B-LINE S400SS – Frequently Asked Questions

1) What does the Eaton B-Line S400SS hole seal actually do in an enclosure?
The S400SS is an oil-tight hole seal. It closes off an unused opening in an electrical enclosure, a vacated pushbutton hole, or a conduit opening, so dust, oil spray and washdown cannot get into the panel through the hole. It is a blank-off part, not a fitting, so nothing passes through it once it is installed.
2) What size opening does the B-Line S400SS hole seal cover?
It is the 4 inch seal in the series, with a product diameter of 5.12 inches and a height of 5.125 inches. The outside dimension is larger than the hole it covers, so measure your existing opening, not the seal, when you are matching a part.
3) Is the S400SS hole seal stainless steel or painted steel?
Both, in effect. The body is stainless steel and it is finished in ANSI 61 gray polyester powder coat, which is the standard industrial enclosure gray. On a painted ANSI 61 panel it blends in; if you need bare stainless to match an unpainted washdown enclosure, this painted version will stand out.
4) Is the B-Line S400SS oil-tight hole seal UL listed?
UL is the certification carried on the S400SS. That matters on a panel where an inspector is checking that every opening in the enclosure is closed with a rated component rather than a shop-made cover plate.
5) Can I use this hole seal to close a knockout left after removing a pushbutton?
Yes, that is one of its stated uses. The S400SS covers pushbutton openings and conduit openings as well as general enclosure openings, and the oil-tight construction keeps coolant and oil mist out of the panel in a machine-shop environment.
6) What part number do I order for the 4 inch B-Line oil-tight hole seal?
Order Eaton B-Line S400SS. That is the full manufacturer part number for the 4 inch stainless oil-tight hole seal in ANSI 61 gray, and it is the only configuration under that number.
