Q.Safe Quick Couplings
The Q.Safe Range
Q.Safe is the Manuli Hydraulics offering for quick coupling applications. Composed of more than 1,200 references, accessories and spare parts, the Q.Safe brand has rapidly become an industry byword for quality and performance.
The entire Q.Safe product range is manufactured with an environmentally friendly Cr3+ (trivalent chrome) surface coating, which offers excellent resistance to corrosion; far exceeding ISO 4520 requirements (salt spray resistance: 240 hours for white corrosion and 400 for red corrosion). Guaranteeing leak-free performance, the Q.Safe brand is suitable for a wide range of different applications and assures total interchangeability with other quick coupling products on the market.
All Q.Safe products are manufactured and assembled in our world-class facility in Poland, where they are subjected to stringent quality controls including:

Q.Safe Flat Face Program
One of the cornerstones of the Manuli quick coupling product range is the Q.Safe range of flat face quick couplings. Developed to cope with extreme conditions, the flat face range pushes the boundaries of what can be achieved by production model quick couplings.
The Q. Safe flat face range is comprised of four distinct flat valve models:
| MQS-F – Flat face coupling |
| MQS-FH - High pressure flat face coupling |
| MQS-FP - Flat face coupling with male connectable under pressure |
| MQS-FS - Screw type flat face coupling |
Each model has been designed to our uniquely high specifications, ensuring that it provides the best possible performance in whatever application it is used for. In fact, due to their unique hydrodynamic design, the Q.Safe flat face range of quick couplings provide the lowest pressure drop profile on the market.

The entire flat face product range provides the following benefits:
In addition to this, the FH, FP and FS versions have additional properties which make them suitable for their more specialised applications.
Q.Safe Flat Face Multiconnectors
The Q.Safe Flat Face range is widely renowned for representing the Gold Standard in quick coupling quality and performance.
The introduction of the Q.Safe Flat Face Multiconnector range combines this superior performance with the added efficiency and safety related benefits of a multiconnector block system.
Q.Safe Multiconnector Benefits:
| Reduces connection time when multiple connectors are used |
| No risk of incorrect connection |
| No misalignment between mobile and static blocks |
| Compact design for minimal added weight |
| Flat face couplings allow high pressures (350 bar) and high flow rates |
| Allows hoses to be arranged closer together whilst still allowing easy access |
| Industry leading performance with reduced pressure drop |
| Almost zero (between 0.007cc and 0.009cc) oil spillage on connection / disconnection |
| Connection under residual pressure |
| Easy to clean |

DHI – Direct to Hose Integration
The Q.Safe DHI program from Manuli Hydraulics is an innovative system which allows the quick coupling to be assembled directly to the hose.
Assembly of the quick coupling directly to the hose provides a number of important benefits over the more typical adaptor style fittings.
DHI solutions are available for ISO A, ISO B and flat face series quick couplings and offer the following benefits:
| Fewer components in the hose assembly reduces the cost of assembly operations and parts |
| Reduced number of components also minimises the number of potential leak points |
| Reduced risk of assembly operation mistakes |
| Easier maintenance and replacement operations |
| Quick coupling maintenance is possible without the need to replace the hose |
| Eliminates unscrewing problems in the field |
| Fewer components in the hose assembly reduces the cost of assembly operations and parts |
