Short Lip PTFE Seal

• Wiper lip design
• Reciprocating service
• Low friction seal material
• Canted coil spring energized
• Housing-mounted

The short lip PTFE seal consists of a U-shaped seal jacket with an asymmetrical wiper lip design. It is energized with a canted coil spring made from corrosion-resistant 316 stainless steel. The spring helps accommodate for small changes in the seal lip caused by wear, temperature change, or tolerance variations in the assembly. It also ensures effective sealing at startup and low pressures. Grooves in the seal jacket act as multiple scrapers to reduce media migration. This radial seal is best suited for housing-mounted applications and reciprocating service.
