DESCRIPTION

The RB-621 is the Hallite 621 and is a top of the range high pressure rod seal. The design of the seal incorporates a unique profiled NBR energizer to ensure complete lip actuation under all pressure conditions and to cushion the seal against shock loadings. This seal also incorporates a polyacetal anti-extrusion ring.

The shell is molded in Hallite’s high performance polyurethane Hythane 181, ensuring flexibility for installation and performance at low temperatures. This seal also benefits from Hallite's twin lip profile for dry rod sealing.
