Parker Rod Seals
Parker offers a wide range of hydraulic and pneumatic rod seal proﬁles to meet the broad demands of the ﬂuid power industry. These rod seals are offered in a variety of compounds and lip geometries for the best possible solution for a given application. A majority of Parker rod seals are manufactured utilizing a precision knife trim process to ensure the sealing contact with the dynamic surface yields the best possible performance. When combined with other Parker proﬁles, including bearings, buffer seals, dirt excluders, and static gland seals, Parker rod seals have proven to provide long life and leak free performance.
BD Proﬁle, Premium O-ring Energized Lip Seal
The BD proﬁle is a non-symmetrical proﬁle rod seal. Its rectangular shaped cross section ensures stability in the gland. The o-ring energizer functions as a spring to maintain sealing contact under low pressure or vacuum applications.
BT Proﬁle, Premium U-Cup Rod Seal with Secondary Stabilizing Lip
The BT proﬁle is a non-symmetrical design for use in hydraulic rod sealing applications. Using Finite Element Analysis, the BT proﬁle was designed to provide improved sealing performance and stability in the gland. A knife trimming process is used to form the beveled lip which is best for removing ﬂuid from the rod.
BS Proﬁle, Premium U-Cup Rod Seal with Secondary Stabilizing Lip
The BS proﬁle is a non-symmetrical proﬁle designed for use in hydraulic rod sealing applications. A knife trimmed beveled sealing lip does an excellent job wiping ﬂuid from the rod. In addition, a secondary sealing lip is located just above the base of the seal to provide enhanced sealing performance and ensure a tight, stable ﬁt in the gland.
B3 Proﬁle, U-Cup Rod Seal
The B3 proﬁle is a non-symmetrical design for use in hydraulic rod sealing applications. The diameter of the B3 proﬁle is designed to ensure a tight static side seal when installed. The knife trimmed, beveled lip does an excellent job wiping ﬂuid ﬁlm. The B3 proﬁle is available in Parker proprietary compounds offering extrusion resistance, long wear, and low compression set.
UR Proﬁle, Industrial U-Cup Rod Seal
The UR proﬁle is a non-symmetrical, hydraulic cylinder rod seal. The knife trimmed, beveled lip faces the rod to provide enhanced low to high pressure sealing and wiping action. The UR proﬁle is an economical choice, available in Parker’s wear and extrusion resistant Molythane compound.
E5 Proﬁle, Premium Rounded Lip U-Cup Rod Seal
Parker’s 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 Parker’s proprietary Nitroxile® extreme low friction (“ELF”) compound N4274A85.
TR Profile (Rod T-seal) Compact Seal with Anti-Extrusion Tecnology
Parker’s 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 back-up rings.
ON Profile, PTFE Rod Cap Seal
The Parker ON proﬁle is a bi-directional PTFE rod seal for use in low to medium duty hydraulic systems. The ON proﬁle is a simple two piece design comprised of a standard size Parker o-ring energizing a wear resistant PTFE cap. The ON proﬁle offers long wear and low friction, and because of its short assembly length, requires minimal space in the rod housing.
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 bi-directional 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.
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.
BR Profile, Premium Buffer Seal
The BR proﬁle is a compact rod seal designed to act as a buffer seal for the primary rod seal. As a buffer seal, the BR proﬁle provides the majority of the rod sealing performance while allowing ﬂuid to by pass onto and energize the primary rod seal. Fluid located between the BR proﬁle and the rod seal will relieve back into the cylinder by ﬂowing past the BR proﬁle’s ﬂexible static side lip and slotted pedestals.
OD Profile, PTFE Buffer Seal
The Parker OD proﬁle is a rod seal that can be used as a buffer seal in conjunction with a primary rod seal or in tandem with itself to form a sealing system for higher performance. The OD proﬁle is a uni-directional seal, with a unique design that allows trapped ﬂuid pressure back into the cylinder. When the rod extends from the cylinder the OD proﬁle is riding on a sealing point, creating a high compression point to limit leakage.
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 cylinder’s 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.
OR Profile, Rottary 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.
