Chico SpeedSeal compound lets you reliably install a complete explosionproof seal in five minutes. Chico SpeedSeal comes in a self-contained applicator kit that eliminates the need for measuring before mixing. Just pump to mix the material, inject the pre-measured amount, replace the plug and the fitting is sealed. Its that easy. Chico SpeedSeal expands after injection to tightly fill the entire fitting, automatically separating the conductors. The time-consuming and tedious task of packing fiber to separate the individual conductors is eliminated. Once cured, Chico SpeedSeal forms an explosionproof seal around each electrical conductor in Eatons Crouse-Hinds series EYS and EYD sealing fittings, restricting the passage of gases, vapors or flames through the sealing fitting. SpeedSeal is approved for use in Class I, Division 1, Groups C, D and Class II, Division 1, Groups E, F, G.
