CFKS Nitrile Round Rubber End Cover 14*4 Transmission End Cap EC Oil Seal
The CFKS 14×4 Nitrile Round Rubber End Cover is a premium static boundary component designed specifically for compact power transmissions, gear-reduction units, and electric motors. By encapsulating a rigid internal carbon steel skeleton within a highly durable Nitrile (NBR) elastomeric jacket, this EC-style blind plug provides an absolute, interference-fit barrier. It prevents internal transmission lubricants from weeping while actively excluding environmental dust and abrasive grit from breaching delicate bearing cavities.
-
Absolute Static Sealing: The fully rubberized 14mm outer diameter naturally conforms to minor housing bore imperfections, thermal expansion, and high-frequency machine vibration.
-
Compact 4mm Axial Profile: The slim 4mm width is optimized for shallow transmission housing bores where internal clearance between the plug and the rotating shaft end is strictly limited.
-
Corrosion-Proof Exterior: The continuous Nitrile coating completely isolates the internal metal reinforcement, eliminating the risk of galvanic corrosion between the plug and the aluminum or cast-iron housing.
