GENERAL PURPOSE TUBES

The general purpose tubes and hoses are used for the general purposes which do not require high range of purity of the compound. These are mostly used in many domestic appliances and in the workshops or hobby applications because of their excellent flexibility.

MEDICAL/FOOD GRADE TUBES

These are specially designed hoses and tubes which are made in a manner so that they do not react with any medical or food material. They are sterilized in standard autoclaves in order to make them fit for the application in which they come in close contact with the food ingredients, body tissues and fluids or sensitive drugs. In this particular type of tubing the manufactured silicone tubes and hoses are completely tasteless, odorless, and non-toxic with a special property which does not support bacterial growth.

The high pressure tubes and hoses are made by strengthening their composition with wire or polyester braids which combats expansion and flattening. These tubes are mostly used when then the tubes are in direct contact with pressurized gases or suction is conducted. However, sharp edged clamps and fitting should be avoided near the tubes as they have low tensile strength and resistance to steam which may cause excessive wear and tear.

USES OF SILICONE TUBES IN THE INDUSTRIAL SECTOR

Silicone has a multiple usage in the industrial sector because of its excellent properties and types which provide a very wide area for functioning. Some of these uses are:

Rubber Seals Manufacturer and Supplier

Elastomer is a long chain of polymers which are cross linked together by the process of vulcanizations. These elastomers or rubbers are used to make a variety of materials which we use in our regular day to day life. One such important compound is the rubber seals which are manufactured using a variety of rubber types based on the requirements and specifications posed by the consumer or the customer.
TYPES OF RUBBER USED FOR MAKING RUBBER SEALS
Many types of rubber are used for the seal making process. However, the most famous and widely used are

DESCRIPTION THE RUBBER TYPE SEALS
The rubber seals can be manufactured using the three above mentioned types of number. Their description and uses are given below:
• EPDM
The seal made of EPDM is black in color. These seals are mostly used in the rain water and waste water installations where there is no contact of the seal with petrol or oil residues in the water.
• NBR
The NBR seals are also black in color with a yellow spot to differentiate them. These seals can be used in waste and rain water installations where the residue is made up of oil or petrol. These are also used in gas stations, garages and petrol pumps.
• FPM
The FPM seals are purple in color and can be used over a variety of applications. The material seals are particularly heat resistant and oil resistant. They also show strong resistance towards strong acids and solvent. However, they have only a very limited resistance towards butyl acetate, acetone and methyl alcohol.
• TEMPERATURE RANGE CHART

We manufacture a wide range of rubber seals that are manufactured using premium grade material such as silicone, viton, neoprene, nitrile, epdm, butyl, SBR, natural, polyurethane, hypalon, poly acrilic and many others. Precisely designed these seals have gained lots of recognition in the market for their exclusive features.
