Flange Seals
Flange seals provide the front-face static sealing function within flange connections. There are two major design principles available, either for internal or external pressure. Various designs in a broad range of compounds provide individual features. Parker’s flange seals offer enhanced sealing performance from pressure-free to high-pressure conditions. Designs can be optimized to be insensitive to pressure peaks, show high extrusion resistance or media resistance.

HIGH PRESSURE OIL SEALS
0 out of 5(0)The rotary shaft oil seal is an indispensable component in lubricated rotating equipment and must be chosen with caution in order to ensure that the correct design and materials are used to provide a long-lasting life for the rotating equipment.
These variations of the G and M type seals are engineered to withstand pressure up to 10 BAR (1 MPa), although this limit has been exceeded in some applications. These seals are available with or without an additional dust lip. The G type and its high pressure variants show a metal insert covered by rubber, while the M type and its variants offer a bare metal body on the outside diameter.

Fastener Seals
0 out of 5(0)Parker´s fastener seals are composite sealing washers, consisting of a metallic carrier and a vulcanized elastomer sealing lip. They provide a static sealing function on flanges or threaded connections, and consistently assure ideal compression conditions between the housing components to prevent the destruction of the sealing lip. Parker´s fastener seals provide long and reliable service, a high degree of reusability, and easy assembly. They have been engineered to eliminate over-compression, provide easy and accurate placement of the seal thanks to a self-centring design, and deliver improved joint stability via the solid metal-to-metal contact.

V-RINGS
0 out of 5(0)Endless all-rubber face seal produced up to 2.100 mm in one single piece and joint-vulcanized for larger diameters. It works as a front seal and it is the perfect solution to prevent contamination from dirt, dust, or water. It can be used as a secondary seal to protect the primary seals.
The V-Ring is a seal of easy use and assembly since it is self-retaining on the shaft and does not need a special finishing grade and tolerance. The contact area can have a roughness from Ra 0.5 to Ra 1.6 according to the speed and the fluids to be sealed.

Buffer Seals
0 out of 5(0)Buffer seals are primary seals in tandem sealing configurations. Designed to withstand pressure peaks from the system, Parker hydraulic buffer seals employ an unsymmetrical cross-section design and are often combined with anti-extrusion rings to prevent gap extrusion. State-of-the-art designs include a pressure-relief functionality from the low pressure side, addressing concerns related to drag-oil pressure trapped between the tandem elements. Our comprehensive selection of premium buffer seals are designed for use with hydraulic cylinders, providing excellent wear resistance, and high pressure capabilities. Parker buffer seals combine advanced polymer materials, such as PTFE or TPU with sophisticated product design.
