B-LINE SPB – Frequently Asked Questions

1) What size opening does the Eaton B-Line SPB hole seal cover?
The B-Line SPB is a 1.75 inch diameter hole seal, sized for a standard pushbutton or conduit opening in an enclosure wall. Its height is also listed at 1.75 inches, so allow that much clearance behind or in front of the plate when other components are crowded around the opening.
2) Will a B-Line SPB hole seal keep coolant and oil spray out of a control enclosure?
Yes. The SPB is an oil-tight hole seal, so it is built to close off an unused pushbutton or conduit opening against oil and liquid spray rather than just cover it cosmetically. That is the difference between this and a plain snap-in plug: it is intended for machine-tool and washdown-adjacent enclosures where an open knockout would let fluid in.
3) Can I use a hole seal to close a knockout where a pushbutton was removed?
That is exactly what the SPB is for. When a pilot device or pushbutton comes out of a panel door during a retrofit, the 1.75 inch oil-tight seal closes the opening so the enclosure keeps its integrity instead of leaving a live hole for dust and fluid. Same use for an abandoned conduit opening.
4) Will the SPB hole seal match my existing gray industrial enclosures?
Finish is ANSI 61 gray polyester powder coat, the standard gray used on most industrial control and junction enclosures, so it blends into a typical panel shop or plant fleet without a repaint.
5) What part number do I order for the B-Line oil-tight hole seal?
Order Eaton B-Line model SPB. It is a single model, the 1.75 inch oil-tight steel hole seal in ANSI 61 gray, so there are no finish or size options to specify on the order.
