completecouplinginstallationrequirements.

1. Inspect the gasket, as described in Step 2a on the previous page.

2. Apply a thin coat of Victaulic Lubricant or silicone lubricant to the

gasket sealing lips and exterior. DO NOT use petroleum-based

lubricants on Grade “E” gaskets.

3. Position the gasket over the grooved end of the Vic-Strainer body.

Make sure the gasket does not overhang the end of the Vic-

Strainer body.

3a. Install the access cap. Center the gasket between the groove in

the Vic-Strainer body and the access cap.

3b. Using the “swing-over” feature, install the housings over the

gasket. Make sure the housings’ keys engage the groove in the Vic-

Strainer body and the outside surface of the access cap.

be tightened evenly by alternating sides until metal-to-metal

contact occurs at the bolt pads.
