Seals

Back-up Rings

Back-up Rings

Back-up rings are the most common anti-extrusion devices employed in dynamic and static sealing, designed to prevent the migration of sealing material into the extrusion gap under the system pressure. Parker offers a wide range of back-up ring geometries and materials to suit every seal type and application. They are open or closed shapes for snap assembly made of a broad range of compounds which are highly resistant to thermal or mechanical stress. Parker back-up rings help reduce costly downtime and ensure long-term functional reliability.

Buffer Seals

Buffer Seals

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.

Cushioning Seals

Cushioning Seals

In pneumatic cylinders, cushioning seals are part of a design that provides for controlled final position retardation. Up on approaching the final position, a tapered sleeve, firmly located on the piston rod, progressively closes off the open passage toward the line connection of the cylinder. In this phase of motion, the defluent medium is led via a, usually adjustable, needle valve, the adjustment of which controls the degree of stroke movement retardation. During reverse operation, the cushioning seal designs provide a non-return valve functionality and ensure free flow. Parker offers robust seal profiles, suitable for the harshest operating conditions and showing extreme wear and high-temperature resistance.

Custom Seals

Custom Seals

Parker has the skills and experience to offer custom seals that are completely unique and designed exclusively for a specific application profile. Parker’s application engineers are on hand to ensure you get the best solution for your application needs, whether those be functional requirements, gland limitations, installation improvements, etc. Our advanced material know-how and design expertise is at your fingertips whenever you require a bespoke sealing solution.

Fastener Seals

Fastener Seals

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.

Flange Seals

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.

Guiding Elements and Wear Strips

Guiding Elements and Wear Strips

Parker’s selection of guiding elements and wear strips includes U-cup, press-in-place extremely wear-resistant rod, seal, and wiper and guidance systems for pneumatic cylinders; rod guide rings for hydraulic-cylinder and comparable lubricated applications; and countless other offerings.

HIGH PRESSURE OIL SEALS

HIGH PRESSURE OIL SEALS

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.

V-RINGS

V-RINGS

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.

WIPER SEALS

WIPER SEALS

Rod wipers for alternative linear movements have been designed to give first-class protection to seals and driving bodies in hydraulic and pneumatic cylinder applications.

The main function of the rod wiper is to keep the rod clean from any possible impurity.

The •FP• rod wipers have a chamfer on the outside diameter to facilitate the press fitting into the housing. To simplify the installation, the bore should have a chamfer as per DIN 3760.
