All 3600     2 rolls 237-3859 Tape and 2 rolls 237-3860 Tape    
All 3500     1 roll 237-3859 Tape and 1 roll 237-3860 Tape    The tape can be applied easily to a connection. A single wrap is sufficient to seal a joint from fuel or oil spray. A clear film must be peeled off the adhesive side of the tape before the tape is applied to a joint. The foil side of the tape will be visible after the application of the tape. Refer to Illustration 1 for the correct application.

Although the tape will prevent fuel or oil spray, fuel or oil may still leak from the tape. The tape should be applied so that any potential leaks will not fall on a hot surface or a heat source. Refer to Illustration 2.

Note: The tape should not be reused. New tape should be applied if the old tape is removed in order to service the engine.The standards organization does not require the tape to be classified with a Society Type Approval. However, the tape must withstand the temperatures of an operating engine and the adhesive should be resistant to fuel and to oil. There are other tapes that can be used as screening material. Use the following types of tape: 3M aluminum foil tape 425 and 427 and Venture Tape Corporation VentureClad 1577CW. These tapes are not available through the Caterpillar parts system. These tapes are another option for screening fuel and oil line connections.The tape is meant only as a backup for safety. The proper torque must be applied to all fuel line connections and all oil line connections. Ensure that all connections have the required torque before applying the tape.
