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.
Dovetail groove is used to put the O-ring or elastomer dovetail seal during installation. This groove is not common because it is more expensive to machine, but this dovetail groove can avoid seal extrusion out.
The FS-seal is a relatively large cross section spring energized elastomer casing and tubing hanger seal for wellheads that always has the springs on the internal surface.
Piston seals are work to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
We have been manufacturing various types of fluid end valve and seats for both frac pumps and mud pumps, covering various models for the most dominant pumps in the market.
The FDB seal is made of a helical wound spring and a polymer jacket, It is the best choice for vacuum, gas and low-temperature flange sealing applications.
JST's back up ring compensate for large temperature fluctuations. Using Back-up Rings allows O-Rings to be utilized in higher pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. Back-up Rings are protective and supporting elements with no sealing function. The back up ring material could be PEEK, modified PTFE.
Swivel joint ball plug is working together with hammer union seals, to seal the balls of high pressure elbows and grease.
