    Custom Configurations

    LDI Industries specializes in the design and manufacture of engineered fittings and made to order fitting configurations.

    Our work with Check/Relief Valves and Filter Fittings stand alone, but custom configurations encompass a wide range of industry standards, materials, configurations and finishes. Although not made to stock, LDI's technical staff and diverse manufacturing capabilities enable us to develop fitting solutions to the specific needs of our customers. We machine and assemble product conforming to the following industry standards: DIN, ISO, JIS, and SAE.
