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.
