  • E5 Profile, Premium Rounded Lip U-cup Rod Seal

    The E5 profile is a non-symmetrical rod seal designed to seal both lubricated and non-lubricated air. To ensure that critical surfaces retain lubrication, the radius edge of the lip is designed to hydroplane over pre-lubricated surfaces. The standard compound for the E5 profile is Parkers proprietary Nitroxile ELF compound N4274A85. This compound is formulated with proprietary internal lubricants to provide Extreme Low Friction and excellent wear resistance. This compound provides extended cycle life over standard nitrile and carboxylated nitrile compounds.

  • TR Profile (Rod T-seal) Compact Seal with Anti-Extrusion Technology

    Parkers rod T-seal is designed to retrofit o-rings in no back-up, single back-up and two back-up standard industrial reciprocating glands. Its compact design provides improved stability and extrusion resistance in dynamic fluid sealing applications. The flange or base of the T-seal forms a tight seal in the gland and supports the anti-extrusion backup rings. When energized, the back-up rings bridge the extrusion gap to protect the rubber sealing element from extrusion and system contamination. The rod T-seal eliminates the spiral or twisting failure that can occur when o-rings are used against a dynamic surface. Parker offers the rod T-seal in a variety of elastomer and back-up ring compounds to cover a wide range of fluid compatibility, pressure and temperature requirements.

    Profile TR0 for no back-up o-ring gland (standard offering)

    Profile TRS for single back-up o-ring gland

    Profile TRT for two back-up o-ring gland

    The TR profile is sold only as an assembly (elastomer and back-ups).

  • OC Profile, Compact PTFE Rod Cap Seal

    The Parker OC profile is a bi-directional rod seal for use in pneumatic and low to medium duty hydraulic systems. The OC profile is a two piece design utilizing a rectangular PTFE cap and standard size Parker o-ring. The OC profile is an excellent choice for applications requiring a compact design. The unique properties of the modified PTFE provide added wear resistance for improved cycle life. Parkers OC profile will retrofit non-Parker seals of similar design. The OC profile may be ordered without the energizer by omitting the energizer code. See part number nomenclature.

    Notched side walls: Notches can be added to the side walls of the PTFE cap. This can help to optimize the seals response to fluid pressure. Notched side walls help ensure that fluid pressure fills the cavity between the side face of the seal and the side face of the seal gland. Consult Industrial Seal Inc. for the availability and cost to add side notches to the OC profile.

  • CR Profile, PTFE Rod Cap Seal to Retrofit O-ring Glands

    The Parker CR profile is a cap seal with anti-extrusion, low friction and low wear features. The seal is a bidirectional rod seal for use in pneumatic and low to medium duty applications. Because of its short assembly length, it requires minimal space in the rod housing. The three CR profiles will fit into standard o-ring grooves without modification. Parkers CR profiles will retrofit non-Parker seals of similar design.

    CR0 fits a standard o-ring groove
    CR1 fits an o-ring groove designed for one back-up ring
    CR2 fits an o-ring groove designed for two back-up rings

    The CR profile may be ordered without the energizer by omitting the energizer code. See part number nomenclature.

  • V6 Profile, Cushion Seal

    The V6 profile provides a check valve type action for use in cushioning pneumatic cylinders. The V6 profile seals against the cushioning piston or spud, allowing pneumatic pressure to build and cushion the cylinders end stroke. Through a series of slots and pedestals the intake flow is then able to easily blow past the cushion seal to fill the cylinder. The installation of the cushion seal is very simple as it manually snaps into the groove recess. The V6 profile is available in proprietary Parker compounds formulated for low friction, extrusion resistance, and high temperature. The V6 profile can be used in a wide variety of NFPA cylinders and will provide excellent performance and long life.

  • OR Profile, Rotary PTFE Cap Seal

    The Parker OR profile is a bi-directional rod seal for use in pneumatic and low to medium duty rotary or oscillating applications. The OR profile is a two piece design comprised of a standard size o-ring energizing a wear resistant PTFE cap. The OR profile offers long wear and low friction without stick-slip. This PTFE outer diameter is designed with a special interference with the o-ring to eliminate spinning between the o-ring and seal. Special grooves are designed into the PTFE inner diameter to provide lubrication and create a labyrinth effect for reduced leakage. The seal is commonly used in swivel joints, hose reels, and machine applications. Parkers OR profile will retrofit non-Parker seals of similar design. The OR profile may be ordered without the energizer by omitting the energizer code. See part number nomenclature.
