V-rings are used for sealing rods and cylinders of hydraulic
equipment with a diam. of up to 2,000 mm and operating under
pressures of up to 63 MPa with a reciprocal motion speed of up to 3
m/sec. in media such as mineral oil, petroleum, fresh and sea
water, aqueous emulsions at a temperature of -50 to +100 °Ñ.
V-rings can be fabricated from fluoroplastic blanks by
This type of sealing rings is intended for heavy duty
operation in any media, except molten alkali metal solutions,
trifluorochlorine and elementary fluorine.
V-rings are to be used in a set with pressure and bearing
rings. The complete sealing set consists of V-rings, one bearing
ring and one compression ring.
Bearing and compression rings are normally made of the same
material as V-rings. The number of V-rings in the sealing set
depends on the operating temperature and pressure in the point of
To achieve improved strength of the seal in a heavy-duty and
high-pressure operational environment, it is desirable to use
fluoroplastic V-rings made from the F4Ê15Ì5 compound.
