1-3Unions, Sealing Fittings, FlexibleCouplings, Elbows, Drain/Breather,Close-Up Plugs: Explosion-ProofUNILETS® for Use with Threaded Metal Conduit.

Features: All Fittings• Explosion-proof, dust-ignition-proof.• Smooth, rounded integral bushing ineach hub protects conductor insulation.• Accurately tapped, tapered threads fortight, rigid joints and ground continuity.Features: Non-Expansion UnionsOConcentric ring interlocked design of1/2", 3/4" and 1" sizes makes possiblesmaller diameter, allowing use in tighterspaces. 1-1/4" and larger UNY sizes haveremovable male nipple.• Choice of malleable iron or aluminum.Features: Expansion Unions©One-piece design eliminates need fordisassembly during installation.• Telescoping cylinder within cylinder de-sign permits expansion or contraction.• Standard or long types available.• Small external diameters- excellent inrestricted areas in wiring of pumps, mo-tors, and other equipment.• Internal phosphor bronze "bondingjumper" ring assures positive ground be-tween telescoping cylinders.Features: Sealing Fittings©Raintight construction.• Removable nipple in male sealing fittingmay be used interchangeably in top orbottom hub.• EYS- for sealing vertical conduit. Largeopening for damming and filling.• Expanded Fill EYSEF/EYDEF- allow upto 40% conduit fill in compliance with theNational Electrical Code.• EYSF/EYSM- for sealing vertical con-duit. Large opening for damming and filling.• ESUF/ESUM for sealing vertical or hor-izontal conduit. Pouring spout rotates 90°.Removable cover provides full access fordamming. 2-1/2" thru 4" sizes havethreaded cover openings for damming.• EYF/EYM- close radius type for sealingvertical or horizontal conduit runs.• EYDM Drain Sealing Fittings- closeradius type for sealing vertical conduitruns. Access cover has drain valve forautomatic draining of water accumulationabove the seal.• SF/SFM Drain Sealing Fittings- for seal-ing vertical conduit runs. Provide contin-uous, automatic draining of wateraccumulation above the seal.• Kwiko® sealing cement is a specially for-mulated water soluble powder. Mixed tothe proper proportions, it is poured in seal-ing fittings and hardens to contain and re-

strict the passage of gases and explo-sions in classified areas.• Fiber Filler-makes dams around and be-tween all conductors to prevent sealingcompound from leaking while beingpoured in its liquid state.Features: Sealing HubsO UL Listed for use in hazardous locationswhen Kwiko® Sealing Compound orGrouse-Hinds Chico® A Sealing Com-pound are used to make the seal.Features: Flexible Couplings©Heavy duty design resists mechanicalabuse. Watertight.• Electrical conductivity equal to rigid con-duit on a similar length basis—no bondingjumper required.• Interior insulating liner protects con-ductors from abrasion under vibratingconditions.• EXGJH- both end fittings are female,each furnished with a removable malenipple.• EXLK- female end fitting with union atone end plus a female end fitting with aremovable male nipple at the other end.Standard Materials• UNY and UNF (Non-Expansion)Unions, 1/2" thru 1": steel or aluminum.1-1/4" thru 6": malleable iron or aluminum.• UNY and UNF Expansion Unions: steel.• UNL Unions: malleable iron and steel.• EYSF/EYSM, EYF/EYM and EYDMSeals: malleable iron or Almag 35aluminum.• EYS, EYSEF/EYDEF, ESUF/ESUMand SF/SFM Seals: malleable iron.• EYD and EYS Seals: Grayloy-iron.• EXGJH and EXLK Couplings, 1/2" thru2": outer bronze braid, inner brass corewith insulating liner; 2-1/2" thru 4": outerstainless steel braid, inner stainless steelcore with insulating liner.
