Please refer to Jerry Stachiw’s tome of acrylic ports, he
is adamant about not using O-rings with submersible domes and ports…they cause
a localization of stress. He wife reiterated and was adamant about this
point during the Holland conference. Stachiw’s numerous experiments that
proved this point are well documented in the book. The standards for
acrylic domes and ports installation in subs were developed from his work (and
if I remember correctly, which he wrote).
While early subs used O-rings, this was found to be
hazardous so later designs employed gasket material and/or bedding
compounds. These are actually easier to work with that having to cut
O-ring surfaces.
