Perfect Engineers is an ISO 9001:2015 certified manufacturer, exporter, and OEM supplier of Quick Release Couplings (QRC) based in Mumbai, India. Built to serve a wide range of high-pressure, quick-connect fluid applications, our QRCs are precision-engineered for seamless integration across hydraulic, pneumatic, chemical, and gas systems worldwide.
Whether you’re dealing with water transmission lines or hydraulic equipment in extreme environments, our couplings reduce leakage, save time, and improve safety—without compromising performance.
A Quick Release Coupling (QRC) is a mechanical connector used to quickly connect or disconnect fluid lines without tools. It’s designed for fast and leak-proof service, often used in hydraulic and pneumatic systems. The full form of QRC is Quick Release Coupling, and it’s sometimes referred to as a Quick Connect or Quick Disconnect Coupling.
QRCs play a critical role in fluid transfer systems by reducing operational downtime and ensuring safe, secure connections. From compressed air lines to high-pressure hydraulic machines, QRCs simplify maintenance, reduce spill risk, and support automation.
Quick release couplings use a locking sleeve mechanism. When the male plug is inserted into the female socket, internal valves automatically open, allowing fluid flow. Upon disconnection, the valves shut instantly, preventing backflow or leakage.
Ideal for heavy-duty applications like hydraulic presses, cylinders, jacks, and high-pressure fluid systems. These QRCs can withstand up to 15,000 PSI and are built for pulse pressure durability.
Used in compressed air systems and pneumatic tool lines. Designed for quick and safe connections in automation, workshops, and assembly lines.
Flat-face design prevents fluid loss and contamination during connection and disconnection. Zero-spill, easy to clean.
Valves on both male and female sides prevent fluid loss when disconnected. Ensures complete fluid isolation.
Valve only on the socket side; plug side remains open. Common in air tools and non-hazardous applications.
No valves—maximum flow, minimal resistance. Not suitable for high-leakage-risk fluids.
Threaded locking mechanism ensures stability under vibration and pressure spikes.
Quick-connect couplers designed for one-handed operation. Auto-lock feature with sleeve release.

Quick Release Coupling.
A device used in pipelines to quickly connect/disconnect fluid lines in air, water, hydraulic or chemical systems.
By inserting a male plug into a female socket with an internal valve system that seals when disconnected.
Flat Face – typically refers to sealing face design in QRC or flanges.
Push-to-connect, threaded, or camlock-type self-sealing couplings.
Only if undersized; otherwise, they’re designed for efficient flow.
Measure the OD of the male/female plug or reference thread size (BSP/NPT).
It depends on your application—Flat Face for spill-free, Screw-Type for vibrations, etc.
ISO 7241-A/B, DIN Interchange, SAE, Parker, Stucchi-compatible formats.
