Error reduction through colour in hydraulics

Coloured marking rings for measuring couplings and ready-made measuring hoses reduce errors during maintenance of hydraulic systems

After successfully introducing solutions for marking hydraulic quick couplings last year, STAUFF is now taking the next step with the colour marking of hydraulic test equipment in the STAUFF Test series :

Hydraulic test couplings and test hose assemblies in the STAUFF Test 20 and 15 series made of steel and stainless steel have a groove in the knurled cap defined as standard. The lettering STAUFF Test is located all around this groove. In additional to that, this groove has no technical function.

From now on, operators can use this groove to further reduce the potential for errors when servicing and maintaining hydraulic systems. For this purpose, simple coloured rings are inserted into the groove. In this way, different hydraulic systems or pressure ranges can be identified within a system, different hydraulic media or coupling types can be marked or suitable positions for fluid sampling, system venting and filling can be indicated.

These rings are available in five different colours.

Flexible Retrofit Marking

This marking, which can be flexibly retrofitted in the work process, has several advantages over solutions where the protective caps or couplings are coloured in the plant: Instead of taking defined batches in different colours in advance, only colour rings have to be stocked, so that no double stock-keeping is necessary. There are only minor additional costs.

The rings are made of thermoplastic polyurethane (TPU) and can be stored for up to 10 years if properly stored. TPU has a high abrasion and wear resistance and is resistant to all media normally used in hydraulics, as well as other oils, greases and a variety of common solvents. The rings also have very good UV resistance.

The following FAQ section provides answers to the most important questions about hydraulic test couplings and test hose assemblies with colour coding.
