B-LINE S250SS – Frequently Asked Questions

1) What size knockout does the B-Line S250SS hole seal close off?
The S250SS is the 2-1/2 inch hole seal in Eaton's B-Line oil-tight seal line, so it plugs a 2-1/2 inch conduit knockout or unused pushbutton opening in an enclosure. Overall the seal measures 3.5 inches in diameter and 3.5 inches high, so allow that much clearance around the opening and behind the panel wall.
2) Is the S250SS hole seal oil-tight for a wash-down or machine shop panel?
Yes, it is an oil-tight hole seal, which is what you want on a machine tool or process panel where coolant, oil or spray can find an open knockout. It is UL Listed. The body is stainless steel, so it holds up better than plated steel in wet or corrosive areas.
3) Will the S250SS match the gray finish on my existing Eaton B-Line enclosures?
It is finished in ANSI 61 gray polyester powder coat, the standard gray used across B-Line and most industrial enclosure lines, so it blends with a typical ANSI 61 panel or junction box rather than standing out as a bare metal plug.
4) Can I use a 2-1/2 inch hole seal to close an opening left by a removed pushbutton?
That is one of its stated uses. The seal is made to protect openings, pushbuttons and conduit openings, so if a 2-1/2 inch operator or fitting has been pulled, this closes the hole and keeps the enclosure sealed against oil and debris instead of leaving it taped or plated over.
