Test Coupling


R+L HYDRAULICS GmbH has added test couplings to its product portfolio. The new test couplings are designed for testing pressure, lubrication, bleeding air and sampling oil in a wide variety of mobile and fixed position hydraulic applications for industry, construction machinery, agricultural machinery, naval, energy and environmental technology, mechanical engineering, automobiles and rail vehicles. The test couplings can be supplied in a range of materials, e.g., stainless steel. They are compatible with all hydraulic and mineral oils and can be adapted for other media upon request.

Test couplings are usable for both original equipment and retrofits. They offer service personnel and end users of hydraulic applications a simple, safe option for monitoring system pressure, venting the hydraulic system, analysing the degree of contamination and taking representative fluid samples – either temporarily or permanently. The integrated non-return valve allows this work to be carried out under pressure of up to 630 bar and does not require the system to be shut down
