ASME PVHO only recognizes a narrow set of STANDARD geometries, which include round flat discs, spherical domes and cylinders. All other geometries are considered NON-STANDARD and cannot be ASME PVHO Certified.


Beyond the PVHO Selection, HYDROSPACE also offers full range of high precision acrylic shapes for medical, instrumentation or camera housings. Our in-house control of all processes and machining capabilities guarantees the quality and performance of all custom fabricated components.
