Straight Male Threaded Coupling (4mm Push-In) with O-Ring
Industrial Grade Pneumatic Fitting
Ensure a precise, leak-proof connection in your robotic milking system with the 4mm Straight Male Threaded Push-In Coupling. Designed for the rigorous demands of a 24/7 dairy environment, this fitting features an integrated O-ring seal on the threaded base, eliminating the need for Teflon tape and ensuring a perfect, airtight seat every time.
Pneumatic leaks in small-diameter lines are a primary cause of intermittent sensor errors and sluggish performance in delicate components. This industrial-grade coupling provides a secure, vibration-resistant connection for 4mm air lines, commonly found in the Lely Astronaut magnet valve blocks and pilot-operated control lines.
Features & Benefits
- Instant O-Ring Seal: The pre-installed O-ring ensures a high-pressure seal against the manifold face, reducing installation time and preventing air loss at the thread.
- 4mm "Push-to-Connect": Features a high-tensile stainless steel grabbing ring that secures 4mm pneumatic tubing firmly while allowing for quick, tool-free disconnection.
- Compact Design: Ideal for high-density valve manifolds where space is limited, such as those inside the robotic arm or control cabinet.
- High-Cycle Durability: Built from nickel-plated brass and impact-resistant polymers to withstand the humidity and temperature fluctuations of a robotic barn.
- Vibration Resistant: Engineered to maintain a seal even on high-motion components that cycle thousands of times per day.

Technical Tip
When installing 4mm push-in fittings, precision is key. Because the tubing is smaller, it is even more susceptible to "side-loading" leaks if the tube is pulled tight at an angle. Always ensure your 4mm air line has a small amount of slack and is cut perfectly square. If you are troubleshooting a "ghost" air leak that you can hear but not see, check these small 4mm connections—a worn O-ring or a scratched tube end is a common culprit.
