Alfabiotech 5000 and Yokohama Versatran 350 bar alternative: the Flexline5000 spiral hose
Alfabiotech 5000 and Yokohama Versatran 350 bar alternative: the Flexline5000 spiral hose
The Alfagomma Alfabiotech 5000 is a widely used high-pressure spiral hose for demanding hydraulic applications in the mobile and industrial sectors. Van de Calseyde offers a full alternative: the Intertraco Flexline5000, a four or six wire steel spiral hose meeting ISO 18752 class 350 and, for sizes -16 and -32, also SAE 100 R13 and EN 856 R13.
The Flexline5000 is also a direct technical replacement for the Yokohama Versatran ISO18752-350 bar, a high-pressure isobaric spiral hose previously distributed through FB Hydraulic, now part of the Danfoss group. Both hoses meet ISO 18752 class 350, with identical working pressure, temperature range, and fluid compatibility.
The Flexline5000 is available in all common dash sizes and is fully compatible with our fitting range.

Frequently asked questions
Is the Flexline5000 a direct replacement for the Alfagomma Alfabiotech 5000? Yes. Both hoses meet ISO 18752 class 350, have identical temperature ranges and are compatible with the same fluids, including biodegradable hydraulic oils. The Flexline5000 offers a higher certified working pressure of 380 bar on sizes -10 and -12, compared to 350 bar on the Alfabiotech 5000.
Which fittings should I use with the Flexline5000? Van de Calseyde supplies matched fittings for every size. Contact us for advice based on your existing installation and pressure class.
Does Van de Calseyde also supply custom-assembled hoses? Yes. We assemble hoses to length in our workshop in Ghent, including crimping and quality control.
Is the Flexline5000 available for mining applications? Yes. The hose carries MSHA approval for use in underground mining.
What is the difference with the Flexline6000? The Flexline6000 is rated for 420 bar (ISO 18752 class 420 / SAE 100 R15) and is the right choice for the most demanding applications up to 6000 psi. See also our Flexline6000 page as an alternative to the Alfagomma Alfabiotech 6000.
Is the Flexline5000 an alternative to the Yokohama Versatran 350 bar?
Yes. The Yokohama Versatran ISO18752-350 bar and the Flexline5000 meet the same standard and are technically interchangeable. The Versatran was distributed through FB Hydraulic, which was acquired by Danfoss in December 2025. For supply continuity, the Flexline5000 is available directly from stock in Ghent.
