Why Choose Our QuickFit Connector
Many pneumatic fittings are limited in size, require multiple adapters or don’t match tube/tread combos you already have. This connector offers flexibility (multiple tube sizes + thread sizes) and ease of installation (push-in or threaded) which saves you time and avoids leak points. If you want one part that covers more of your system, this is the upgrade.

Perfect For (Occasions & Uses)

• Workshop and home-garage pneumatic systems where you need crisp, leak-free connections.

• Compressed-air hose maintenance, repair or upgrade (tools, sprayers, blasters).

• Automation or industrial equipment builders managing multiple tubing sizes and threaded ports.

• DIYers dealing with air-tool setups, hose expansions or custom pneumatic layouts.

How to Use / Care & Maintenance
Choose the correct coupling size: match tube outer diameter (4/6/8 mm) and thread size (1/8″–1/2″) to your system. Apply thread-sealant tape if needed on male threads, screw in connector to port, then push in tubing firmly until seated. For maintenance: periodically check for leaks, dirt/contaminant build-up, and hose integrity. When disassembling, depress the push-in collar (if applicable) and remove tube; always relieve system pressure first.
