The face is then lapped to 4 light bands. Once installed and operational the carbon/graphite face will actually polish the stainless steel rotor face during the initial minutes of operation. This polishing process ensures a perfect seal and eliminates the necessity of a spray guard. The high density of this composite greatly increases its impact and wear resistance. At a maximum operating temperature of 500° F, the carbon guards against any overheating situation unlike other seals using plastic derivatives. The carbon/graphite flange should never need replacing under normal operation conditions. </div> <div> 2) DOUBLE O-RINGS</div> <div> The nitrile O-Rings are fit inside the stainless steel rotor to guarantee alignment and seal of the rotor to propeller shaft. Nitrile is the material used due to its superior resistance to petroleum products, temperature variations and resistance to tearing. These O-rings are stationary and do not wear. </div> <div> 3) STAINLESS STEEL ROTOR</div> <div> The one-piece stainless steel (Type 316) rotor is slid down and secured to the propeller shaft with double set screws. Precision tolerance are maintained bycomputer controlled lathes. After machining, the rotors are passivated to military specifications for maximum corrosion resistance. The stainless steel rotor should never need replacing under normal operating conditions. </div> <div> 4) DOUBLE ALLEN HEAD SET SCREWS</div> <div> Allen head set screws with cupped ends (to prevent damage to shaft) are threaded into the rotor and secured to the propeller shaft. A second set screw is then threaded into each hole to secure the first screw and to prevent it from possibly backing out. Set screws are treated with a Dri-Loc 204. </div> <div> 5) DOUBLE HOSE CLAMPS</div> <div> Two stainless steel hose clamps are used to secure the bellow at both the stern tube and flange ends. </div> <div> 6) REINFORCED BELLOW</div> <div> Reinforced bellow is resistance to petroleum based products and set retention. It provides the best combination of durability, strength and elasticity. The stern tube end of the bellow is available in 1/4" increments. Both shaft and stern tube diameters are necessary when ordering: (1.75" x 2.75")</div> <div> 7) High Speed  nipple intake for water feed.  Not identified in schematic but it is the vertical nipple
