MID has developed a new variable geometry coupling, which can swivel through 360 degrees: the DynaVariacor®. This internationally patented system provides in particular complete flexibility for use with all types of hoses.
The coupling is robust, light and compact; it reduces wear and avoids coiling of the feed hose. When it use with a nozzle this coupling enables increased precision of movement by reducing the handling force required by the user, due to the relative rigidity of the feed pipes. Operator comfort is improved. The DynaVariacor® products have useful features: the interior cross-section of the coupling remains constant at all angles, so pressure loss is minimised and flow rates are naturally optimum.
As well as air, these couplings are suitable for water, oil, petrol and hydrocarbons, and even powders. Many applications are therefore possible. For example, with fire hose or with rigid pipe : à load arm is then easy to make. The system is available in several sizes and fittings for a variety of uses.

Safe and quick multi-connection
Manually operated multicouplings
Features:
The hard-wearing and well proven manually operated multicouplings by WALTHER-PRÄZISION for the simultaneous connection of several gas, fluid and electric lines.
Due to the fixed assembly of the coupling elements a mix-up is impossible and the duration of the coupling process is shortened considerably. The multicouplings are used wherever process-reliable and semi-automatic operating sequences are required for production, test and control.
Automatically operated multicouplings
These couplings are used in/for automated operating sequences. The connecting movement is carried out electrically, pneumatically or hydraulically. Multicouplings in simple plate make-up may be equipped with different media and electric elements, depending on the requirement.
Key Benefits:
• high process reliability
• cost saving by quick connection
• documentable operating sequence for process monitoring
• increased operating safety / industrial safety
The following multicouplings are differentiated:
Multicouplings in simple plate make-up without motion module
Multicouplings in push-pull technique (with their own drive)
Multicouplings in shock absorber technique (balanced forces system)
Multicouplings in pull-in technique (balanced forces system)
Special docking systems

A rotating union must be capable of containing high pressures while
rotating at very high speeds.Smooth,easy rotation can only be
achieved by exactly mating the seal faces to minimize friction.
Precision and tight tolerances are critical in the micro lapping of sea
faces.All Deublin seals are micro lapped to an optical flatness within
2 light bands or 0.000023”utilizing proprietary lapping machinery
and compounds.This level of precision is essential for dependable
leak-proof operation.
Housings are machined on multi-axis twin-spindle lathes to obtain the
necessary part-to-part precision.Rotors and other parts are turned
on automatic bar machines to ensure true-running rotating unions
without any wobble.This assures extended service life.

The new BreakAway coupling from Colder Products Company provides safe and easy fluid transfer and protection from costly product loss and equipment damage. While heavy duty industrial versions of break-away couplings exist, there have been few options available for low pressure applications in plastic materials. These high quality, leak-free connectors allow the user to break the connection without depressing a latching mechanism for rapid, automatic disconnection when needed.
There is an increasing use of personal cooling systems across numerous markets. In some applications like automotive racing, a break-away coupling is mandatory. In other applications, it is an added convenience such as cooling vests for police officers, athletes or soldiers who may need to move quickly, and can't be tethered to a cooling device.
Colder's BreakAway couplings are available in acetal with Buna-N o-rings, 316 stainless steel valve springs, and automatic shutoff capabilities. Available in in-line and panel mount styles with 1/4" and 3/8" hose barb terminations, the coupling's maximum pressure rating is 20 psi (1.4 bar) and the temperature range is 0°F to 150°F (-18°C to 66°C).

IdentiQuik Smart Couplings™ with RFID Technology
IdentiQuik Smart Couplings™ from Colder Products combine the power and control of RFID and wireless ID technologies with the reliability and ease-of-use of Colder’s quick disconnect couplings. Their breakthrough design enables users to freely exchange data between two halves of a coupling at the time of connection. With Colder’s IdentiQuik Couplings, companies can achieve a new level of automation, safety and quality in their critical processes.
In its current configuration, the insert portion of the IdentiQuik Coupling contains a radio frequency identification tag that is programmed with unique product data, such as stocking history, package size, date code, or product characteristics. Prior to connection, the body portion of the coupling reads the tag and communicates with a wide variety of devices such as computers and programmable logic controllers using standard data interfaces. Examples include: recalibrating operating parameters base on the manufacturing lot of the consumable; locking out expired product; or preventing re-use of a single-use item.
The benefits of Colder’s IdentiQuik Smart Couplings include:
•Identify misconnections
•Save time
•Prolong equipment life
•Brand protection

Duff-Norton manufactures rotary unions, rotary joints, rotating joints and offers a line of 32 series ranging up to 10,000 psi and up to 5000 RPM. Rotary Union® is Duff-Nortons registered trademark for rotating joints.
Rotating joints are used to transfer fluids from a stationary supply to a rotating component, i.e., a drum or roll.
They are used in process industries like paper, printing, rubber and plastics, textile and chemical; on cranes, on machine tools and in a host of other applications. They are used to provide heating or cooling media like steam, hot oil, water or coolant to control the surface temperature of a drum or roll, to transfer air or hydraulic fluid to moving components or to add fluids to mixers while in motion.
Duff-Norton has traditionally served the markets where it supplies its general purpose joints, such as the rubber and plastics industries, and in the textile market it supplies its 8000T, a joint designed especially for the textile industry. The single largest user industry of rotating joints worldwide is the pulp and paper industry, which requires large quantities of joints for steam, water and hot oil. The steam applications (i.e., dryer cans) are most prevalent in paper mills.
