Honeywell 15PA87 Panel Seal: Technical Overview and Practical Use
The Honeywell 15PA87 panel seal is a specialized accessory designed for toggle switch installations that need a more reliable sealed interface at the panel. In technical terms, this component is used with 15/32-32 UNS threaded bushing toggle switches and is commonly matched with Honeywell AT, NT, TL, TS, and TW Series products. That makes the Honeywell 15PA87 panel seal accessory especially relevant in control panels where environmental exposure, dust, or incidental moisture could affect switch performance over time.
What the Honeywell 15PA87 Panel Seal Is Made For
One of the most useful details about the Honeywell 15PA87 toggle switch seal is its construction. Source data describes it as a corrosion-resistant steel cup washer with a keying tab and a silicone elastomer lining on one side. This layout is not just a mechanical detail. It supports more secure sealing around the switch bushing area and helps protect the mounting point where contamination often starts. The product is also associated with front panel mounting, silicone material, and RoHS-compliant status, which helps explain why engineers often specify this kind of accessory for durable switch assemblies.
Where Honeywell 15PA87 Fits Best
The Honeywell 15PA87 sealing washer is a strong fit for industrial equipment, machine interfaces, transportation systems, and other applications where toggle switches face repeated use. Honeywell support information also notes suitability for panels up to 0.125 inch thick, which is a practical installation detail for enclosure planning. Because it is intended for established Honeywell toggle switch families, the part is best understood as a protective mounting accessory rather than a general-purpose washer.

FAQ
Is Honeywell 15PA87 a switch or an accessory?
The Honeywell 15PA87 panel seal is an accessory, not the switch itself. It functions as a sealing interface used around compatible toggle switch bushings to improve panel protection and mounting integrity.
Which switch families are compatible with Honeywell 15PA87?
Available source material consistently links this part with AT, NT, TL, TS, and TW Series toggle switches. That broad family compatibility is one of the reasons it appears frequently in technical and maintenance discussions.
Why does the material matter on the Honeywell 15PA87 panel seal?
The silicone elastomer lining helps create a more effective seal at the mounting surface, while the corrosion-resistant metal structure adds mechanical durability. Together, those details support longer-term reliability in demanding panel environments.
When should engineers specify 15PA87?
It is most relevant when a toggle switch installation needs improved sealing at the panel interface, especially in applications exposed to dust, vibration, or light moisture. It is also helpful when maintaining consistency across Honeywell toggle switch builds.
