T683 ROD SEAL Single Lip
2Pages

DESIGN The Hallite 683 is an asymmetric, single lip U-ring rod seal designed to provide a dry sealing solution in light and medium-duty applications. The heel of the seal is angled, with support ribs to reduce shaft contact and provide pressure relief, allowing pairing with double lipped wipers. The ribs help in reducing friction by supporting localised lubrication and thus reduce localised temperature at the sealing lips, contributing to longer seal life. The seal is a single lip modification of the well-established Hallite 605 profile and is ideal for applications that require a double-lipped wiper, such as the Hallite 839, Hallite 844, Hallite 846, or Hallite 864. The Hallite 683 is also offered in other high quality Hythane® materials to best fit the needs of the application. • Excellent wear resistance • Prevents pressure build up between seal and double-lipped wiper • Performs well over wide temperature range and is extremely effective in low temperatures • Robust design MATERIALS This product comes in a number of material options to extend operating conditions.

Maximum Speed Temperature Range Maximum Pressure Maximum Pressure with Backup Ring Data given are maximum values and can apply depending on specific application. Maximum ratings of temperature, pressure, or operating speeds are dependent on fluid medium, surface, gap value, and other variables such as dynamic or static service. Maximum values are not intended for use together at the same time, e.g. max temperature and max pressure. Please contact your Hallite technical representative for application support. OPERATING CONDITIONS Pressure Rating: Can be extended with use of backup ring. Seek...
