Explosion-Proof Wire Bushings

A process fluid release at the Valero Port Arthur refinery in Texas triggered a significant fire event in early 2026. Weeks later, a separate blaze broke out at a chemical plant in Pasadena, Texas. These incidents made headlines, but for engineers and systems designers producing solutions for hazardous locations, they were only reminders of the […]

Seal tight connectors, also referred to as Sealtite connectors are electrical cable glands used in hazardous locations. Wire or cable passes through the center of the fitting with a locking nut that tightens to the outside diameter of the cable jacket. Various configurations are available, each with hazardous area ratings. Seal tight connectors offer a […]

Cable potting involves encasing conductors in an epoxy, liquid, or gel within an enclosure or feedthrough housing. Douglas Electrical Components employs a proprietary hermetic epoxy to seal wire and cable feedthroughs requiring cable potting. Cable potting is often done in-house by OEM’s or through some Douglas competitors. Differences can arise in the potting encapsulation compound, […]

  Douglas Electrical Components wire feedthroughs and line bushings are often compared to wire feedthroughs that are hermetically sealed using conduit cement within a metal housing. Conduit cement is a traditional bonding substance for sealing electrical systems and conduits whereas epoxy in wire feedthroughs and line bushings can be more suitable for preventing the entry […]
