The Lycotek Seals line spans ten specialized categories — hydraulic and pneumatic rod and piston seals, wiper seals, spring-energized PTFE compounds, rotary shaft seals, O-rings, wear rings, piston rings, PTFE cup seals, and mechanical face seals.
Each family is engineered around a specific motion type and operating envelope, from standard ISO-groove hydraulics to metal-spring seals rated for vacuum and aggressive media. Use the overview below to find the right category for your application.
►PTFE Rod Seals
Single- and double-acting rod seals for hydraulic and pneumatic cylinders.
Up to 60 MPa · 15 m/s · Ø 2–3,300 mm · −70 to +300 °C
►PTFE Piston Seals
Double-acting piston seals engineered for high cycling rates and low friction.
Groove-compatible with ISO 7425 standards
►PTFE Wiper Seals
First line of defense against dust, moisture, and contamination on the rod side.
Sealed and unsealed profiles available
►PTFE Spring Energized Seals
Metal-spring energized PTFE seals for extreme temperature, vacuum, and aggressive media.
No elastomer · −200 to +325 °C · suited to chemical, pharma, and food
►PTFE Rotary Shaft Seals
For rotating and oscillating shafts in slow-to-medium speed applications.
Up to 2 m/s · pressure-tight · replaces conventional lip seals
►PTFE Cup Seals
For reciprocating pistons and rods in pneumatic and low-pressure hydraulic systems.
< 20 bar · 15 m/s · self-energizing PTFE memory
►Piston Rings
For reciprocating pistons in hydraulic, pneumatic and compressor cylinders.
PTFE · PEEK · carbon-graphite · bronze · cast iron · solid and split designs
►O-Rings
Standard and custom O-rings in NBR, FKM, EPDM, HNBR, silicone, and PTFE.
Inch and metric sizes · AS568 / DIN 3771 dash sizes
►Wear Rings
Guide rings and strips that support lateral loads and protect against metal-to-metal contact.
Extended cylinder life, reduced wear on piston and bore
►Mechanical Face Seals
Heavy-duty rotary seals for mining, construction, and steel plant equipment.
Replaceable sealing faces · high-pressure rotating service
►Molded Rubber Seals
Custom-molded elastomer parts for sealing, damping and bonding.
Compounds to match every media and temperature.
