Quality assurance of hydraulic hoses – procedures that ensure high quality

Quality assurance

At Hymatik, quality assurance of hose assembly at our workshop in Odense is a core focus. We primarily use products from Parker Hannifin, which are known for high, documented quality, traceability and accompanying documentation. Our entire stock management follows the FIFO principle (first-in, first-out), so you receive new, fresh goods rather than older components that may have been sitting too long. This delivers consistent results and increases the operational reliability of your hydraulic systems.

Quality assurance of hose assembly

When we crimp hydraulic hoses, we prioritise safety, quality and cleanliness from the first step to the last. We use only approved combinations of hoses, couplings and fittings – either from the same manufacturer or components that have been tested and approved to work together. Cleanliness is part of our standard procedures, because clean hoses extend service life and ensure stable operation without unnecessary pressure increases or wear. All hoses are labelled with a PTS marking, so traceability is intact and an identical hose can be ordered quickly when replacement becomes necessary. Read more about PTS.

Procedure for crimping hydraulic hoses

Based on the procedure described below, all hydraulic hoses produced will meet the ISO 19/18/12 standard.

1. Check components. First, we gather all the components we need. We check that they are the correct ones and that they are free of defects.
2. Marking of fitting. If the customer wishes, the end of the fitting is marked with the customer's item number and date.
3. Cut hose. We measure the hose to the correct length and cut it.
4. Blowing and marking. Once the hose has been cut to the correct length, we blow it through from both ends to clean it. Each end of the hose is then marked with a yellow marker to show how far the ferrule should reach on the hose.
5. Push on fitting. We push the fitting onto the hose until the yellow mark is flush with the edge of the fitting. This is the visual indicator for Hymatik and our customers that the assembly is correct.
6. Crimping. We crimp the fittings onto the hose using our crimping machine, based on the selected diameter. Hymatik's staff and workshop are approved by Parker Hannifin, so we ensure that everything is done according to Parker's specifications.
7. Sealing. The hose is blown through from both sides once again before we fit caps on both ends to ensure that the hose stays clean.
