It has good high-pressure resistance and is mainly used in high-pressure and ultra-high-pressure pipelines.
Why Choose Quick Connect Fittings
Whether used in hydraulic equipment or other industrial machinery,our quick-connect couplings offer high pressure-bearing capacity,excellent sealing performance,and a smooth, tactile feel during connection and disconnection.
Allows for one-handed connection and disconnection, significantly reducing the time required for assembly and disassembly.
Features an internal valve mechanism that automatically closes upon disconnection, minimizing fluid or compressed air leakage and waste.
Precision sealing ensures reliability across various pressure ranges, from high-pressure hydraulics to low-pressure pneumatics.
Compatible with major thread standards (such as G, NPT, and BSP), making them suitable for piping equipment worldwide.
Seal materials—including NBR, FKM, EPDM, and Silicone—can be selected based on the specific application medium.
Constructed from high-strength materials with hardened valve cores and locking balls for consistent, reliable performance.
Manufacturing based on provided samples or technical drawings is available.
Suitable for Frequent Connection and Disconnection
Construction machinery and pneumatic equipment require repeated connection and disconnection, placing high demands on the steel balls and valve cores of quick-connect couplings.If quality is substandard, issues such as insufficient pressure, jammed steel balls, or valve seal failure can easily occur during this process;therefore,selecting high-quality quick-connect couplings is essential to prevent oil or air leaks.
Quick-connect Couplings with Various Pressure Ratings
Standard hydraulic quick-connect couplings typically operate at pressures of 40 MPa or less; high-pressure couplings operate in the 40–70 MPa range; and ultra-high-pressure couplings operate at pressures exceeding 70 MPa. For the same specifications, screw-locking quick-connect couplings offer higher pressure resistance and superior vibration resistance.

When selecting a model, you must verify the fluid type, operating pressure, temperature, material, and thread specifications, as well as whether a self-sealing function is required. If you have technical drawings or a sample of the old coupling, please be sure to provide them to us.
Yes, provided you select a corrosion- and chemical-resistant stainless steel coupling that is rated for your operating pressure.
Ensure the couplings are aligned during connection; do not force them together at an angle. Avoid exceeding the rated pressure. Regularly clean dust and debris from the locking balls and valve core areas. Do not force the coupling apart while it is under pressure, as this can cause fluid to spray out.
Common causes include worn seals, debris trapped on the sealing surface, or pressure exceeding the coupling’s rated limit. You can start by cleaning out any debris and inspecting the seal; if the component is worn or aged, simply replace the seal.
