Explosion-Proof Wire Seals Specifications

Explosion-Proof Wire Seals

MOST PAVE HERMETIC SEALS ARE BI-DIRECTIONAL SEALS FOR VACUUM OR PRESSURE.

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.

Online drawing files require the use of Adobe Acrobat Reader version 5.0 or later version software to open to view, print or to download from the Acrobat save button. Acrobat Reader can be downloaded free of charge from the Adobe Web site at www.adobe.com.

Upon your email request, a 3D CAD file of most of our drawing can be emailed to the customer for their design use. These 3D models can be supplied in either SolidWorks, STEP or IGS file formats. Please specify your file format preference if any.

PAVE-Optic-SealTM PAVE-Flex®

While all PAVE products will comply with helium leak rating from <10-6 cc/sec to 10-9 cc/sec (air equivalent) depending upon design, PAVE also uses more cost effective air bubble in fluid leak testing typically at 80 psi (5 bar). Special high pressure testing up to 10 k psi (600 bar) is also available.

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.
