Efficient Airflow Splitting & Reducing
Complex pneumatic systems often require splitting a main air supply into multiple smaller lines to feed various micro-cylinders or valves. The KQ2U Y-Type Reducing Fitting accomplishes this in one sleek, compact component. By combining a Y-splitter and a tube reducer into a single unit, it drastically reduces the number of fittings required, saving valuable space inside control cabinets and minimizing potential leak points.
Instant Push-to-Connect Technology
Time is money on the assembly line. This fitting utilizes advanced Push-to-Connect (PTC) technology. Simply push your polyurethane (PU) or nylon air hoses into the release rings, and the internal stainless steel claws will instantly lock them into place. To release the tubes, ensure the system is depressurized, press down the ring, and pull. No hose clamps, compression nuts, or tools are required.
Industrial-Grade Leak-Proof Design
Pneumatic leaks cause compressors to overwork and waste energy. The KQ2U series is engineered with high-quality internal NBR (Nitrile Butadiene Rubber) seals to guarantee a 100% airtight connection, even under maximum operating pressures of 1.0 MPa (145 PSI). The durable PBT plastic body ensures exceptional resistance to physical impact and harsh workshop environments.
💡 Pro Tip from Our Technicians
"Decoding pneumatic fitting models can be tricky! For the KQ2U series, the first number is the main input tube Outer Diameter (OD), and the second number is the output branch tube OD. For example, the KQ2U08-06 takes one 8mm tube and splits it into two 6mm tubes. Always make sure you cut your PU tubing perfectly straight (at a 90-degree angle) before inserting it to prevent micro-leaks. If you aren't sure which sizes you need for your robotic arm or CNC machine, drop by our Sham Shui Po store! Our team at Sun Cheong Computer Co. Ltd. will help you test-fit all your pneumatic components on the spot."

FAQ Section
FAQ Section
- How do I know which KQ2U reducing fitting size I need?Pneumatic push-to-connect fittings are sized based on the Outer Diameter (OD) of the air tube. If your main air supply line is 8mm OD and you want to split it to feed two smaller 6mm OD cylinders, you should select the KQ2U08-06 model.
- How do I safely release the air tube from the push-to-connect fitting?First, ensure the air supply is turned off and the line is completely depressurized. Then, push the plastic release ring inward (towards the center of the fitting) and hold it down while pulling the tube out. Never forcefully yank the tube without pressing the ring, as this will damage the internal stainless steel locking claws.
- What is the maximum operating pressure for these pneumatic splitters?These industrial-grade fittings are designed to safely handle a maximum operating pressure of 1.0 MPa (approximately 145 PSI or 10 Bar), making them suitable for almost all standard factory automation and DIY pneumatic applications.
