Bulb trim is specified according to seal dimensions and weight, durometer and shape, and rubber compound. Depending upon the application and industry, parameters such as temperature range, flammability, and code compliance may be important to consider. Most bulb trim is black, but industrial rubber products in different colors are available.
Bulb trim seals typically have four difference measurements: A, B, C, D, and E. Durometer, a measure of hardness, is given in Shore A. Bulb trim seals also vary in terms of shape and bulb location. Bulbs vary in size and typically have an inch-based inner diameter (ID) and outer diameter (OD).
Some bulbs use 80-durometer rubber, but most feature medium-density EPDM, a closed-cell sponge material that resists moisture and withstands temperature extremes. EPDM also provides a relatively high degree of electrical insulation. Unlike many elastomers, EPDM exhibits superior UV resistance, making EPDM bulb trim a good choice for outdoor applications.
