Single acting U-Section AU rod seal with POM anti-extrusion rings.

Design 

Claron style HBI is a single acting seal for gland applications using the same housing designs as Style CS6. The sealing element is manufactured in Polyurethane, with an Acetal anti-extrusion ring. Designed as a high pressure, low friction seal for use in second generation tandem sealing arrangements. The HBI seal is used on the pressure side, and a 'low leak' but higher friction seal on the non-pressure side to collect the oil film during the positive stroke. This type of arrangement is used where both low friction and low leakage are required. The seals high pressure resistance makes it suitable for use in heavy duty applications where shock loads and pressure spikes occur, as found in mobile plant equipment.
