Product Description
This is a pneumatic push-in connector, not a CCTV product — it's stocked here as a general workshop/automation component alongside the camera range, for installers who also handle pneumatic control panels or air-actuated equipment on site.
The Festo QS-8-50 joins 8mm outer-diameter pneumatic tubing to a 1/2 inch male-threaded port. It's a genuine automation-industry fitting, so the notes below apply whether it ends up on a valve, cylinder, manifold or air preparation unit.
Key specs
- Tube fit: 8mm outer diameter push-in tubing
- Thread: 1/2 inch male, with sealant pre-applied at the factory — no PTFE tape needed
- Thread material: nickel-plated brass, giving corrosion resistance in industrial environments
- Fitting method: tool-free push-in; an integrated release ring lets you pull the tube back out for maintenance or reconfiguration
- Compatibility: stated by the manufacturer as compatible with Festo pneumatic tubing and automation equipment
Typical use
Anywhere an 8mm compressed-air line needs to terminate in a 1/2 inch threaded port — control panels, machine air lines, and general industrial pneumatic distribution. Not a camera-mounting or enclosure part; don't specify it against a CCTV bill of materials.
Fitting notes
Push the tube fully home until it seats against the internal stop — this is what gives the leak-resistant seal. To remove, depress the release ring evenly while withdrawing the tube; uneven pressure can mark the tube end.
Frequently Asked Questions
Is the QS-8-50 a CCTV accessory?
No — it's a pneumatic push-in connector, stocked here as a general automation component rather than a camera or CCTV part.
What tube size and thread does it take?
It fits 8mm outer-diameter pneumatic tubing on the push-in side and a 1/2 inch male thread on the other.
Do I need PTFE tape on the thread?
No — the thread comes with sealant pre-applied, so no additional sealing material is needed.
Can the tubing be removed and refitted?
Yes — it uses an integrated release ring so tubing can be withdrawn and reinserted for maintenance or reconfiguration.
