quick release hose couplings at times improve the efficiency of the application due to their custom design and compact size. The design of Pressure Washer Quick Release Coupling is such that the male end fits into the female socket that creates a secure and leak proof seal. high pressure quick release coupling is used for hydraulic wrench, emergency cutting tools, construction equipment, and industrial machinery. Quick Couplings are used in machinery that displays high pressure and vibration. Quick Disconnect Coupling that is designed to work under high pressure has a flat face design with a patented locking sleeve. Qrc needs to be connected between the locking pin and the release notch. Push Pull Couplings are made up of plastic or metal and are said to be light in weight. They can be produced in disposable material for cleanliness and hygiene purposes.

​Quick release couplings are fitting are used to mate fluid lines with system equipment that requires frequent connecting and disconnecting. They are used in both pneumatic and hydraulic applications to build or discontinue the connection of a fluid pipeline.

​It is well known as quick coupler, quick coupling or quick connect coupling. Quick coupling can be made of stainless steel SS316, carbon steel and brass material for practically every application contingency. ​The fittings size is available from 1/4” to 2”. The working pressure will be determined depending on the body size.

Hydraulic Quick Release Coupling is found in air, water, steam, and vacuum distribution system. The disconnection of lines leads to a rapid loss of fluid and hence they are connected with Qdc Coupling to prevent the rapid loss during disconnection. Stucchi Italy Quick Release Coupling is used to speed up the work and reduce cost. Din Couplings have made it easy to connect electrical equipment for operation. Holmbury Uk Couplings are well known to increase the output and reduce the downtime of the application. Nitto Interchangeable Series Qrc has eliminated the need for valves and screws in the pneumatic and hydraulic system. Female X Female Qrc is known to prevent the loss of expensive hydraulic fluid.

Male X Hose Qrc size depends upon the end use of the product. While purchasing Male X Male Qrc it is important to understand the pressure induced by the fluid system and the size of the system. Screwed Type Qrc is also widely used in many industries however care needs to be taken with regards to the fluid type and flow rate of the fluid. Ss 316 Quick Release Coupling is made up of high carbon grade of nickel and chromium when compared to its other version the Ss 304 Qrc grade.

What Is Quick Release Coupling ?

The fitting design is simple and easy to install, example a male end inserts into a female end to make a secure and leak-tight sealing. They are being called as push-in connect because the connection requires a quick push only. The fitting is manufactured according to different standard including ISO 7241-A, ISO 7241-B, Gromelle 6000, Hansen W6000, Parker 60, which are subjected to different industry applications.

Couplings are designed to change the connections without the use of tools or special devices. Quick Release Coupling is one such coupling that eliminates the need to close valves or bleed the system. quick release coupling manufacturers in India manufacture these couplings for various industries as they are high in demand due to their resistance to general corrosion. Quick Release Hose Couplings For Water offer leak-free performance with lightweight construction. quick release coupling for air has a pressure rating of 200 psi. Quick Release Connectors have a quick disconnect facility. Quick Release Hose Connectors are used to connect fluid lines to equipment that requires repeat connections and disconnections.

What size is a quick connect fitting?

The smaller the pipe size (OD), the higher pressure the fitting can withstand and it works respectively for different pipe size (OD). The fitting safety factor is 4.

How does a quick connect fitting work?

ISO 7241-A standard is versatile for use in hydraulic application for equipment maintenance or operation system. The fitting design is either a poppet valve or ball closing system. The poppet valve and a metal perch are used to maintain valve alignment and prevent flow duplication. Coupler sleeve and nipple body are hardened to be damage resistant and the standard end configurations include female pipe and straight thread of NPT or BSPP.

HYDRAULIC QUICK RELEASE COUPLING

ISO 7241-B or Parker 60 standard are poppet valves along with a metal to metal valve stop maintains valve alignment. It used to prevent flow duplication. The standard end configuration is female pipe thread of NPT or BSPP. It is generally for applications with lower life cycle and no severe cyclic pressure fluctuations, essentially applied in steady pressure during an operating cycle. The common applications include mine roof support system, hydraulic jacks and high pressure fluid transfer.

Screw end Gromelle W6000 or 203 Series TGW quick coupling is used to connect pipes under high pressure inline systems and high impulse hydraulic applications where fluid lines require fast and easy connection. Screw locking mechanism such as the 203 Series TGW provides exceptional resistance to severe hydraulic loads. This quick coupling is designed for severe conditions where hydraulic shocks, system vibrations or hose bending are possible.

Quick Disconnect Coupling Advantages

  • Designed to withstand high-pressure peaks and pulses
  • When connected the male and female halves can rotate, even under pressure, thus avoiding any torsional stress in the flexible hoses
  • Positive, quick connection ensured by the snap together locking ball system
  • Poppet valve seals have shockproof protective edges
  • Poppet valves have balanced springs and calibrated oil flow passages to minimize the pressure drop

How do you use quick connect fittings?

  1. Helps to keep contaminants out of fluid system.
  2. Protection from environmental dirt and grit which prolongs the coupling life and helps to keep maintain the fitting in
  3. excellent working condition.
  4. Colour coded plug and cap help to visually identify connecting lines.
  5. Tether straps keep the plug and cap nearby when coupling halves are connected.
