Explosion-Proof Dust Ignition Proof Flexible Conduit Coupling, 3/

Special Features Explosionproof, dust-ignitionproof, watertight; Smooth, rounded integral bushing in each hub protects conductor insulation; Accurately tapped, tapered threads for tight, rigid joints and ground continuity; Heavy duty design resists mechanical abuse; Electrical conductivity equal to rigid conduit on a similar length basis no bonding jumper required; Interior insulating liner protects conductors from abrasion under vibrating conditions; Female end fitting with removable ductile iron union at one end and a female end fitting with a removable brass male nipple at the other end; Used in areas where vibration and movement is a problem, also used in place of rigid conduit in difficult-bend situations
