● While most of the DLSEALS Spring Energized PTFE seals canbe used as static radial seals, the DLSEALS 103 is generallyrecommended for this service.lt’s moderate to high spring load provides positive sealing under most staticsealing conditions.

● The most common applications of DLSEALS Seals arereciprocating radial motion.For rod piston sealingand similar applications,the DLSEALS Seals 400 isrecommended for general purpose sealing at lowto moderate pressures.This series has a low load, high deflection spring that provides low friction sealing and long wear life, and compensates for minor hardware misalignment.The DLSEALS Seals APS uses a round wire spring energizer,which has the advantage of producing an almost constantspring load over a wide deflection range.This type of sealaccommodates variation in hardware dimensions (tolerances)and/or provides effective sealing loads over.

large seal wear allowance,Also it can be installed in verysmall coil, which makes it particularly suitable for smallseals and seals requiring low friction values. For more severe dynamic conditions,the DLSEALS Seals 103isrecommended.The higher spring load provides positives sealing with some increase in seal friction. articularly suitable for medium to high pressure service,the 103 is also an excellent rod seal for positive sealing. The DLSEALS Seals 400 comes with durable spring and ruggedjacket,is an excellent choice for heavy-duty sealing applications and long wear life.
