The 1594CGASKET is a silicone gasket kit for the Hammond 1594C "W" (water-tight) heavy duty ABS enclosures, supplied as a 2-pack. It is the replacement gasket listed in the 1594 Series ordering table for the 1594C size, whose enclosures measure 106.5 mm long, 66 mm wide and 45 mm deep. It suits maintenance teams and OEM builders who reopen sealed boxes and need a fresh lid seal.

The gasket is made of silicone and carries an IP65 rating. In the 1594 family, the water-tight versions (1594CWBK, 1594CWGY) are molded in flame retardant ABS and have been tested to and meet IP66 ratings; their lids fasten with four M3 x 0.5 - 0.71 in (18 mm) long Phillips machine screws threaded into integral brass bushings.

The series data also notes that standard and economy 1594 versions, rated IP54, can be upgraded to IP66 with gaskets and screws with o-rings. For that upgrade on a 1594C box, pair this gasket with the o-ring machine screws sold in packs of 100 as 1594WMS100.

The 1594CGASKET is RoHS and REACH compliant, ships shrink wrapped and has a shipping weight of 0.02 lbs (0.01 kg). Keep silicone and enclosure away from strong solvents, some greases and oils and other chemicals Hammond lists as harmful to its plastic enclosures, and use only plastic-safe cleaners on the enclosure.
