What is a quick couple or quick connect and where are they used

By David Edwards

Quick-connect couplings are connectors or fittings used to mate fluid lines with equipment that requires repeated connections and disconnections. They are used in both hydraulic and pneumatic applications, and are designed for easy hand operation for use with fitting attachments primarily on mobile machinery.

What are quick couplings used for?

Quick connect couplers are fittings designed for changing out lines quickly and easily. They are made to be connected and disconnected without the use of tools, or losing product. This eliminates the need to close valves, purge for trapped gases or bleed the system.

What is hydraulic quick connect?

Hydraulic quick couplings provide users with the ability to rapidly connect and disconnect hydraulic hoses to machines or other sections of plumbing. Also called quick-connects or quick disconnects, these fittings allow fluid to flow when the male and female sides are locked together.

What is a quick coupling valve?

Quick coupling valves allow hoses to be quickly connected to an underground irrigation supply pipe. Quick coupling valves are normally located under a valve box and are used for hand watering points or for connection of temporary irrigation sprinklers.

What is a coupling connector?

A coupling (or coupler) (used in piping or plumbing) is a very short length of pipe or tube, with a socket at one or both ends that allows two pipes or tubes to be joined, welded (steel), brazed or soldered (copper, brass etc.) together.

What is QC valve?

The Nelson Quick-Coupling (QC) Valve/Key system is an excellent solution for portable Big Gun® sprinkler systems. It allows the system to remain pressurized while the sprinklers are moved from position to position.

What is a turf valve?

Coupler Valve and Turf Key’s provide an innovative solution for having secure water points on your property. Using turf key’s mean that inquisitive livestock can’t open taps losing valuable water. … No more taps, the water is simply engaged when the “key” is inserted.

What are the different types of hydraulic fittings?

Why are There so Many Different Types of Hydraulic Fittings? While there might be hundreds if not thousands of hydraulic fittings and connectors, they all boil down to three basic types. These three types are either metal seal, soft seal, or tapered thread connectors.

What are the different types of quick connects?

  • Single End Shut Off Coupler.
  • Double End Shut Off Coupler (Standard Pressure)
  • Double End Shut Off Coupler (High Pressure)
  • QCDC Coupling:
What are couplings used for in plumbing?

Coupling & Adapter Fittings – Pipe couplers slip over the outside of two pipes to connect them, usually permanently. A coupling can be a reducer, or reducing coupling, meaning they reduce flow by joining a larger pipe to a smaller size. Adapters are used when connecting two pipes of different types.

What is a coupling used for in piping?

In water and wastewater piping systems, pipe couplings are used to connect two or more sections of pipe with the aim of maintaining continuity between them. They can be used to join pipes of different or equal sizes, as well as connect more than just two pipes if they are cross or T-shaped.

What are adapters used for in plumbing?

A fitting or adapter is used in pipe systems to connect straight sections of pipe or tube, adapt to different sizes or shapes, and for other purposes such as regulating (or measuring) fluid flow.

Where do sprinklers get water from?

It typically enters the house through a basement or crawl space below the house floors. A water meter is often installed on the water supply pipe in the basement or crawl space. The irrigation tap has to be after the water meter (if you have one.)

Where is the water source for sprinkler system?

Water for sprinkler systems can also come from natural or man-made bodies of water, such as wells, lakes, ponds, or reservoirs. Those static sources need to deliver the water in the volume and duration required by the system and the anticipated hose streams. And the water must be available 24x7x365.

What are gate valves made of?

Gate valves are typically constructed from cast iron, cast carbon steel, ductile iron, gunmetal, stainless steel, alloy steels, and forged steels. All-metal gate valves are used in ultra-high vacuum chambers to isolate regions of the chamber.

What does an isolation valve do?

An isolation valve is a valve in a fluid handling system that stops the flow of process media to a given location, usually for maintenance or safety purposes. They can also be used to provide flow logic (selecting one flow path versus another), and to connect external equipment to a system.

What is air relief valve?

Air Release Valves, or Air Relief Valve function to release air pockets that collect at each high point of a full pressured pipeline. … This greater force opens the orifice whenever air pockets collect in the valve. Air Release Valves are essential for pipeline efficiency and water hammer protection.

Do quick connects reduce water pressure?

This really depends on what quick connect system we’re talking about, as some will reduce water pressure while others will barely make a noticeable difference.

Are quick connects universal?

Universal interchange quick-connect air couplings are designed to work with other interchanges accepting multiple styles of nipples, including industrial, Tru-Flate, and ARO.

How does quick release coupling work?

They are designed with a spring loaded ball latching mechanism which automatically locks the two halves of the fitting together when they are pushed together. When the releasing sleeve (knurled for easy handling) is pulled back, the internal end and external ends quickly disengage from each other.

How do I know what size hydraulic fittings I need?

  1. First you should determine the length of a hydraulic fitting by laying it on a table and then stretching your measuring tape across the top of it.
  2. Next, determine the outside diameter of the fitting by using your ID/OD calipers.

Can you use brass fittings for hydraulics?

Although not one of the most common fittings used in fluid power applications, brass fittings are extremely useful in corrosive environments for both hydraulic and pneumatic hose and tubing applications. … They can be used with any copper, aluminum and steel hydraulic tubing that can be flared.

What's the difference between a coupler and a connector?

As nouns the difference between coupler and connector is that coupler is someone who couples things together, especially someone whose job it is to couple railway carriages while connector is one who connects.

What is the difference between a coupler and a coupling?

Are they interchangeable? Merriam-Webster dictionary doesn’t seem to think so. Among its definitions, a coupling is “a device that connects two parts or things”…. but, search coupler and you will find no reference for anything mechanical power transmission related.

What are the types of coupling?

  • Rigid coupling.
  • Flexible coupling.
  • Sleeve or muff coupling.
  • Split muff coupling.
  • Flange coupling.
  • Gear coupling.
  • Universal joint (Hooke’s joint)
  • Oldham coupling.

What is the difference between a pipe union and a coupling?

The basic difference between a coupling and a union is that coupling is for joining pipe to pipe or pipe to a swedge and the union is made for joining and disassemble a part of a piping system (a steam trap or control valve, etc) for maintenance or replacement.

What type of couplings are used on steel pipes?

Threaded Coupling We also named threaded pipe coupling as screwed coupling. They have thread at one or both ends that allows two steel pipes or tubes to be joined. The common thread types are NPT, BSPP and BSPT.

What are the 5 different pipe fittings?

  • Elbow.
  • Reducer.
  • Tee type.
  • Cross type.
  • Coupling.
  • Unions.
  • Adaptors.
  • Olet.

What are the common types of fittings?

There are many different kinds of fittings, made from a variety of materials: some of the most common types are elbows, tees, wyes, crosses, couplings, unions, compression fittings, caps, plugs and valves.
