The Hallite 621 is a top of the range high pressure rod seal. The design of the seal incorporates a unique profiled NBR energiser to ensure complete lip actuation under all pressure conditions and to cushion the seal against shock loadings.

The shell is moulded in Hallite’s Hallite’s high performance polyurethane Hythane® 181, ensuring flexibility for installation and performance at low temperatures.

The Hallite 621 also benefits from Hallite’s twin lip profile for dry rod sealing.
