B-LINE S150 – Frequently Asked Questions
1) What size opening does the Eaton B-Line S150 hole seal cover?
The S150 is the 1-1/2 inch hole seal, so it plugs a 1-1/2 inch knockout or pushbutton opening in an enclosure. The seal body itself measures 2.5 inches in diameter and 4.375 inches in height, so allow that much clearance around the hole and inside the enclosure.
2) Will an oil-tight hole seal keep coolant and washdown spray out of a control enclosure?
That is what the S150 is built for. It is an oil-tight hole seal, so it closes off an unused pushbutton or conduit opening against oil and liquid ingress rather than just capping it cosmetically. Steel construction and a painted finish let it sit in a machine-shop or plant environment alongside the operators it replaces.
3) Is the B-Line S150 hole seal UL Listed?
Yes. The S150 carries a UL Listed rating, which is usually what an inspector or a plant electrical standard wants to see on a closure used in a control enclosure.
4) Will this hole seal match the gray finish on my existing control panel?
The S150 is finished in ANSI 61 gray polyester powder coat, which is the standard gray used on most industrial control enclosures and panel shop equipment. Against a standard ANSI 61 enclosure it blends; against a white, beige or stainless enclosure it will read as a different color.
5) Steel or plastic hole seal for an unused pushbutton hole?
The S150 is a steel seal, so it stands up to impact and heat better than a plastic snap-in plug and keeps the panel face consistent with the metal enclosure around it. A plastic plug is fine for a dry, low-abuse indoor box; for an oil-tight machine control station where coolant or solvent can hit the panel face, the steel oil-tight type is the one to use.
6) Can I use a hole seal to close a conduit opening I am no longer using?
Yes, that is one of the stated applications for the S150 along with pushbutton and general enclosure openings. When a control device gets removed or a conduit run is abandoned, the seal closes the 1-1/2 inch hole so the enclosure keeps its integrity instead of leaving a live opening.
