The 1554XGASKET is a replacement lid gasket for Hammond 1554 and 1555 series enclosures in the X and XA sizes. It is intended for panel builders, OEM engineers and maintenance teams who need to restore the seal on an existing X or XA size enclosure after the original gasket has been damaged, compressed or removed during modification work. The part is listed by the manufacturer as "GASKET FOR 1554/1555 X/XA".

Each gasket is a single, one-piece seal made from high temperature, U.L. listed silicone, so there are no joints or seams to fail around the perimeter of the lid. The 1554XGASKET is sold in pairs, giving you a spare or a second enclosure's worth of sealing from one order.

The part drawing shows an overall gasket outline of 295.90 mm (11.65 in) by 195.90 mm (7.71 in), with a second outline dimension of 260.29 mm (10.25 in) by 145.29 mm (5.72 in). Section A-A on the drawing gives profile dimensions of 9.10 mm (0.36 in) and 14.50 mm (0.57 in). The shipping weight is 0.02 lbs (0.01 kg).

Use the 1554XGASKET only with the X and XA sizes; the replacement gasket series lists a dedicated gasket for each group of 1554 and 1555 enclosure sizes, covering the 1554, 1555 and 1555F series. The gasket is RoHS compliant and REACH compliant, and carries UPC 623980403267.
