■ Compress the gasket protector slightly and insert it in the coupling.
■ Insert the gasket protector so that its interlocking teeth are not adjacent to the rubber gasket teeth
or steel sleeve teeth. Each of these part’s interlocking teeth should be in a different quadrant.
■ The gasket protector should be centered in the coupling.
Note: The spring tension of the stainless-steel gasket protector will keep it in position.
Stainless-Steel Gasket Protectors
Stainless-steel gasket protectors save dollars by preventing gasket wear and line contamination.
Gasket Protectors
■ The proper position of the grounding strips is opposite of the bolts of the coupling flange.
■ Insert the grounding strip between the inner sleeve and the gasket.
■ Push the grounding strip through until 1" of the strip is showing on both ends.
■ Bend both ends of the strip down over the gasket. When complete, the strip will lay flat
against the gasket.
Static Grounding Strip
Strips provide positive conduction of static across
joints to the system ground…at no extra cost and
without special gaskets.
