Series 37 environmental backshells from Glenair are designed to be fully immersion able, water-tight and splash proof.
Submersible: Glenair Cable Sealing Backshells offer excellent immersion capability when used with impervious jacketed cables. A resilient grommet which fits into a counterbore in the backshell compresses and seals against the cable jacket when the strain relief is tightened. This design of cable sealing backshell is described as "submersible" and is also available in split-shell configurations.
Water-Tight: Glenair offers an economy version, too. This Cable Sealing Backshell provides a resilient grommet as an integral part of the cable strain relief; it is described as "water-tight" throughout this catalog.
Splash-Proof: For applications requiring only moisture resistance and sealing against dust, Glenair offers Environmental Resisting Backshells. An effective sealing barrier is created by a resilient grommet at the backshell cable entry. This backshell design is described as "splash-proof".
