716SPN ROD SEAL
4Pages

TECHNICAL DETAILS 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. • Long wear and high extrusion resistance F E A T U R E S • Design minimizes occurrence of stick-slip • Excellent performance as a single or tandem seal system • Design offers excellent dynamic and static sealing properties Part Number Structure 716MR00500N111_ M UNIT OF MEASUREMENT M = Metric E = Inch Refer to Installation Recommendations and use designator for desired application Metric = mm X 10 Inch = inches X 1000 N ENERGIZER MATERIAL Refer to Energizer Table for desired energizer material SPECIAL FEATURE Refer to Material Table for desired (face) material
