The 133 Series is a heavy-duty polyurethane seal with multiple features that include a double-lipped U-Cup design, an internal O-ring energizer and a reinforced backup ring on the heel. This seal is ideal for pressure spikes and large extrusion gaps common in mining applications.
Symmetrical design for optimal sealing performance
Internal O-Ring works more efficiently at varying pressures
Double-lip design increases efficiency and performance
Highly extrusion resistant in large gap conditions
Easy to install
The 133 Series rod seal is typically used in heavy-duty applications, where pressure spikes and large extrusion gaps exist.
Typical applications include:
The 133 Series rod seal features high-grade polyurethane. Standard materials are MP03 H-PU, NBR O-ring and polyacetal backup ring. To suit a variety of applications, the series is also available in NBR, H-NBR, EPDM and high temperature-resistant FPM.
