The PTFE Lip Seal Design Guide is your premier PTFE seal selection guide for hardware design, seal configuration and material specification options for a wide range of standard and complex applications. FlexiSeal The FlexiSeal is a spring-energized U-cup utilizing a variety of jacket profiles, spring types and materials in Rod & Piston, Face

The O-Ring Loaded U-Cup is a unique design that combines a precision molded "U" configuration packing with an elastomer loader. This seal was originally designed to improve the low pressure sealing capabilities of a standard lip type packing but the design principle has been effective in dealing with high and low temperature

In fact, this PTFE Lip Seal Design Guide exists separately from other Parker EPS market-specific publications precisely because virtually every industry has specific needs for the unique physical and chemical properties of these remarkable seals.

Type B PolyPak. A rectangular shaped symmetrical squeeze seal with a knife trimmed beveled lip. Standard materials include 4615, 4622, 4651, 4263, 4207, 4266. 6-10 5. A dual lip seal created by the combination of a standard PolyPak square shell and a rubber lip seal/energizer. Standard materials are a 4615 shell and 4180 lip seal/energizer.

This design manual is intended as a guide. elastomeric lip seals . ing out the sealing lips, creating a tight seal against the groove.

Sealing lip design. The form and design of a sealing lip is based on knowledge gained through research and development activities as well as wide practical experience obtained by SKF in

The typical geometry for a radial lip seal, commonly known as an oil ring, is shown in Fig. 14.16 These seals are used to retain lubricants and exclude dirt, and are well suited to moderate-speed and low-pressure applications. The use of a radial lip seal for a bearing is illustrated in Fig. 14.17.

Nitrile Buna-N 70 durometer compound is the standard material for our seals and is recommended for a majority of common applications. Nitrile lip seals work
