The Hallite 716SPN is a single-acting, o-ring energized rod seal proven to be ideal for a variety of applications. This seal is typically made out of our high-quality Hythane® materials combined with an elastomer energizer design optimized for superior performance.
The Hallite 716SPN can be used as a single rod seal or incorporated into a rod sealing system as the secondary seal. The 716SPN is paired with an R16 made from an Armorlene® PTFE material which becomes the primary seal in the system (see drawing above) with the 716SPN as the secondary seal in the system. This tandem arrangement is ideal for long- stroke and high-speed applications, providing optimum sealing performance.
This design fits standard ISO 7425-2 grooves and is offered in a wide range of metric and inch options.
