What are access ports?

Document and desiccant ports also referred to as access ports, provide access to documentation or access to desiccant for replacement without needing to open the sealed container. The ability to easily access these ports reduces the potential for damage to equipment by reducing the exposure to any elements.

Access Port Sizing & Specifications

We provide three different sizes of access ports:

While it is possible to make ports of other diameters, it is usually cost prohibitive unless production volumes are significant. Our access ports also come with provisions for safety wiring including a seal on the cover.

If you’re looking for a custom access port, please contact our Engineering Department with any special requests you might have.
