Descripción completa del producto

The PARK-O-PAK® rod seal TA made of wear-resistant Ultrathan® is a compact seal design for hydraulic applications. Due to its symmetric design, the seal can also be used as a piston seal.
The O-ring guarantees the pre-loading of the seal lips, even under low pressures or vacuum. Due to the good setting behavior of the elastomer O-ring, this pre-loading is largely constant. As system pressure increases, compression of the sealing edges rises due to the pressure-dependent deformation of the seal profile.

There are three variants of the PARK-O-PAK® product series. The product series BA is suitable for standard grooves, e.g. according to ISO 5597. The product series SA is suitable for axially short compact designs. The product series TA is suitable for radially slim designs, e.g. for telescopic cylinders.

• Robust seal profile for harshest operating conditions.
• Extreme wear resistance.
• Easier installation.
• Insensitive to pressure peaks.
• High extrusion resistance.
• Excellent media resistance in case of suitable compound selection.
• Suitable compounds available for special requirements of the chemical process industry.
• Suitable compounds available for special requirements of the food processing industry.
• Installation in closed and undercut housings.
• Low compression set.
• Further dimensions of machined series with short lead times available.

Range of application:
Mainly for the sealing of piston rods and plungers in heavy duty applications in mobile and stationary hydraulics.

The TA rod seal is available in the following compounds:
00030 - Industrial applications
00020 - Light-duty
00043 - Low temperatures
00064 - Heavy-duty
