Access Ports provide access to desiccant, data, accessory storage areas or for diagnostic testing of contents in containers.


AGM access ports are designed with ease of installation in mind. Simply cut an appropriate sized hole in your container wall, insert the port, and secure it with the provided nut and washer.

Yes. All AGM access ports provide a removable cover that seals, as well as gasketing to seal the port housing to the exterior surface of the container it is installed on.

Yes. All AGM access ports have provisions for safety wiring.

AGM currently offers three standard sizes of access ports with nominal diameters of 2″ (TA475-PORT), 4″ (TA495) and 5″ (TA595). While it is possible to make ports of other diameters, it is usually cost prohibitive unless production volumes are significant. Please contact our Engineering Department with any special requests you might have.

Yes. The standard cover is made from stainless steel and passivated. The housings on the TA475-PORT and TA495 are conversion coated while housing on the TA595 is hard, black anodize. However, virtually any other finish, including paint, is available upon request.

Yes. The TA475-PORT and TA495 are rated to 5 psid while the TA595 is rated to 2.5 psid.

The covers of all three size access ports are provided with lanyards so they can hang free while the port is in use without the fear of misplacing, dropping, or otherwise losing the cover.

Yes. Replacement covers are for sale for all of our access ports, desiccant baskets, and records holders. The replacement is easily accomplished in minutes using common hand tools. Please specify the part number of the item you are requesting a replacement cover for as we make many custom items with unique part numbers.

Yes, we do. Many of our customers work with us to develop custom applications using our access ports. These features include: extra long cover lanyard, special finishes, special gasketing, stainless steel housing and mounting nut, RFI protection, and extended wall thickness housing.

Yes. All three sizes of access ports are available with a cover that will accept a valve or humidity indicator. Existing port installations can be modified to accept a valve or humidity indicator by installing a replacement cover with the appropriate mounting hole, or by cutting the appropriately sized hole in the cover (4″-port and 5″-port only). Replacement covers are available from AGM.
