LC-Profile-Seal

LC Profile Seal

Parker’s LC Profile Seal offers several advantages over more traditional two-piece seal geometry. The problem with traditional two-piece seals occurs at installation and in service, during rapid fluctuations in pressure where expander rings can become partially dislodged – resulting in leakage. The LC Seal’s unique one-piece construction eliminates problems associated with seals containing rubber expander rings used to load the seal lips to maintain leak-free operation.

Product Highlights:

  • Better Compression Force
  • Fits Standard Groove Dimensions
  • Computer Aided Testing

Advantages of a One-Piece Seal

Parker’s LC Profile Seal offers several advantages over more traditional two-piece seal geometry. The problem with traditional two-piece seals occurs at installation and in service, during rapid fluctuations in pressure where expander rings can become partially dislodged – resulting in leakage. The LC Seal’s unique one-piece construction eliminates problems associated with seals containing rubber expander rings used to load the seal lips to maintain leak-free operation.

Better Compression Force

Notice that the LC Profile has a ‘back beveled’ lip. This supports the sealing lip from both sides causing the compressive force to be directed to a narrower sealing line. Other seals have lips that roll toward the unsup- ported side when installed resulting in lower compres- sive force, distributed over a wider sealing line (See Figure 1). Design enhancements in the LC Profile geometry concentrate compressive force to reduce leakage and improve overall sealability.

Fits Standard Groove Dimensions 

Fluid Power Seals--Parker Fluid Power, Rotary & PTFE Seals--LC Profile Seal 1The LC Profile’s computer-aided design goemetry has been engineered to provide reliable sealing from the smallest 1/8” cross-section to the larger 1/2” cross- section. This seal is designed to retrofit into the same seal grooves utilized by a wide range of popular seals having the same seal height and cross-section.

Computer Aided Testing 

Computer-aided testing via FEA (Finite Element Analysis) was performed to optimize the seal design. FEA testing provided conclusive evidence that the LC Profile has a higher sealing force and better contami- nation resistance than traditional sealing designs. Color contours show the radial stress developed in the LC Profile. indicative of high sealing force at the sealing interface. (See Figure 2)
