Universal

The O-ring is considered a universal sealing device. Used as static, dynamic, radial or face seals. A wide range of elastomers is available.

Parbak™ Back-Up Rings

Dynamic

For use as an anti-extrusion device in dynamic O-ring applications where there is high pressure or excessive gland clearance.

Molded Shapes

Universal

Custom molded elastomer seals and shapes for special applications.

Drive Belts

Dynamic

O-ring drive belts for critical applications are available in a wide range of materials from polyurethane to ethylene propylene.

Sheet Stock

Static

Elastomer sheets in various sizes and thicknesses for use as die-cut gaskets and in special applications.

PTFE Piston Rings

Dynamic

Parker offers a complete range of both activated and non-activated PTFE piston seals and rings for hydraulic and pneumatic applications.

PTFE Rod Seals

Dynamic

Parker offers a complete range of both activated and non-activated PTFE rod seals for hydraulic and pneumatic applications.

PTFE FlexiSeals™

Dynamic

FlexiSeals are PTFE sealing devices energized by special metal springs to maintain lip contact during no or low pressure service.

PTFE Fluid Power Seals™

Dynamic

Fluid Power Seals are special PTFE seals designed for use as either piston or rod seals and are activated by an elastomer O-ring.

PTFE Lip Seals

Rotary

Lip Seals are for use in rotary applications up to 150 psi in corrosive and abrasive environments. Low friction, wide temperature range.

Custom PTFE Seals

Dynamic

Custom designed PTFE seals for unique applications. May be single or double sealing with metallic or elastomer actuators.

PTFE Canned Lip Seals

Rotary

Metal cased lip seals offer the same advantages as all other PTFE seals, with the added ability to be press-fit into an outboard groove.

PFA FlexiTube™

Static

PFA encapsulated spring for special static applications.

PTFE Components

Universal

PTFE components such as skived tapes, valve seats, loaded bearings and other special molded or machined PTFE shapes.

Type D Wipers

Dynamic

Snap-in wiper designed to scrape outside contaminants off cylinder rods in medium to heavy-duty hydraulic cylinders.

SHD Wipers™

Dynamic

1

AK Wipers™

Dynamic

Snap-in wiper fits into Type D Wiper grooves. Has additional lip on O.D. to prevent contaminants from bypassing O.D. of wiper.

Canned Wipers

Dynamic

Press-in wiper used in heavy-duty mobile hydraulic equipment.

PZ Profile™

Dynamic

Light-duty double-acting pneumatic piston seal.

AN6226 Series U-Cups

Dynamic

Government standard. Has larger cross-section than 8400/8500 series. Thin lips offer low friction. For use in low-pressure applications.

8400/8500 U-Cups™

Dynamic

Light-duty hydraulic and pneumatic U-cups used in pneumatic cylinders for industrial and low-pressure applications.

BS U-Cups™

Dynamic

Medium-duty hydraulic cylinder applications below 5000 psi. Recommended for mobile construction and industrial equipment.

BT U-Cups™

Dynamic

For heavy-duty hydraulic cylinders. Less weepage than BS design. Should be used with buffer rings as a sealing "system".

Wear Bands

Dynamic

Glass loaded nylon rings to prevent metal-to-metal contact in all types of hydraulic cylinder applications.

Modular Back-Ups

Dynamic

Non-positive actuated anti-extrusion devices for use down stream from single and double-acting rod or piston seals. Up to 10000 psi.

Standard PolyPaks™

Dynamic

Light-duty hydraulic piston and rod seals recommended where strokes are short and system pressures below 3000 psi.

Type B PolyPaks™

Dynamic

Heavy-duty rod seals for mobile and heavy duty industrial equipment.

Deep PolyPaks™

Dynamic

Piston and rod seals for medium to heavy-duty hydraulic cylinders.

Type BD PolyPaks™

Dynamic

Type B geometry with added secondary lip for increased sealability for use in medium to heavy duty mobile and construction equipment.

OK Piston Rings™

Dynamic

Compact double-acting piston seal used on medium and heavy-duty construction equipment.

PSP Seals™

Dynamic

Medium-duty double-acting piston seal used in industrial and agricultural equipment.

PIP Seals™

Dynamic

Double-acting Type B PolyPak/PIP Ring assembly for use as piston seal in medium-duty industrial cylinder applications.

Piston Cups

Dynamic

Single-acting piston seals for use in older type industrial hydraulic cylinders.

T-Seals

Dynamic

Piston and rod seals used in pneumatic and hydraulic applications in industrial cylinders.

SCL Seals™

Dynamic

Single-acting rod seals with conventional elastomer cap on an elastoplastic base used on industrial and construction equipment.

Vee-Packing

Dynamic

Adjustable packing used in telescoping cylinders and many types of older hydraulic equipment. Multiple sealing lips.

Cushion Seals

Dynamic

Pneumatic dampening devices to slow travel and absorb kinetic energy in pneumatic cylinders.

Bumper Seals

Dynamic

Piston seal and bumper in a single unit. Used on pistons of pneumatic activators to seal and absorb kinetic energy.

Buffer Rings

Dynamic

Primary rod seal when used in sealing system in combination with BT U-cup. For use in heavy-duty industrial and mobile equipment.

Static Face Seals

Static

Made from a wide range of sealing grade elastomers, these extruded and cut static face seals are available from .030" through 2.50" O.D.

Custom Extruded Profiles

Universal
