Explosion-Proof Wire Seals
Most Pave Hermetic Seals Are Bi-directional Seals for Vacuum or Pressure
A wide range of either UL 1203 Wires threaded NPT or metric or non-threaded cylindrical metal sleeves, explosion-proof sealed line bushings are available to ATEX, FM, UL and CSA certifications using an almost unlimited choice of wires, cores or cable types, both electrical and fiber optic. -55C to 90C or 200C. EN 60079-0 and EN 60079-1 standards. See our existing line bushing designs with new designs available upon request.
Line bushings with electrical cables, flex circuits or pin terminals for potentially explosive atmospheres for flameproof enclosures are available to ATEX, EEx d II and DIN EN 60079-0 specifications.
Line bushings can either be threaded with NPT or metric threads or non-threaded push in type with a metal sleeve for flame path block securely locked in place with a retaining ring inserted into a groove.
Line bushings can also be upgraded to exceed ATEX requirements to be a complete hermetic gas block seal with no detectable gas leakage anywhere thru the seal including the wire or core conductor stranding if so required by the customer.
PAVE offers hazardous location sealing cable fittings that are explosion-proof, water and oil-tight, dust ignition-proof NPT threaded plated iron alloy ES sealing hub that are potted epoxy electrical wire assemblies.

HERMETIC EPOXY TEMPERATURE RATING (Epoxy is proprietary and not sold separately)
The PAVE-Seal® epoxy is impervious to most oils, solvents, fuels, freons, gases, etc. Epoxy samples are available upon request for customer’s evaluation for any specific chemical compatibility.
Any type or size of wire or cable may be specified including coaxial cables, thermocouple wire pairs, high voltage wires, fiber optic cable, flat cables, etc. for length.
NO DETECTABLE LEAKAGE THRU CONDUCTOR OR INSULATION.
