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.
Perfluoroelastomer (FFKM) O-rings have carbon fluorine bonds, making them one of the most thermally stable, oxidative stable, and chemically stable fluorinated polymers.
Hammer Union Seals are used in hammer union-style pipe connections to establish flow lines and prevent leakage. It is widely used in the oil & gas industry.
SPGO is a low friction piston seal consisting of PTFE+Bronze seal ring and rubber o-ring used for two-way piston seal of Hydraulic cylinder, to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
Spring energized PTFE seals consist of variety of jacket profiles and spring types. It can achieve the sealing effect compensation under different pressure conditions by spring energizer.
High-pressure Rotary shaft seals are one bidirectional rotary seal which can bear both sides of pressure and alternating pressure. It is made with slip ring and o-ring/square ring.
The FDR seal is made of a helical wound spring and a polymer jacket, which is mainly used as a Flange external face seal.
The ID S seal is used for wellheads, downhole tools and surface pressure control equipment as a critial part.
