45-Degree Pneumatic Tube Routing for Cleaner Machine Layouts
PLH Series push-to-connect fittings are designed to connect pneumatic tubing to a compatible female-threaded port while changing direction by approximately 45 degrees in compressed air and pneumatic automation systems. This category sits within PneumaticHub's Push To Connect BSPP (G) Thread Fittings range and is intended for parallel BSPP / G-thread pneumatic ports.
The one-touch fitting design allows compatible polyurethane, nylon and other suitable pneumatic tubing to be installed quickly and removed for maintenance when the system is safely depressurized. The fitting geometry is especially useful for metric and imported machinery using G-thread connections.

Why Use This 45° Male Elbow Fitting?
A 45-degree elbow can provide a more gradual tube path than a 90-degree elbow where machine geometry allows it.
Push-to-connect tube installation helps reduce assembly time compared with many conventional tube-connection methods.
Key Benefits
- Tubing can be disconnected and reconnected for maintenance or machine changes when the circuit is safely depressurized.
- Compact bodies help keep pneumatic plumbing organized around valves, cylinders, manifolds and control panels.
- Correct selection should consider tube outside diameter, male thread size, 45-degree orientation and clearance.
Common Applications
- Industrial automation machinery
- Pneumatic cylinders and actuators
- Directional control valves and manifolds
- Packaging and assembly equipment
- Robotics and material handling
- OEM pneumatic equipment
- General factory compressed air systems
Frequently Asked Questions
What is a 45° male elbow push to connect fitting used for?
It is used to connect pneumatic tubing to a compatible female-threaded port while changing direction by approximately 45 degrees in a pneumatic circuit. The exact connection arrangement depends on the model and the surrounding tubing or threaded components.
How does the push-to-connect connection work?
Compatible pneumatic tubing is pushed into the fitting until the internal gripping and sealing components retain it. The tube can be released using the fitting collar after the system has been safely depressurized.
What tubing is commonly used with these fittings?
The source category identifies polyurethane and nylon pneumatic tubing as common materials. Tube outside diameter and material should match the specific fitting.
What is the listed working pressure?
The source specification lists a working pressure of 0–150 psi(g) / 10 bar(g).
What is the listed proof pressure?
The source specification lists a proof pressure of 450 psi(g) / 30 bar(g).
Can these fittings be used for vacuum?
The source specification lists vacuum duty to 29.5 inHg / 14 mbar(a). Confirm the exact fitting, tubing and application conditions before use.
What is the listed working temperature?
The source specification lists 32–140°F / 0–60°C, with high-temperature models noted as available on request.
How do I choose the correct 45° male elbow push to connect fitting?
Confirm tube outside diameter, male thread size, 45-degree orientation and clearance, as well as pressure, temperature and tubing compatibility before ordering.
