More Information
Summary:An O-ring for an oil cooler of a CNG engine is provided to increase durability of the O-ring and to reduce manufacturing cost in comparison with the conventional O-ring made of aflas. An O-ring for an oil cooler of a CNG engine includes an inner ring(100) and an outer ring(110). The inner ring is made of a compressible and expandable material. The outer ring covers the outer part of the inner ring to protect the inner ring, wherein the outer ring is made of a metal material and has an opening(112) so as to cover only a portion of the inner ring. The length of the opening of the outer ring is larger than the maximum compression height(H) of the O-ring such that the outer ring is not overlapped when the O-ring is compressed.
