DESIGN
The Hallite 621 is a top-of-the-range twin lip rod seal designed to provide a dry
sealing solution in heavy-duty applications.
The secondary sealing lip located behind the primary sealing lip improves stability
of the seal in the gland. The unique profile of the NBR energiser ensures the
precision trimmed primary sealing lips maintain contact under low or no pressure
situations while ensuring proper sealing at higher pressures. This unique profile is
also used in the Hallite 622 twin lip rod seal. The Hallite 621 also incorporates an
acetal anti-extrusion ring to withstand side loads and extreme pressure peaks even
with the extrusion gaps, which are the result of using remote plastic bearing strips
like the Hallite 506 or 708.
The Hallite 621’s seal shell is molded in Hythane® 181, Hallite’s high-performance
polyurethane, for easy installation and excellent low temperature performance.
