The 1590Z233G is a two-pack of replacement gaskets for the 280 x 230 mm 1590Z233 diecast aluminum enclosures in natural, black (1590Z233BK) and gray (1590Z233GY). It lets maintenance crews and OEM assemblers restore the lid seal without replacing the enclosure.

In the 1590Z series the gasket is a replaceable one piece silicone rubber seal that fits the tongue and groove joint between box and lid and protects against the ingress of dust and water. The series specifies a temperature rating of -40C to +150C (-40F to 302F), and the gasket is designed for enclosures that see repetitive opening and closing.

The part page lists the size as 10.88 in x 8.92 in x 0.14 in (276 mm x 227 mm x 4 mm) and a shipping weight of 0.06 lbs (0.03 kg). New 1590Z enclosures ship with the gasket loose inside rather than pre-installed, so the same fitting step applies when a replacement from this pack is seated in the groove before the four recessed stainless steel lid screws are tightened.

The 1590Z233G is RoHS and REACH compliant. Matching spares for the enclosure include SC599-12 extra lid screws, the 1590Z233PL inner panel and SCGM6-20 panel screws.
