E4 U-Cup

E4 (Piston Seals)

Profile E4 NBR Piston Seal is a lip seal specially developed for use in pneumatics. Profile E4 is fully interchangeable with the profile C2 standard series formerly used in pneumatics.

Application:

• Working Pressure: = 16 bar

• Working Temperature: -30°C to 80°C (-22°F to 176°F)

• Surface Speed: = 1 m/s

Advantages:

• Sealing lip geometry designed to operate with lubricated air as well as dry and oil-free air.

• Robust design based on favorable dimensions of seal cross-section.

• Tight fit into the groove ensures reliable operation.

• Optimal friction characteristics after careful initial lubrication obtained by sealing lip geometry retaining lubrication film.

• Suitable for cylinders with cushioning.

• Extended service life due to the use of proven elastomers.

• Easy snap assembly in grooves of simple design.

• Special seal geometry ensures optimal function with flow-controlled exhaust air.
