Perfect Engineers offers a complete range of Quick Release Couplings (QRC) that are precision-crafted to meet diverse industrial demands—from hydraulic actuation to pneumatic automation. As an ISO 9001:2015 certified manufacturer with 35+ years of expertise, we engineer QRCs that ensure leak-proof connections, reduce downtime, and eliminate tool-based disassembly.
Each QRC type is uniquely designed to serve specific working pressures, connection styles, sealing systems, and application environments.
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.
