The gap between the multiple parts in the hydraulic cylinder is closed with Hydraulic cylinder piston seals. The scheme consists of two primary kinds of hydraulic seals, dynamic seals: they screen in relative motion between parts. The rod sealing scheme screens dynamic reciprocal movement between the roller and head in a hydraulic cylinder. The piston screening scheme screens dynamic reciprocal movement between the column and the cylindrical bore.
Static seals:
They are sealed without relative movement between parts fixed together. Depending on design and building, hydraulic cylinders use static seals in different positions. Static sightings are most prevalent from the piston to the piston rod and from the tube of the head to the bore. Each dynamic Hydraulic and Pneumatic seals has a specific feature for the efficiency of the system in a hydraulic cylinder:
Piston seal:
Serve as a pressure barrier, preventing fluid from passing through the piston. It is essential to control the cylinder movement or keep the stance when standing
Rod seal:
Hydraulic seals and supplies say that it acts as a pressure barrier and maintains the working fluid in the bottle, control that liquid movie extends to the surface of the piston rod – important for inhibiting the rod corrosion and lubricating the wiper seal.
Buffer seal features:
Protect the rod seal against fluid pick-ups over system pressures to minimize system pressure changes and thus enhance the rod seal efficiency through a steady or progressively altering rod seal, which acts as an external exclusion in order to prevent the damage to the roll seal from contaminating the system, such as material particles.

Vee Packing:
Hydraulic cylinder piston seals provide a variety of packaging for packing applications. Thes Hydraulic Seals & Pneumatic Seals sets are generally referred to as Vee or W packaging, and the pressure rings are made of top and bottom fits. The complete configuration drives each set composed of several rings and the pressurization rating of these sets.
Rod Seal U-Cups-Asymmetric Rod Seal:
A range of forms and materials are included in non-symmetric U-Cup models for the linear rod application. Hydraulic seals and supplies have the required profiles and material selection, such as single lip U-Cups, Twin Lip U-Cups, Rod Seals with and without anti-extrusion rings. The materials used on these asymmetric rod stitches are of highly saturated Nitrile (HSN, HNBR), Nitril (Buna-N), PTFE (Teflon), or Urethane, and include ethylene propylene (EPM, EPDM, EPR), fabric & rubber.
Piston Cups:
Piston Cup seals for Hydraulic and Pneumatic seals or plungers. Typically, homogenous piston cups are used for pneumatically, Hydraulic Fluids & Water use in low-pressure applications (less than 150 PSI). Fabric strengthened column cups are usually used in pressurized applications of up to 1000 PSI or in applications with a greater extrusion gap. Also generated by Wiper seal for Hydraulic cylinder was a series of double-acting cups of pistons (PCD piston cups), replacing several assemblies. Homogeneous rubber is attached to a metal disk, only one piece is needed–the best available piston cup.
