Manville's JM Clipper oil seals perform better than competitive designs, especially in dirty environments or where shaft and bore conditions are less than ideal. This is achieved by replacement of troublesome metal reinforced casings with a flexible aramid fiber reinforced composite casing.

As an added benefit, this hard yet resilient casing simplifies installation by allowing the installer to easily tap the seal into place with a mallet. Try this with a traditional metal cased seal and you risk permanently damaging the seal, which is the reason many metal cased seals require special installation tools and procedures. A switch to Manville's JM Clipper seals will save you time and money by reducing downtime, speeding repairs and reducing housekeeping requirements by sealing where other seals have leaked.

Advantages of Manville's JM Clipper Oil Seals:
- Tolerate rough bore finishes while accommodating a wide range of bore tolerances
- Flexible outer diameter acts as a gasket virtually eliminating the possibility of leakage through the seal itself
- Totally non-corroding in storage and service
- Easy to remove and install with no special tools or skills
- Available in over 5,000 pre-split sizes for instant installation without equipment disassembly
- Interchangeable with most brands

The non-metallic type JM Clipper Oil Seal offers the following unique construction benefits:

Characteristic Benefit Aramid Fiber-Reinforced Composite Will fit a wider range of bore tolerances and finishes, resulting in lower machining costs and easier installation. It resists corrosion and takes more abuse eliminating installation damage. Integrally Molded Unit Gives better ID. to OD. concentricity resulting in less potential leakage and shaft wear. Stainless Steel Garter Spring Provides more uniform lip load and resists corrosion. Specially formulated elastomer lip with designed flexibility Minimizes friction resulting in less shaft wear and follows shaft eccentricity.
