Rubber Gaskets
A rubber gasket is a smart component that seals against both liquids and gases. They are the perfect solution to fill in irregularities and connect two surfaces together. The characteristics of a gasket are to be manipulable and able to warp into the tight space it is designed for.
Types Of Rubber Gaskets :
Neoprene
Rubber Gaskets
exhibit good chemical inertia, and are commonly used in electrical installations and weather sealing applications. Popular examples of gaskets made from neoprene are:
● Transformer Gaskets
● Manway Gaskets
These joints are particularly suitable for use with water; be that salt or fresh water – although from drinking (potable) water it is better to use EPDM rubber.
Neoprene has good resistance to ozone and sunlight. It does not support combustion, but self extinguishes. It has a resistance to oils, and is ideally used in temperatures ranging from -20 C to +110 C
EPDM
Rubber Gaskets
used in anti-vibration, sealing, and electrical insulation applications.
These parts are widely used in the water industry, are WRAS approved, and suitable for use with potable drinking water.
EPDM is short for ethylene propylene diene monomer rubber.
Popular examples of gaskets made from EPDM are:
● Standard Pipe Gaskets
● Pump Gaskets
Nitrile
Rubber Gaskets
are particularly suited for use with fats, oils, fuels, and other liquids contaminated by
these; they can also be used at a range of temperatures (-40c to +120c depending on grade). Nitrile is also known as Buna-N, Perbunan, or NBR rubber.
Popular examples of gaskets made from nitrile are:
● Oil Gaskets
● Cover Gaskets
Silicone
Rubber Gaskets
are known for their chemical inertia and as such are useful in extreme
environments, and temperatures from -55°C to +300°C.
Popular examples of gaskets made from silicone are:
● Food Quality Gaskets
● Pharmaceutical Quality Gaskets
Remember that as a general rule you should select the thinnest gasket possible for your application.
Viton
Rubber Gaskets
are used in the presence of aggressive chemicals, fuels, and explosive
gases; and as such as application in the oil, gas, and mining industries.
