Send HydTec the old article number and all available technical information. HydTec checks the current lifecycle and supply status, the manufacturer's successor, verified alternatives, repair or remanufacture, and any retrofit needed to preserve the function. Older drawings and article numbers remain useful references, but the final recommendation is based on critical interfaces and operating limits. The result is stated clearly as either a verified direct replacement or a retrofit requiring defined adaptations.

No. Stock availability and lifecycle status are separate. A product can be temporarily out of stock or have an extended lead time while still being manufactured. HydTec checks current supply information and the product’s confirmed lifecycle status before recommending an alternative or replacement.

A verified direct replacement performs the required function within the confirmed operating limits and fits the critical mechanical, hydraulic and electrical interfaces without planned modification. A retrofit achieves the required function but needs defined changes such as adapters, hoses, couplings, mounting work, wiring or control adjustments. HydTec states which route applies and identifies the required changes before an alternative is approved.

Provide the complete old part number, nameplate photographs, quantity, application and available drawings. The decisive data may also include pressure, flow, displacement, speed, rotation, shaft, flange, ports, controls, voltage, fluid, duty cycle and installation space. HydTec confirms which details are critical for the specific product before recommending a replacement.

Compatibility is checked from the required function and the complete application, not from a nominal size or cross-reference number alone. HydTec compares the relevant operating limits, mounting, shaft, ports, controls, materials, and environmental conditions. Any required adaptation is stated explicitly rather than being hidden behind a replacement number.
