Watertight & Airtight Doors


At WK, watertight (WT) or airtight (AT) means zero leakage, no matter the door size or design pressure. Whether your door is designed to be submerged 500′ underwater or prevent air leakage from a BSL-4 laboratory, we’ve got a cost effective solution for you. WK has designed more custom watertight & airtight doors than any other company in the US, so you can be assured of the right door for your application.

Any of our doors can be supplied with power operation, and most can be designed for any number of special design considerations including blast, ballistic, shock, vibration, radioactive, seismic, chemical, tornado, and high pressure requirements. Most can be designed for either water or air pressure. Both single and double panel doors are available for most applications.
