Instant, Leak-Proof Pneumatic Connections
Time is money on the assembly line. The PC8 Pneumatic Straight Fitting eliminates the need for hose clamps, compression nuts, and messy thread tape. Utilizing advanced Push-to-Connect (PTC) technology, you simply push your 8mm air hose into the blue release ring, and the internal stainless steel claws instantly lock it into place. This ensures a secure, high-pressure connection that won't blow out during heavy industrial operations.
Premium H59 Brass Durability
Don't compromise your automated machinery with cheap plastic threads that strip easily. The main body of this fitting is machined from high-density H59 brass alloy. This industrial-grade material offers exceptional resistance to thermal expansion, physical impact, and high-pressure stress. It guarantees a long operational lifespan, even in environments with constant vibrations and pressure fluctuations.
Pre-Applied Thread Sealant
Achieving a perfect seal has never been easier. Both the 1/8" and 1/4" PT male threads come with a factory-applied white Teflon sealant coating. This means you can screw the fitting directly into your solenoid valve, air cylinder, or manifold right out of the box—no need to waste time wrapping plumber's tape. Just tighten it with a standard wrench, and you are guaranteed a 100% airtight pneumatic circuit.
💡 Pro Tip from Our Technicians
"Pneumatic thread sizing is the number one cause of confusion for DIYers and junior technicians. A 1/8" PT thread does NOT measure 1/8 of an inch across with a ruler—it actually measures about 9.7mm in outer diameter. A 1/4" PT thread measures about 12.7mm. If you are repairing a machine and aren't completely sure which size you need, don't guess! Bring your air cylinder or old fitting directly to our Sham Shui Po store. Our team at Sun Cheong Computer Co. Ltd. will use our digital calipers to test-fit the exact PC8 adapter you need on the spot."

FAQ Section
FAQ Section
- How do I know if I need the PC8-01 or PC8-02?The "8" means it fits an 8mm outer diameter air tube. The "01" and "02" refer to the thread size. If the threaded hole on your air cylinder measures roughly 9.7mm across, you need the PC8-01 (1/8"). If it measures roughly 12.7mm across, you need the PC8-02 (1/4").
- Do I need to apply Teflon tape before screwing this in?No! Both the PC8-01 and PC8-02 feature a pre-applied white sealant coating directly on the threads. You can screw them into your pneumatic components right out of the box for a guaranteed airtight seal.
- How do I safely remove the 8mm air tube?First, ensure the pneumatic system is completely depressurized. Then, push the blue plastic release ring inward (towards the brass body) and hold it down while pulling the tube out. Never forcefully yank the tube without pressing the ring, as this will damage the internal locking claws.
