The 1590Z231G supplies two replacement silicone gaskets for the 1590Z231 family of 200 x 230 x 110 mm diecast aluminum enclosures: natural 1590Z231, black 1590Z231BK and gray 1590Z231GY. Keep a pack on the shelf for maintenance, for enclosures that are opened frequently, or for boxes that have been modified in the field.

The gasket is the replaceable one piece silicone rubber seal that fits the tongue and groove joint of the 1590Z series, protecting against dust and water ingress, with a temperature rating of -40C to +150C (-40F to 302F). The drawing (reference G231) specifies silicone rubber, with an alternate material of Shin-Etsu KE-931U & KE-941U in a 1:1 mixture. The part page lists an IP66 rating.

Listed size is 8.78 in x 7.74 in x 0.14 in (223 mm x 197 mm x 4 mm). The drawing gives 8.775 in [222.88 mm] by 7.741 in [196.63 mm] outside, with a section of 0.138 in [3.50 mm] by 0.148 in [3.75 mm]. Each pack ships in a bag, with a shipping weight of 0.02 lbs (0.01 kg).

The 1590Z231G is RoHS and REACH compliant. Other spares for the same enclosure are SC564-12 lid screws, the 1590Z231PL inner panel and SCGM6-20 panel screws.
