Rubber plug grommets close specified panel openings. A panel plug is not automatically a suitable laboratory stopper or closure for a container of hazardous chemicals.
For a panel closure, check the cutout, panel thickness and retaining profile. For a fluid container, use a closure documented for the connection, substance, pressure and temperature involved.
Select the compound using the actual exposure requirements. Material options may include EPDM, NBR (Nitrile), neoprene or silicone, but no family is compatible with every chemical. Verify retention and any required seal in the assembly and follow the product's inspection and replacement instructions.
