The secondary sealing lip located behind the primary sealing lip improves stability of the seal in the gland. The unique profile of the NBR energizer ensures the primary sealing lips maintain contact under low or no pressure situations while ensuring proper sealing at higher pressures.
The Hallite 621 also incorporates an acetyl anti-extrusion ring to withstand side loads and extreme pressure peaks even with the extrusion gaps.
The PA 533 material is heat stabilised 33% glass reinforced nylon 66, which offers excellent bearing properties.
Compatible with hydraulic and lubricating oils. The PA 533 material is not recommended for use in water based fluids (HFA) or where significant water is present, due to the swell of the nylon.
