The 1594EGASKET is a silicone gasket kit supplied as a 2-pack and described by the manufacturer as a gasket kit for 1594 "W" enclosures. It is the replacement gasket listed in the 1594 series ordering table for the E size, the 167 x 107 x 65 mm enclosures: 1594EBK, 1594EGY, 1594ESBK, 1594ESGY, 1594EWBK and 1594EWGY.

For owners of the water-tight 1594EWBK or 1594EWGY, it provides a fresh seal when the original gasket is damaged or has been removed during service. For standard and economy E-size boxes, the series literature notes that their IP54 rating can be upgraded to IP66 with gaskets and screws with o-rings; the matching o-ring machine screws are sold as 1594WMS100 in packs of 100. Series photos show the gasket installed on the lid.

The gasket is made of silicone, and the part page lists an IP65 rating. It is RoHS and REACH compliant, packed in shrink wrap, and has a shipping weight of 0.02 lbs (0.01 kg). Identifiers are UPC 623980992648 and UNSPSC 39121301.

Gaskets are size-specific within the series. Choose the 1594EGASKET only for E-size enclosures; the D size uses 1594DGASKET and the smaller sizes have their own gasket part numbers.
