FAST INSTALLATION FOR PEAK PERFORMANCE

RIGOROUS CRITERIA NEED A SOLID SOLUTION With machines becoming more compact and power intensive, designing and manufacturing hydraulic platforms for a worldwide market is a difficult challenge. Manufacturers are demanding greater production line output without impacting key metrics like safety and leakfree connections. With existing threaded technology, meeting these rigorous criteria in an efficient way isn’t easy. That’s where Gates® Quick-Lok™ comes in. SAVE TIME, LOWER COSTS, AND REDUCE THE AMOUNT OF RE-WORK AND WARRANTY CLA

THE BENEFITS OF GATES QUICK-LOK Our family of threadless hydraulic couplings and adapters are designed to be leak-free and incorporate quick-to-connect technology. Gates Quick-Lok helps you save time, lower costs and reduce the amount of re-work and number of warranty claims. GATES.COM THE BENEFITS OF GATES QUICK-LOK 03

CONNECTORS: THREADLESS OR THREADED? THREADED CONNECTIONS – BE AWARE OF THE LIMITATIONS… Time it takes to assemble and torque a connection into place Difficult to install multiple hose assemblies in a tight space Lack of any visual indication that the correct amount of torque has been applied Incorrect torque can cause manifold leaks or a damaged port Threadless connections should be your first option to improve control over hydraulic assembly processes, reduce the probability of errors, and lower costly warranty claims. LEAK-FREE DESIGN y examining the sealing interface between port, adaptor,...

QUICK-LOK CONNECTORS ARE PRODUCED FROM HARDENED STEEL AND MACHINED TO EXTREMELY HIGH TOLERANCES.

A PROVEN TRACK RECORD We manufacture connections to ensure the highest integrity in port-to-port solutions. How? Quick-Lok connectors are produced from hardened steel and machined to extremely high tolerances. They have undergone rigorous testing under actual and simulated field conditions to confirm their strength and sealing ability. The Quick-Lok coupling family is proven to stand up to impulse loads, side loads, flex conditions, vibration, temperature extremes and vacuum conditions. TESTED, PROTECTED, SELECTED ■ Quick-Lok has been tested to ensure that the push-in force is high enough to...

ERGONOMIC ADVANTAGE AND INCREASED EFFICIENCY Quick-Lok couplings are threadless. With threading eliminated, checking torque settings for hose connections is no longer necessary. The easy installation process allows Quick-Lok to be used even in the most confined spaces often found in today’s compact machines. You also benefit from the cost-saving advantages that Quick-Lok delivers; for example, there is no need to invest in a vast range of expensive assembly tools or skilled assembly labor. Quick-Lok eliminates installer-dependent variation in the connection process (reducing rework time and cost)....

TWO CUSTOMIZED SOLUTIONS To fully accommodate customer needs, Gates has invested in two quick-connect solutions to customer connection problems. Whether your activities are in the hydraulic aftermarket or the hydraulic OEM business, we have a quick-connection that meets your needs – and exceeds your expectations. SOLUTION #1: QUICK-LOK HIGH (QLH) A quick-connect solution using a QLH adapter to establish a threadless port-to-port connection. QLH assemblies can be replaced either with threaded components or QLH threadless technology. SOLUTION #2: QUICK-LOK LOW (QLL) A low pressure quick-to-connect...

Quick-Lok High connectors are designed to be used in combination with 1-wire and 2-wire braid construction hoses. As a result, they are suitable to replace threaded connections in approximately 70% of current hydraulic applications. HIGH PRESSURE, HIGH PERFORMANCE QLH couplings are part of the Gates MegaCrimp™ product family, with proven expertise thanks to innovative design features: a MegaCrimp coupling with bite-the-wire tooth profile and patented C-insert ensuring a leak-free, concentric and full-length crimp that withstands impulse testing to 600,000 cycles, in combination with Gates Megasys™...

Changing over from threaded connections to QLH couplings for assembly production is as simple as replacing your current adapter with the QLH adapter. Equipment ports don’t require modifications to accept Quick-Lok adapters because the adapters are available in most common international termination types. Once installed, the adapter is ready to receive the QLH assembly. The unique Quick-Lok concept also reduces the need for a large component inventory and allows you to cover all of your product needs with fewer configurations. For total flexibility and convenience, QLH assemblies are suitable...

PARTIAL ASSEMBLY The QLH coupling is partially inserted into the QLH adaptor, engaging the O-rings. PRE-ASSEMBLY The QLH coupling is supplied with the necessary preinstalled seals and is protected by a disposable, protective cap. The QLH adaptor, also supplied with a protective cap and plug, can be pre-installed into the port of the equipment to save time on the assembly line. The coupling is fully inserted into the adaptor, creating a leak-free connection. For safety reasons (and to ensure a leak-free connection), once the QLH coupling is fully inserted, the connection is permanently locked...

MALE QUICK-LOK HIGH - 90° BENT TUBE QLH

QLL connections are an innovative solution originally designed for transmission oil cooler applications operating at a maximum working pressure of 3.4 MPa (500 psi). QLL is a low-pressure termination designed for use in non-impulse applications. The fluorocarbon O-ring allows it to be used with fluid temperatures between -40°C and +149°C. ■ Gates has been working in close partnership with leading OEM suppliers to develop QLL solutions - eliminating the use of adaptors ■ Reduce costs and increase time savings to your assembly line - QLL technology can be installed in one-tenth of the time of a...
