Explosion-Proof Wire Seals
Higher leak test pressures are available upon request for most designs with leak testing with either nitrogen or helium, as the 80 psi or vacuum leak test or other pressure test value shown on many drawings is only a default leak test value and not usually a maximum pressure test rating which can be much higher. Most designs will also seal bi-directionally for either pressures or vacuums. Check with PAVE sales engineering to request higher pressure leak testing or pressure testing in opposite direction shown from the drawings. Cutting the wire length shorter has no effect on the seal integrity.
Higher voltage testing is available upon request for most designs.
Lower temperature ratings can be achieved in most cases by simply changing the o-ring compound to an o-ring with a lower operating temperature rating. Check with PAVE sales engineering or an o-ring supplier for recommended alternate o-ring compounds.

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.
