Separate Expansion Joint

The separate expansion joint with internal seal is not exposed to the flow drainage passing. However, provisions must be made in the installation for access to the outside packing glad adjustment nuts. These units should only be used in a vertical position and with a roof drain.

Please Note: Do not use with Speedi-Seal and plastic leaders.
