading — the leading cause of faucet drip failure
  • NBR Rubber Seals provide excellent oil and grease resistance for faucet cartridge mechanisms and mixer valve internals, ensuring smooth quarter-turn operation
  • Custom-moulded Rubber Parts are available for OEM faucet manufacturers with non-standard groove dimensions, sealing lips, or compression ratios requiring precision tooling
  • WRAS and NSF certified material grades confirm safety for potable water contact — critical for faucets installed in kitchens, bathrooms, and commercial washrooms
  • All Kesaria faucet sealing components are manufactured using flashless precision moulding, delivering consistent dimensional accuracy and reducing post-moulding rejection rates.

Rubber O-Rings & Seals

for Shower Systems & Mixer Applications

Showers

From concealed thermostatic mixers to overhead rain showers and diverter valves, Kesaria’s sealing components ensure every shower system performs leak-free across thousands of thermal cycles. EPDM O-Rings, Silicone O-Rings, and NBR Rubber Seals for shower cartridges and flow regulators are engineered to withstand the combined demands of hard water, heat cycling, and cleaning chemical exposure — the three primary causes of premature seal failure in bathware applications. Custom-moulded shower seals are available for OEM shower fitting manufacturers requiring non-standard specifications.

Key Points :

  • Kesaria EPDM O-Rings resist repeated hot-cold thermal cycling in shower mixers and diverters, maintaining sealing integrity under daily use conditions across India and the Middle East

  • All shower-grade sealing components comply with WRAS and NSF standards, confirming material safety for potable water contact in residential and hospitality shower installations

Rubber Gaskets, PTFE Washers & Coated O-Rings

for Cisterns & Flush Mechanisms

Flushing Devices

Cistern flush mechanisms, fill valves, and WC flushing devices demand sealing components that maintain reliable performance through thousands of flush cycles, variable water pressures, and continuous exposure to water treatment chemicals. Kesaria manufactures Toilet Seat Gaskets, Rubber Washers in EPDM and NBR, PTFE Washers, and Coated O-Rings for flush valves, float mechanisms, and cistern inlet assemblies — delivering zero-leak performance in both residential WC installations and high-traffic commercial washrooms.

Key Points :

  • Kesaria Toilet Seat Gaskets are precision-moulded to deliver consistent sealing between cistern components and ceramic surfaces, preventing water wastage and costly after-sales service calls
  • Rubber Washers in EPDM, Neoprene, and NBR provide reliable compression sealing in flush valves, fill valves, and cistern inlet fittings across variable water pressure conditions
  • PTFE Washers offer near-zero friction sealing in sanitary shut-off valves and inlet fittings — ideal for chemically treated municipal water supplies where rubber degradation is a concern
  • Coated O-Rings with PTFE or nylon coatings minimise stick-slip friction in cistern ball valves and float mechanisms, extending operational life and reducing maintenance frequency
  • All flushing device components are manufactured to high dimensional accuracy as per international standards, reducing reject rates and warranty claims for cistern and WC brands

Plumbing

Kesaria sealing components form the foundation of leak-free plumbing infrastructure — from threaded pipe connections in residential buildings to high-pressure flanged systems in commercial and industrial installations. Every Kesaria product is engineered for real-world plumbing conditions: static and dynamic pressures, thermal expansion and contraction, soil and waste water chemistry, and long-term UV and chemical exposure in drainage infrastructure.

Rubber Gaskets & PTFE Thread Seal Tape

for Pipe Joints & Flanges

Pipe Fittings

Pipe fitting joints and flanged connections are only as reliable as the gasket or sealant inside them. Kesaria manufactures Rubber Gaskets in EPDM, NBR, Neoprene, Viton®, and Silicone grades for pressure-rated pipe flanges, along with PTFE Thread Seal Tape for threaded pipe connections. Our gaskets are available in a Shore A hardness range of 30–95 Durometer, accommodating everything from low-pressure domestic plumbing fittings to high-pressure industrial water supply systems, in custom shapes and sizes for OEM pipe fitting manufacturers.

TPE SWR Pipe

Seals for Soil, Waste & Rainwater Drainage Systems

Drainage System

In soil, waste, and rainwater (SWR) drainage systems, the pipe joint seal is the critical component determining whether a system remains leak-free over its 25–50 year service life. Kesaria manufactures TPE SWR Pipe Fitting Seals and OPVC Pipe Seals specifically engineered for push-fit and solvent-weld drainage piping. These seals provide flexible, pressure-resistant performance at pipe joints, couplings, and inspection chambers — ensuring long-term leak-free drainagein residential, commercial, and municipal infrastructure.
