The "VPT" LLC is the leading enterprise that produces GMRG. The firm offers its clients more than 900 kinds of products. There are four manufacturing blocks and over 600 workers there. The enterprise uses only up-to-date technologies according to all European quality standards.
They are used for pressure feed of water, lubricating liquids, diesel oil, solid oil, inorganic acids weak liquid, motor petrol, jet engine fuel, antifreezing cooling fluid, aviation petrol, petroleum-based oil, alkalis (up to 20%), except nitric acid.
These flexible conduits are made for the pressure feed of air, inert gas, different fluids. The safety factor for liquid operating environment is 3P, and for air and other gases is 5P.
The sleeves are operable in areas with a moderate, tropical or frigid climate under temperature of -50 up to + 90 degrees centigrade.

They are destined for the pressure feed of such substances as:
the first category: acetylene, propane, butane under pressure 0,63 MPa.
the second category: liquid fuel such as petrol а-72, white spirit, kerosene under pressure 0,63 MPa.
the third category: oxygen under pressure 2 MPa and 4 MPa.
From -35°С up to +70°С – for a moderate and tropical climate
From -55°С up to +70°С – for a frigid climate
The safety factor is 3P.

4. Curved hoses of radiator engine cooling systems (technical specifications 2556-001-22465588-2008)
These hoses are made for transmission of cooling fluid such as water or antifreeze. The clad hoses are right for using in areas with a moderate or tropical climate with different humidity and under the temperature of – 50 up to + 90 °C.
The hoses can be of two types:
I Ones with a lining
II Braided ones
