QUICK COUPLINGS

Q.SAFE QUICK COUPLINGS INTRODUCTION Q.Safe is the Manuli Hydraulics offering for quick coupling applications. Composed of an ever-expanding range of products, the Q.Safe brand has rapidly become an industry byword for quality and performance. The entire Q.Safe product range is manufactured with our E-Coat 500 treatment which provides an environmentally friendly surface coating (chrome free) far exceeding ISO 4520 requirements (salt spray resistance: 240 hours for white corrosion and 500 for red corrosion). Some Q.Safe products also have the option to upgrade to our new E-Coat 1000 plating...

Q.SAFE QUICK COUPLINGS QUICK COUPLING SELECTION To ensure that you select the correct quick coupling for your needs, Manuli Hydraulics recommends that the following factors be considered: Pressure and Flow Rate - The selected quick coupling must always be suitable for the pressure and flow rate in the system. Always check that the selected quick coupling’s maximum working pressure is equal to or greater than the maximum pressure of the system (including pressure spikes). Connection Under Pressure - Many quick couplings can only be connected / disconnected when the line pressure has been...

Q.SAFE QUICK COUPLINGS MQS-DHI “DIRECT HOSE INTEGRATION” An innovative system to enable direct assembly of the quick-release coupling to the flexible hose, and therefore avoiding intermediate connection elements. Some of the benefits of this solution are: •  Reduced risk of oil leakage •  Elimination of unscrewing problems in the field •  Reduction in the number of assembly elements leading to reduced assembly cost, minimised risk of assembly operation mistakes and greater safety in severe working conditions, as well as easier maintenance and replacement operations Design solutions are...
