Box or Enclosure Wall Conduit or Tubing Application: A series of nonmetallic fittings designed to provide a liquidtight seal when terminating liquidtight nonmetallic conduit (U.L. Type B) or liquidtight nonmetallic tubing to a box or enclosure with knockout opening or a threaded hub. * Rugged low profile nonmetallic body and gland construction (1); the fitting is equipped with a steel locknut to firmly secure fitting to box or an enclosure and a sealing "O" ring. * Captive sealing "O" ring (2) with predetermined compression for a reliable seal at enclosure. * Fitting ferrule designed to accept variations in conduit inside diameter and is tolerant of field conduit cuts (3). * Ferrule profile designed to reduce friction between conduit I.D. and ferrule (4) allowing conduit to seat properly for an effective seal. * Outer surface of clamping fingers provided with friction reducing ridges (5) for ease of installation; the inner surface is designed with conduit biting teeth to enhance clamping and sealing action (6). * Performance of fittings tested to simulate adverse installation conditions. * Provides a double sealing action (7). * Elongated gland nut profile (8) designed to provide additional strain relief for 90 pull and an easy hand grip. 107 * Performance of fitting unaffected by exposure to detergents, cleaners, and sanitizers commonly encountered in food processing plants and typical industrial environment; also unaffected by cutting fluids, wiring pulling compounds and Marine environment. * Meets industry standards for cold impact and simulated hammer blow. Standard Material/Finish: * Body Gland--weather stabilized thermoplastic (black). * "O" Ring--nitrile (blue) * Locknut--Steel/electro-zinc plated * Material temperature rating-- thermoplastic -40C to 105C. * Material Flammability Rating: U.L.94-V2. Conformity * CSA C22.2 #227.2 & CSA C22.2 #227.3 * U.L.514B * Watertight requirements of NEMA Type 4 and Type 4X. * Federal Standard H-28 (NPT threads) * There is no CEC Rule to use Nonmetallic liquidtight conduit and fittings in Class I, Zone 2 or Class I, Division 2; Rule 18-202 (4) (b) Class II, Division 1; Rule 18-252 (4) Class II, Division 2; Rule 18-302 (4) Class III, Division 1.
