How's this for a surefire success? This thimble-size shield works inside a n automobile engine. It clings to a pulsing valve stem, prevents excessive loss of engine oil—yet allows enough oil to properly lubricate t h e stem. Obviously, a tough job for a tiny part. To d o this critical job, rubber seemed the likely choice. But it would have to be a very special kind of rubber. It would have to withstand constant contact with oil, intense vibration a n d compression, wide temperature extremes and great tension. Material selected:

CHEMIGUM,

the nitrile rubber that

Hundreds of thousands of these valve stem shields are now i n use — meeting every operational requirement. And t h e constant uniformity plus t h e easy processability of C H E M I G U M make their production practical and profitable. What can CHEMIGUM d o for your product?
