Voltomach Seals Engineering Pvt. Ltd.

An NBR Rubber Washer is a sealing ring made from Nitrile Butadiene Rubber, prized for its excellent resistance to oils, fuels, and chemicals, making it ideal for automotive, industrial, and hydraulic uses to prevent leaks and absorb vibration. These flat, circular components provide a tight seal and come in various sizes, thicknesses, and hardnesses, acting as spacers, wear pads, or vibration dampeners in machinery. 

Silicone rubber washers are versatile components used for sealing, cushioning, and electrical insulation across many industries due to their excellent temperature resistance and durability. 

Viton rubber washers (also known as FKM) are high-performance sealing components known for their exceptional resistance to high temperatures, chemicals, oils, and fuels. They are primarily used in demanding industrial applications, offering durability and reliable sealing in harsh environments.

EPDM rubber washers are durable, weather-resistant sealing and cushioning components available in various sizes and types, including flat and bonded stainless steel options, from suppliers like BCP Fasteners, SHKIBY, and various local manufacturers in India. They are widely used in roofing, plumbing, and automotive applications due to their high resistance to UV, ozone, water, and temperature variations.

Nitrile rubber washers, made from Nitrile Butadiene Rubber (NBR or Buna-N), are durable sealing components known for their excellent resistance to oils, fuels, and chemicals. They are widely used in automotive, industrial, and plumbing applications to create tight seals and prevent leaks
