The 1553WBGASKET is a 2-pack of replacement silicone gaskets for 1553WB enclosures in the 1553W water-tight hand-held series. The 1553W enclosures are designed to meet IP65 and ship with a pre-formed, pre-installed silicone gasket; this pack provides spares for when a gasket needs replacing during service or rework.

According to the series ordering table, 1553WBGASKET is the replacement gasket for both B-size enclosures: the black 1553WBBK and the grey 1553WBGY, each measuring 4.61 x 3.11 x 0.98 in (117 x 79 x 25 mm). The drawings for those enclosures list the silicone pre-formed gaskets (Pkg 2) as an accessory. Key details of this part:

• Material: silicone
• IP Rating listed on the part page: IP65
• Size: 4.44 x 2.93 x 0.07 in (113 x 74 x 2 mm)
• Shipping weight: 0.02 lbs (0.01 kg), packed in a bag
• RoHS and REACH compliant

On the 1553W enclosures the assembly screws are located outside the gasket channel, and the enclosures use stainless steel machine screws in brass bushings, which the series describes as suited to repetitive assembly and disassembly; keeping a spare gasket on hand supports that kind of repeated opening. For the C size, order 1553WCGASKET instead. The series also cautions that some chemicals, including certain greases and oils, can affect plastic, so confirm compatibility before using any lubricant near the enclosure.
