50Rubber V Packing hydraulic seal
VT type V Packing is widely used for sealing pistons and rods with both single and double acting cylinders. It has multiple lip seals including a male and female adaptor on the top and bottom of the set to provide a flat surface, and 5 V-shaped pressure rings (3 fabric reinforced seals, 2 rubber seals). The number of pressure rings determines the amount of pressure they will contain, which are mainly for sealing.
V-packing is commonly used in adjustable gland applications such as telescopic truck cranes, pumps and valves. When strict chemical, temperature or pressure requirements are involved, the material composition of V-packing set can be changed to meet the application requirements. It can provide good sealing effect. They are very robust, insensitive to sealing surface finish and adjustable in size, especially for applications where there is a risk of damage and contamination.
The materials of the V packing define the capability of abrasion, friction, temperature and pressure resistance.
According to the specific application, we offer NBR, HNBR, FKM, various fabric layers, as well as PTFE.

Advantages: 1. Impact resistance; 2. Multi-lip seal, excellent sealing performance; 3. Adjustable preload to improve sealing; 4. Not sensitive to media contamination. |

V Packing consist of multiple male and female adaptor, usually a group of three to seven v rings, used for low or high pressure applications with Single or Double acting cylinder.
FFKM O-ring is a circular seal made of perfluoroelastomer compound, with a higher fluorine content than FKM fluoroelastomer.
Outer wireline valve seals are used in various type of Blow Out Preventors (BOP's).
JST's Inner and Outer BOP Seals could be made according to customer requirements. These seals are used in various type of Blow Out Preventors (BOP's).
V-Packings are used in various Oilfield Downhole equipment such as various Valves etc. V-Packings are extremely suitable for usage in medium to heavy duty applications. Vee Packings accept low and high pressure while operating in the most extreme conditions and also if there exists any misalignment between the sealing gaps.
A glass filled nylon wear ring, also called wear band, offers high bearing load capacity over a broad range of temperatures.
Rotary shaft seals with PTFE ring have been specially developed for use in harsh conditions. They are used when shaft seals with classic elastomer lips reach their performance limits.
Back-up Ring/Anti Extrusion Rings is a ring that holds an elastomeric seal to its outline shape and in its right place. and are typically used with O Rings to eliminate extrusion at high pressures.
