Note:
1. No O-ring: Penetration of oil and water is not prevented. Use the
Connector with sealing tape. O-ring: Penetration of oil and water is
prevented.
2. Use an SC-P2 Rubber Ring and conduit
washer for SC-21 to SC-25 Connectors.
3. SC-series Connectors must be used with
sealing tape. SC-1M to SC-5M Connectors, however, include an NBR O-ring
that ensures sealing without using sealing tape.

Note: The casings for SC-P2, -P3 and -6 are made of resin. If more sealing
capability is required, use one of SC-1M to SC-5M, which have metal
casings.
Models marked with an asterisk (*) however, can only be used with resin
connectors.
