`Symmetrical PolyPak® Seal Profiles
`for Rod or Piston Applications
`
`PolyPak® Sealing
`
`Parker’s PolyPak® seal is a patented precision molded multi-purpose
`seal. The Parker PolyPak combines an o-ring type synthetic rubber
`o-spring with a conventional lip-type seal to produce a unique sealing
`device capable of sealing both vacuum, high and low pressure.
`
`Conventional lip seals, such as the standard u-cups are prone to
`leakage under low pressure because little or no lip loading is inherent in
`the basic seal design. The Parker PolyPak however, is a squeeze type
`seal and provides high sealability at low pressure. As system pressure
`increases, additional force is applied to the PolyPak’s seal interface and
`as pressure continues to increase, lip loading is automatically increased
`to compensate for this higher pressure and thus maintain a positive,
`leak-free seal from hard vacuum to over 60,000 psi with proper design
`and auxiliary devices.
`
`NOTE: Standard, Deep and Type
`B PolyPak Gland Dimension Table
`(Table 8, page 10) is provided as

`

`PolyPak Sealing
`
`In addition to providing superior sealing in vacuum,
`low and high pressure applications, the PolyPak
`seal offers a number of distinct advantages over
`conventional symmetrical or non-symmetrical u-cup
`seals including:
`• The PolyPak’s o-spring stabilizes the seal under
`extreme pressures, preventing seal lip distortion
`and rolling or twisting in the gland.
`• At low or high temperature extremes, the o-spring
`maintains lip loading on both I.D. and O.D. of the
`seal interface.
`• The PolyPak seal can be stretched or squeezed to
`accommodate oversize cylinder bores and un-
`dersize rods. As long as the seal cross-section is
`correct in relation to the radial groove dimensions,
`the PolyPak will compensate and maintain proper
`lip loading.
`• The range of materials available to the user of the
`PolyPak seal insures the proper combination for
`abrasion, extrusion, temperature resistance and
`fluid compatability which produces high sealability
`and long life.
`
`PolyPak seals are available in three styles:
`1. Standard PolyPak (SPP Profile)
`2. Deep PolyPak (DPP Profile)
`3. Type B PolyPak (BPP Profile)
`
`Rod Sealing with PolyPak Seals
`As a general rule, rod seals are more critical in
`nature than their companion piston seals. With
`increasing OEM requirements for “dry rod” capability,
`both to conserve system fluid and avoid leakage,
`the design and selection of the rod seal can be more
`challenging than its piston counterpart.
`
`Parker recommends the use of the Type B PolyPak
`(BPP Profile) for rod seal applications due to its design
`features, including:
`• Excellent film-breaking capability of the beveled lip
`design
`• The higher level of lip loading provided by the Type
`B offers maximum sealability
`• The long body of the design provides maximum
`stability
`
`Piston Sealing with PolyPak Seals
`Piston seals can be classified in two categories:
`single-acting and double-acting. The single acting
`seal is only required to seal in a single direction as
`system pressure is seen on only one end of the
`piston (return of the piston in a single-acting system
`is accomplished either by gravity or spring loading).
`The double-acting cylinder requires that the piston be
`sealed in both directions of stroke as system fluid is
`applied to one side or the other to achieve movement.
`
`Please see the individual PolyPak profile pages for
`explanation and differentiation on selecting PolyPak
`profiles for piston applications.
`
`PolyPak Material Combinations
`PolyPak seals can be configured in numerous
`o-spring energizer and shell combinations. Table 2
`represents “standard” combinations. Care should
`be taken to insure that both the PolyPak shell and its
`companion o-spring energizer are compatible with the
`system temperature, pressure, and fluid requirements.

`SPP Profile, Standard PolyPak
`
`SPP Profile, Standard PolyPak,
`Square Cross-Section O-ring Energized Lip Seal
`
`Parker’s Standard PolyPak is a squeeze seal with a symmetrical profile
`for use in either rod or piston applications. The standard Molythane shell
`provides high wear resistance and the o-ring energizer functions as a
`spring to maintain sealing contact under low pressure. The Standard
`PolyPak utilizes a scraper lip design formed by a precision trimming
`process. The scraper edge wipes both fluid film and contamination
`away from the seal. A wide selection of sizes and alternate compounds
`allow this profile to match up with many hydraulic applications. The
`Standard PolyPak is an economical choice as a stand alone rod or
`piston seal. With less squeeze force than the Deep or Type B profiles,
`the Standard PolyPak can be installed back to back, in separate glands,
`for bi-directional sealing. To protect against pressure trapping, it is
`recommended that the o-ring be removed from the Standard PolyPak
`facing the lower pressure side of the application.

`
`BPP Profile, Type B PolyPak
`O-ring Energized Lip Seal with Beveled Lip Design
`
`Parker’s Type B PolyPak is a squeeze seal with a symmetrical profile
`for use in either rod or piston applications. The rectangular shape of its
`cross section ensures stability in the gland. The standard Molythane
`shell provides high wear resistance and the o-ring energizer functions
`as a spring to maintain sealing contact under low pressure or vacuum
`applications. The beveled lip design of the Type B PolyPak is excellent
`for cutting fluid film. The sharp beveled lip is formed by a precision knife
`trimming process. A wide selection of sizes and alternate compounds
`allow this profile to match up with many hydraulic applications. The Type
`B PolyPak is an economical choice as a stand-alone seal or can be used
`in tandem with a buffer seal. In piston applications, this seal will function
`as a unidirectional seal. Instead, for bi-directional piston sealing,
`incorporate a PIP ring (see Section 7, Catalog EPS5370). Type B
`PolyPaks should not be installed back to back, in bi-directional pressure
`applications, as a pressure trap between the seals may occur.
