HERMETICALLY SEALED AND PRESSURE TIGHT CONNECTORS
Hermetically sealed and pressure-tight connectors are one of our specialties. Based on decades of experience, we can deliver
almost any type of connector in a hermetically sealed version.
Please note that our sealed and unsealed connectors have identically dimensioned mating areas and thus are
intermateable.
Distinction must be made between liquidtight and gastight connectors limiting the gas-tightness to fixed connectors
(receptacles and panel plugs) and their mounting areas.
IEC 60529, BS 5490 and DIN 40 050 standards classify the degree of «Ingress Protection» (IP), from water (dripping water,
splashed water, streaming water and continuous immersion) as well as protection from dust.
Our range of liquidtight connectors includes styles like DEU, DBEU, DBPU and similar. Liquidtight connectors are rated IP68 to
a depth ≥ 1m in water.
Hermetically sealed connectors are gastight. Therefore they exceed the IP68 rating (which is a definition limited to liquids).
Hermetically sealed connectors can be used under water to a depth of 80 meters (or more with protective covers. However
specific testy is then required)
The sealing material limits the working temperature range to approximately -25°C to +135°C. We highly recommend that the
application falls within these limits. If not, please check with us about using special materials.
The IEC standard defines the gas-tightness of connectors in terms of leakage rates ranging between a few mm

exceed the value of 0.36 mm
Our hermetically sealed connectors meet all requirements of the relevant standards. At the highest sealing level, the leakage
rate is between 0.004 and 0.036 mm
the US MIL Standards and exceeds the IEC Standards by a factor 100.
Prior to shipment, all hermetically sealed receptacles, panel plugs and feed-through connectors are subject to a vacuum test.
Helium is used as a tracer gas, and this non-destructive test is carried out similarly to MIL STD 1344, Method 100B, and IEC
standards 60068-2-17 Test Qk: «Sealing tracer gas method with mass spectrometer» (Test method 3, Alternative b). In this test,
the vacuum chamber is sealed by the test connector and the spectrometer shows the leakage rate directly. FISCHER tests for

mbar l/s or ≤10
All panel connectors, with the exception of a few coaxial and high voltage connectors, are available in
hermetically sealed versions.
FISCHER connectors are sealed in the following fashion:
